Texto completo da fonteIn the early 1990's it was started the price deregulation process of products of sugar-ethanol sector through the exemption of its prices. In this context, these prices started to be determined according to regulations of a free market. Since then, the sugar-ethanol sector has undergone profound changes in a considerably short period of time. This study aims to analyze price transmission among markets of main products of the sugar-ethanol sector in São Paulo State. It was determined the intensity and the duration in which price fluctuations are transmitted from a level of market to another and from one product to another of the same level. The analysis was carried out during the period of May 1998 and June 2002. The proposed model was implemented by making use of tests for unit root of Augmented Dickey-Fulley (ADF), of co-integration of Johansen and the method of Vector Auto-Regression with Error Correction (VEC). Results point to contemporary inter-relations among industrial crystal sugar prices in the domestic market and the market derived from exportation and among the prices of packed crystal sugar to producer and to retailing. The anhydrous ethanol price does not explain contemporarily the prices of industrial crystal and exported sugar. In the decomposition of forecast errors variance, it is noted the almost entire independence of the industrial crystal sugar price, the relating of anhydrous ethanol price to the industrial crystal sugar price and to the packed crystal sugar price to producer. The prices for exportation remain relatively independent from the variances of the domestic market. The price of packed crystal sugar to producer reveals dependency to the price of industrial crystal sugar and to packed crystal sugar to retailing. To the retail market the packed crystal sugar, almost all of its price variations are explained by the variable itself and by the producer's operating market price. In the impulse-response functions, results show that shocks to the industrial crystal sugar price causes a positive impact to the prices of anhydrous ethanol and of packed crystal sugar to producer with a time gap. Shocks to the anhydrous ethanol price causes a positive impact to the prices of industrial crystal sugar and to the exported crystal sugar only in fourth period after the shock. Shocks to exported crystal sugar price, basically does not cause any impact to the domestic market. The shock to the packed crystal sugar to producer has influence on the prices of industrial crystal and packed crystal sugar to retailing with a time gap and on the exported crystal sugar price in the fourth period. The shock to the packed crystal sugar price in the retail market causes a negative impact to the price of industrial crystal and packed sugar to producer. In general terms, results point to inter-relations among the prices of the products studied, once shocks to any of the variables lead to impacts in the direction to the others, specially after a short adjusting time. However, these relations did not reveal as expressive as expected.

Texto completo da fonteGeographical Indications (GIs) designate a particular label used to ensure quality, origin and protect products from counterfeiting. They bind the quality and the reputation of a product to a territory and are very present in Europe, especially in France. At a time when consumers are demanding more transparency and informations about the origin of the goods they consume, valuing local products represents an important issue. In this thesis, we analyze consumers' willingness to pay for products under geographical indications by using the Kantar WorldPanel database, which includes data of purchases of French households. With a focus on Auvergne PDO cheeses, we work on the period 2008-2010, which represents the period of reform and restructuring of actors in the Auvergne PDO cheeses sector. In a first step, we carry out a meta-analysis in order to observe what the studies tell us about the subject. Knowing that the willingness to pay is a price premium, we estimate the dispersion and the price determinants of Auvergne PDO cheeses in a second step. Finally, in a third step, we answer to our main research question by estimating determinants of choices and the consumers' willingness to pay (WTP). Globally, we find that the geographical indication plays an important role in the minds of consumers during purchasing activities, but in order to be more effective, it must be accompanied by promotion strategies initiated by distributors and producers. Similarly attributes of product and conditions of distribution play a more important role in the decisions of purchases, with regard to, the characteristics of consumers. Finally, we note that consumers have WTPs very different from a PDO cheese from Auvergne to another, but all these WTPs converge towards a single price, which represents the expected price of consumers for these products

Texto completo da fonteSince the rise in food prices in 2007-2008, agriculture is again at the front of the international scene. Political and human consequences of the turmoil in international markets have been significant in many countries and some had their government overthrown. In this context, we focus on rice, a cereal that guarantees the minimum caloric intake for more than 50% of the population, and on the rice farmer, the first link in the production chain. First we review the history of rice culture, the recent market developments and the rice crisis of 2007-2008. Secondly we are interested specifically in the transmission of international prices to producer prices, then we try to understand, from a macroeconomic and microeconomic point of view, the productive behavior of rice farmers in the variation of the price they get

