| As a pillar industry in animal husbandry economy,pig industry is also an important source of meat consumption of Chinese residents.Its healthy and stable development is the premise of stable economic income of a large number of farmers,and stable pork price can be ensured by avoiding large losses of farmers.Northeast pig-producing areas in China,one of the four major areas are classified as potential area,from the point of live pig market scale,northeast China is still in the four main bottom,there is plenty of room to improve,as representative of pig-producing areas in northeast China,Jilin province from nearly 10 years of breeding stock and market volume,only 2%of the country’ s,and to save such amount,the larger fluctuation amplitude.From 2001 to the beginning of 2019,the pig price experienced four times of drastic fluctuations,and the documents and policies issued by the government in response to the price fluctuations did not achieve the expected effect.Imbalance between supply and demand is one of the important reasons of price fluctuation,pig farmers and market is the relationship between each other,the farmers production decision,"what have what,a","when such","when is larger or smaller breeding" from several aspects to influence the supply of live pigs,indirect impact on market prices.Therefore,starting from the perspective of prospect theory and from the perspective of farmers’main body,this paper explores the influencing factors of their decision-making behavior and the decision-making behavior preferences of farmers with different characteristics under the price fluctuation.Based on the prospect theory,this paper constructed a theoretical model,explored and studied the influencing factors of pig farmers’decision-making behavior in jilin province by using SPSS and AMOS,analyzed the decision-making behavior preferences of pig farmers with different characteristics under the price fluctuation,and gave corresponding Suggestions based on the empirical analysis and research results.The results show that:(1)it is reasonable and applicable to study the farmers’decision-making behavior by using the structural equation model(SEM)constructed by the prospect theory.Due to the natural growth characteristics of pigs,the prospect of profit or loss is estimated through the psychological account,and the breeding subject adjusts the reference point to make the decision of expanding or reducing the breeding scale.(2)under the common constraint of internal and external factors,the breeding subject makes"bounded rational decision",and its risk preference is inconsistent in the profit period and the loss period,showing asymmetry.(3)farmers’ decision-making behavior under uncertain conditions is directly influenced by individual characteristics,family characteristics,risk preference,market information and external information;At the same time,the external environment has an indirect effect on the pig breeding behavior decision,which is manifested in that the external environment indirectly influences the pig breeding behavior decision by influencing the market information.(4)farmers with long breeding time tend to maintain the breeding scale or expand the breeding scale under the prospect of loss;The better off households are,the more likely they are to keep or expand in size in the context of a profit-and-loss outlook;Under the loss prospect,the pig price information can affect the farmers’ behavior decision more.Therefore,the decision-making behavior of farmers is indeed related to the fluctuation of pig price.In order to alleviate the fluctuation of pig price,the government should implement the whole policy to farmers to understand and meet the reasonable demand of farmers,so as to create more profits for farmers and stabilize the fluctuation of pig price.Finally,this paper gives four points:(1)improve the pig industry organization degree.(2)continue to promote insurance policy subsidies and develop diversified pig breeding insurance products.(3)improve the pig trading information service platform.(4)formulate protection measures for pig prices and establish an early warning system. |