Stocker cattle economic research is very limited in scope. A focus of this research is to deepen our understanding of how cattle price and animal performance variability is viewed and approached by stocker cattle producers in the United States. Another part of this research focuses on what characteristics may be drivers of whether producers choose to practice different risk management strategies. To analyze how cattle price and animal performance variability is viewed and approached by stocker cattle producers, a stated preference valuation method was used to find willingness-to-pay (WTP) estimates. Two different approaches were used to provide outcome probability information where one approach had probabilities for expected ADG change across scenarios and ADG ranges were held constant (Treatment Group A) and the second approach had ADG ranges change across scenarios and the probabilities were held constant (Treatment B). The results of our study suggest that survey respondents process scenarios differently when presented in formats Treatment Group A versus Treatment Group B. The underlying reason for this is beyond identification in this study as respondent certainty and comfort as assessed in follow-up questions was similar across the treatments. Results indicate that producers value buying cattle versus opting out of purchasing cattle and they value higher performing cattle; however, each additional pound is not valued the same. To determine the characteristics of producers and their operations that use different risk management practices, we estimated multiple probit models with the dependent variables being use of the different risk management practices. Results from the probit models suggest how producers source cattle for their operation, whether it is the region or the different markets they source from, are key determinants on whether producers practice different management strategies for market and price risk. The results suggest the model were not a good fit. Of the 30 explanatory variables included in the model, on average five explanatory variables were significant throughout the seven different dependent variables. This could be attributed to factors our study does not explicitly observe; therefore it remains a knowledge gap for the industry.

Texto completo da fonteDynamic rational expectation storage models were developed to represent the Brazilian corn market in the late 90s. In theses years the Brazilian agricultural price policy changed from a buffer stock scheme to a producer price subsidy (Prêmio para Escoamento de Produto PEP) and the Brazilian market was open to international trade. Any model in the existing literature was not able to represent the Brazilian corn market conditions. Acreage supply and consumption demand functions for corn the were estimated, as well as average values from 1986 to 2000 of annual storage cost, export and import prices, based on Chicago Board of Trade quotes. The annual interest rate was 12%. These functions and parameters were used to estimate the dynamic rational expectation models, through stochastic dynamic programming. The expected price and planted area functions were approximated by a fourth degree polynomial. The necessary algorithms were developed and results obtained using worksheets. Four models were estimated beginning with the situation of closed economy with no government intervention; closed economy with intervention through a producer price subsidy; open economy with no government intervention and open economy with intervention through a producer price subsidy. The optimal storage policies or storage rules for each model were obtained and used to generate 2.500 simulations of a 10 years path for each model. In these models, equilibrium price, consumption, storage and imports/exports are endogenous variables. Stochastic yields and demand shocks are exogenous variables. The long run means of the endogenous variables were calculated from the simulations and compared among models. The results show that with open markets, exports and imports play the role of shocks absorbers, played by storage in closed economies. Results suggest that the producer price subsidy policy may lead the country to be an exporter, depending on the relative values between minimum price and export price at the cost of ever increasing government expenditures.

Texto completo da fonteCorn is one of the most important Brazilian crops. Its harvest represents 37% of the total grain production in the country. And the potential of this sector gains even more strength with the increasing demand, both in domestic and international markets. Along with soybean, corn is the basic input for poultry and hog, two highly competitive international markets. But the corn production chain faces some important barriers, such as unclearly pricing in the market, trading problems, difficulty of access to private funding, and also low production yields. Taking into account the opportunities and challenges in the Brazilian corn market, this thesis aims to diagnose and analyze the factors that determine supply and demand in this sector, highlighting the importance of soybean in this context. The theoretical model price adjustment describes the Brazilian corn dynamic. An identification of the Sims-Bernanke justified the definition of a Vector Autoregression with Error Correction model VEC. This study shows that there is a strong interaction between corn and soybean markets - a relation of complementarity in supply and substitutability in demand - and that macroeconomic factors, such as income and interest, are crucial in the corn pricing, for growers and in the wholesale market. The productive soybean chain presents high technological development, international competitiveness, besides being widely explored in literature. International corn prices also influence the domestic values. These results are very important for policies related to food security and energy, as outlined in the conclusions of this paper.

Texto completo da fontePrices of agricultural products are experiencing significant volatility. Price volatility is still relevant today with food crises, the latest of which are those of 2007-2008 and 2010-2011. Trajectories may completely vary depending on whether we are targeting international market or national domestic markets. This price volatility represents price risk that affects farmers’ decision-making. This thesis is devoted to determine how producers react to the price risk of agricultural products. Specifically, it (i) reviews the available literature pertaining to decision-making in a deterministic or uncertain environment, (ii) analyzes the functioning of the Beninese agricultural sector by identifying the constraints on the sector and which constitute factors conducive to price volatility in the country’s main markets (iii) tests the existence of price volatility on food markets in Benin and assesses the extent to which agricultural prices have been volatile since 1995 and, ( iv) analyze farmers’ responses to price volatility. Results show that there is significant price volatility in the country’s main markets. However, it is established that changes in price volatility between the periods 1995-2005 and 2006-2015 vary according to the markets and products considered. The results also show that farmers in Benin react to price risk by increasing both production and corn acreage. The results of this thesis suggest, on the one hand, the use of transitional instruments for regulating the prices of food products and, on the other hand, the setting up of a counter-cyclical inventory control policy

Texto completo da fonteIn the chain of production of animal products, the feed mill is of fundamental importance in the economic and sustainability aspects. The main objective of this research is to improve the quality and efficiency of the production of poultry rations by reducing the nutritional variability of the ingredients. The study presents and discusses concepts of quality management focusing on the main inputs used in the industry. Through the bibliometric and content analysis of a selected portfolio in the international literature, it was possible to identify gaps related to the topic addressed. The nutritional variation of the ingredients allied to the establishment of classification criteria for suppliers of soybean meal was evaluated. A more efficient analytical method for nutritional analysis of soybean meal was also proposed, using near infrared spectroscopy, complementing with the analysis of the economical viability in the implantation of a maize segregation process in the animal nutrition industry as a way of increasing efficiency productive. Empirical studies were carried out involving raw materials from a feed mill of poultry located in the extreme western region of Santa Catarina, Southern Brazil. The study allowed to identify and discuss factors that influence positively and negatively the variation of the nutritional results of the rations. It is concluded that the analysis of the nutritional variation of the ingredients, the use of a supplier classification process, the proposition of an alternative fast ingredient analysis methodology using near infrared spectroscopy and the segregation of raw materials, are presented as effective methods to increase productive efficiency in feed mill.

Vegetables play a very important role in the daily diet consumptions for the Taiwanese people. However, due to climatic factors, vegetable prices often fluctuate. In order to maintain reasonable profits for farmers and purchasing power of consumers, how to adjust supply and demand of vegetables and to maintain stability of wholesale prices is a subject worthwhile to study. Due to the fact that the changes in vegetable prices can be a direct reflection of the vegetable supply and demand and consumption as well, this thesis focuses on the prices of vegetables in Taiwan. I use the transaction prices from the Taipei Agricultural Products Marketing Co., Ltd. to explore the relationships between the wholesale prices of vegetables and fruits and climatic factors. The empirical data are from 2002 to 2009 and include seven vegetable categories, (1) leaf vegetables, (2) flower and fruit vegetables, (3) root vegetables, (4) mushrooms, (5) preserved vegetables, (6) imported vegetables, and (7) overall and other vegetables. The ordinary least squares (OLS) method is used to forecast how climatic factors affect the consumption prices of vegetables in Taiwan.

The present study investigates the nature of the existence of long memory in agricultural products’ (soybeans, wheat, corn, and cotton) and precious metals’(platinum, silver, and copper) futures price at the daily return and volatility. The data are obtained from the Taiwan Economics Journal database. The agricultural sample collected consists of soybeans, wheat, corn, and cotton, whereas the precious metals sample consists of platinum, silver, and copper. The source for these data is CBOT and NYMEX. We test for the long memory in the daily returns and daily volatility using the modified rescaled range statistic R/S proposed by Lo (1991) and the rescaled variance V/S statistic developed by Giraitis et al. (2003). Empirical results show that agricultural products’ and precious metals’ futures daily return rate does not characterize the nature of a long memory, but volatility has a significant long memory. The findings of the current work provide a basis for agricultural products and precious metals in serving as the hedge futures.

The main purpose of this study was to test the predictive power of linear regression and time series models, find ways to predict the wholesale price of bananas. However, for the wholesale market price in Taipei, set the relevant variables of the model. The forecast of banana price using the data form 2006 to 2016, that includes plantain, scarlet banana and guava, in the wholesale market of the first and second markets in Taipei were used as model samples for model estimation and price forecast, The model accuracy is evaluated by means of root mean square error (RMSE), root mean square error percentage (RMSPE), mean absolute error percentage (MAPE), and Theil inequality coefficient. The results show that the linear regression model can show that it can improve the prediction efficiency and improve the prediction accuracy compared with the time series model. Therefore, linear regression models are used to predict banana prices or related studies.

The price of agricultural products and the degree of price fluctuations not only affect the consumption of people''s wellbeing, but also increase the uncertainty of agricultural production and impact on the farmers'' income. Therefore, ensuring stable and reasonable prices of agricultural products is one of the most important policies for many countries. The fluctuation of agricultural product prices is mainly affected by climatic conditions. The quality of agricultural products, the peak season of the growing season, etc., will also cause fluctuations in the prices of vegetables. To stabilize the price of agricultural products and promote the formation of agricultural product prices to be more open and transparent, the government have jointly invested with farmers'' groups and vegetable traffickers to establish Taipei Agricultural Products Marketing Corporation. The company is responsible for the operation of Taipei''s first and second fruit and vegetable wholesale markets. However, the Taipei Agricultural Products Marketing Corporation, which should have taken up the price of agricultural products in Taipei, broke out in the early 2018. Due to the excessively tight continuous closed market schedule, the agricultural product price collapsed, and the quantities suddenly increased when the market opened. The chaos of continuous closed market has caused a lot of controversy. Most of the studies focuses on the impact of climatic factors or natural disasters such as typhoons and cold damage on the price of vegetables. There are few related studies in Taiwan about the impact of continuous closed market on the vegetable prices. Therefore, this study aims to analyze the price fluctuations of six vegetables (cabbage, pekinensis, radish, corn, yam, spinach) before and after the market closures in 2011. In order to explore whether the price of vegetables will fall after continuous market closures, this study mainly uses the synthetic control method to analyze the impact of the 2011 lunar New Year festival and the Ghost Festival on the average wholesale price of vegetables. The empirical results show that, whether it is after a longer or shorter market closure, the price of vegetables at the opening of the market is relatively easy to have a lower price than without a market closure. It is indeed possible for the price of vegetables to be caused by the continuous closed market. The impact, which is further affected by the five consecutive days of the lunar New Year festival, is more significant. Among the six vegetables discussed in this paper, the continuous closed market has the most obvious impact on the wholesale price of cabbage. Also the study finds that in the absence of closed market, the average price will be higher than when the market is closed. Because the growth, harvesting and storage period of leafy vegetables are shorter, the price is significantly affected by the long-term closures. In contrast, the average price of rhizome crops such as radish and yam is less susceptible to the effect of continuous closures, possibly due to its longer growth, harvesting and storage periods. Finally, based on the empirical results, this study suggests that in the future Taipei Agricultural Products Marketing Corporation should include the effect of continuous market closures on the price of vegetables, and reduce the number of consecutive holidays in the long-term period to reduce the fluctuation of agricultural prices.

Texto completo da fonteThe relationship between farm and retail prices provides insights into marketing efficiency, consumer and farmer welfare. In light of this, much focus has been given to price transmission studies. Thus, price transmission studies have become increasingly important in Sub Saharan Africa because of its nature of providing clear insights information into our markets. Despite its importance in markets, there are a few studies analysing the mechanism through which prices are determined and transmitted from farm gate to retail markets in dairy markets in South Africa. The aim of the study was to investigate and analyse the nature of price transmission mechanism of pasteurised liquid milk and cheese in South Africa. The specific objectives were to determine the correlation between the milk production and quantity of milk processed in South Africa. Furthermore, there was a need to determine the direction of causality between the farm gate, processor and retail prices of cheese and pasteurised liquid milk in South Africa. It was also necessary to determine whether the price transmission of pasteurised liquid milk and cheese was symmetric or asymmetric in South Africa. The study used secondary time series data that covered a sample size of 17 years (2000 -2016) of pasteurised liquid milk and cheese in South Africa. Pearson correlation coefficient, Granger causality test and Vector Error Correction Model were used for data analysis. Pearson correlation results revealed that milk produced is perfectly correlated with the quantity of milk processed and it was positive. The Granger causality tests revealed that there was a no causal relationship between farm gate and processor, retail and processor and also between farm gate and retail for cheese. However, signs of independent causal relationship from farm gate to retail prices were visible. It also suggested a bidirectional causal relationship between processor and farm gate prices and also between retail and processor prices of pasteurised liquid milk. On the other hand, a unidirectional causality was found from retail to farm gate prices. The VECM results for pasteurised liquid milk showed asymmetric price transmission implying that retailers and processors react quicker to price increases than to price decrease. ii It is recommended that more focus be placed on investment in emerging dairy farmers in order to increase production. This can be done through the input price subsidies, grants and education on modern technologies. The government should also implement the price monitoring cell in order to protect the consumers from unfair prices passed on by the retailers.

Understanding crop seasonal effect and price trend is an important decision making for customers, crop farmers, and retailers. This research applied functional data clustering method to analyze crop price trend and variation. 15-year Taiwan agriculture crop price data were collected. The time-series data was first converted to functional data and the smoothing method was applied to obtain the function to represent each price curve. Then, Principal Component Analysis (PCA) was used to investigate the variation among the 15-year data. The hierarchical clustering method integrating PCA was proposed to study (1) absolute price trend, (2) price variation pattern, and (3) variation pattern among 15-year. The clustering result of the proposed method was compared with the model-based clustering method which is also used to cluster crops by their price functional data. The experimental result shows that the proposed clustering method is able to obtain the smaller sum of square error (SSE) which means our method can obtain the more impact clusters. Besides, the dimension-reduction is studied to use the relatively smaller dataset to maintain the same clustering result. The clustering result of agriculture crop price data can be provided to crop customers for enhancing purchasing decision making. The food retailers can also use the clustering result to monitor the price variation and detect the possible abnormal price trend for better operation decision.

This study aims to compare the predictive power of LSTM memory models with the traditional time series models. This study takes into account the impact of price and time on the model and aims to improve the prediction accuracy by changing the variables in the LSTM memory models. In the proposed study, the wholesale price of tomatoes was used as an example, and the price information of the Taichung market from 2003 to 2017 was considered. The results show that the LSTM models have an improved predictive ability. According to the predictive accuracy, the predictive ability of the model can be enhanced by referring to the highly correlated fruit and vegetable price. The model is capable of making relatively accurate predictions about one year in advance.

Is there any affection from macroeconomic variables(ex:money supply, foreign exchange rate and interest rate...) to agricultural department variables(ex:agricultural price, agricultural product quantity, farmers'' income) ? How do they affect agricultural department ? These problems are interesting to economic and agricultural economic scholars in 1980s''. This article adopts money supply , agricultural wholesale prices index , and urban''s consumers'' retail price index time series data in order to survey this problem. We transform the time series data to natural logarithm time series andto test Granger'' causality so as to survey the causality relationship. We get the following results: 1.The logarithm time series data will be stationary after differenced once. It is an I(1) time series. 2.Money supply and urban''s consumers'' retail price are mutual causality relationship. They will feed back to each other. 3.Agricultural wholesale product price is unique direction to urban''s con- -sumers'' retail price. On the contrary, it will not be true. 4.Money supply is also unique direction to Agricultural wholesale product price. On the contrary, it will not be true.

In recent years, we have often seen in the news reports that the price of fruits and vegetables has risen and fallen sharply. It greatly impacts on farmers' production and consumer prices. If there is a more accurate forecast of agricultural product prices, it could guide farmers' production decisions and stabilize price fluctuations. Based on the open data provided by the COA agricultural product price query system, this study used different time series models to predict the prices of different agricultural products, and compares them with the actual agricultural product prices to find the optimal forecast for different crops model. This results could guide farmers to make planting items and time decisions. After case study and analysis, it is found that each agricultural product had its own uniqueness. Furthermore, the fruits and vegetables would have a mutual substitution effect, especially in the summer when the fruit of Taiwan is rich in production. If it is caught in the hot weather, early harvesting would result in products price falling, and once it encountered a typhoon, it was another price trend. Therefore, there are not many measures that agricultural administrative units can adopt in monitoring the prices of agricultural products. The fundamental solution lies in the fact that farmers improve the quality of agricultural products, create their own brands and make market segments to decrease the impact of market price fall.

Extreme climate in Taiwan such as uneven rainfall and severe typhoon may cause great damages in agricultural products. Psychological expectation from both farmers and consumers about the provision may result in abnormal variation of crop price. In this paper, data were collected from relevant websites by web crawler, and a cloud artificial intelligence computing platform based on Keras was developed. The long-term and short-term memory algorithm (LSTM) model and various optimization parameters of RNN are utilized in the analysis. The prediction model of cabbage price was developed based on temperature、rain falls、and light luminance etc and the accuracy is about 17%.

Vegetables are sure to be in contact with everyone's life. The daily demand for vegetables and fruits in Taiwan is as high as 23,000 tons. Since vegetables are mostly perishable and can not be stored for a long time, the balance between production volume and demand will cause great price fluctuations. Farmers may also choose not to harvest because of the cost relationship, not only the glutinous rice farmers but also the waste. food. In view of this, this study takes the bulk vegetables of cabbage as the research object, discusses the relationship between volume and price, and collects the public data of the COA, Meteorological Bureau, and CPC, and analyzes the input variables with the inverted neural network. The relationship between vegetable prices and the data analysis of the batch data to explore the results reflected by different data, in order to identify the most suitable ethnic group data as the main observation object. Combine the six standard deviation management DMAIC improvement procedures, set a market buffer plan, and develop a project to control vegetable prices. Not only must we control the sales of fruits and vegetables in the domestic market, but we should also expand overseas markets to improve the problem of excess domestic production. After eliminating many variables, it proves that the previous day's trading price, relative humidity, air pressure value, presence or absence of typhoon, rainfall before 60 days, and oil price are the main variables affecting the price of cabbage. Finally, the best inverted transmission neural network structure is obtained. 6-8-1, 9~12 months, the overall average absolute percentage error (MAPE) of the cabbage forecast is 9.66, which is the minimum average absolute percentage error (MAPE) of 5.61 in October, which proves that the module is predicting the price of cabbage. Highly accurate predictive power.

With the global environment is rapidly change, the enterprises are facing competition not only domestic competitors, but a multiple market. When Taiwan accession to WTO, the agricultural development facing the free-market and competition, the agricultural products receive to severe competition and challenges from imported agricultural products. To consumers have connected, the regions of origin build a regional agriculture’s brand and through marketing mix to increase brand awareness. But the kind of regional brands is numerous that is important to how attract consumers to buy it. Therefore, this study is explore the effects of brand awareness, using perceives price and local image as moderators, on consumer’s purchase intentions, based on Social Exchange Theory to explore the effects of trust on purchase. This research has taken regional agriculture’s brand as subject, and collected data with responses. It got back 400 effective responses. The results of this study indicate that brand awareness, local image and trust are positively correlated with purchase intention. Especially, local image positive effects purchase intention than brand awareness and trust; Trust strongly moderator the relationship between brand awareness and purchase intention. Besides, purchase intention is not affected by brand awareness when local image and perceived price is used as moderator.

Recent years, Farmer-Fisher Associations’ top 100 agricultural products are local specially promoted by the Council of Agriculture and farmer associations. However, the food enterprises and private companies’ products become more diversified and competitiveness nowadays. How to make agricultural products stay attractive, competitive and retain consumers in the similar product categories is an important topic that should be further explored. And whether Council of Agriculture and farmer associations promote local special products to weakened consumer price sensitivity, it is necessary to be further explored. This study applied multiple hierarchical regression analysis approach to prove that official appraisal(third-party organization endorsement) has a negative correlation with price sensitivity from a total sample of 862 regular purchasers were investigated, and applied analysis of variance to compare different background of consumers in each dimensions. Overall results show that at least 30% of respondents are willing to pay 10 to 20% of extra budget to purchase top 100 agricultural products. In particular, the situational involvement played the role as having partly intermediary influences on the interaction between third-party organization endorsement and price sensitivity, but over 73% of respondents were only willing to pay less than one thousand dollars from their original purchased budget. Associations should increase third-party organization endorsement difference in the minds of consumers and use situational involvement to reduce consumer price sensitivity, the results can also provide as a reference to set appropriate prices, which can increase sales rate. This study suggests that the relevant official organizations and farmer associations should further promote products to potential consumer groups, and that promotion can increase situational involvement difference and farmer associations'' revenue. The conclusions can enhance competitiveness and sustainable of products.
