Study On Dynamic Interaction Of Agricultural Product Price In Heilongjiang Province

Chinese residents have a tradition of drinking milk daily.In order to meet the growing milk consumption needs of residents,dairy farming is particularly important.And many factors will have an impact on the dairy farming industry.China's vast land and resources,different provinces have different resource endowments for the development of dairy farming.Therefore,all provinces(autonomous regions)should give full play to their comparative advantages in dairy farming,rationally plan the layout of dairy farming,increase the utilization rate of resources in various regions across the country,and improve the yield of Chinese dairy co ws.This plays a very important role in stabilizing the Chinese dairy market and enhancing international competitiveness.Therefore,it is of great practical significance to study the breeding layout of Chinese dairy cows from the perspective of regional comparative advantages.With the continuous development of China's agricultural market economy,the price fluctuation of agricultural products has become more and more complex.Especially in recent years,the frequency and extent of the price fluctuation of agricultural products have caused serious damage to the agricultural market,which has become the focus of attention of all sectors of society.The drastic change of agricultural product prices may not only damage the interests of producers,but also affect the economic interests of all stakeholders in the industrial chain of acquisition,processing,wholesale and retail.The price of agricultural products will be affected by many factors.Based on the perspective of price linkage,this study studies the spillover relationship between different prices of agricultural products.Firstly,the non-linear causality between prices of agricultural products is tested and analyzed,and then the social network structure of Heilongjiang agricultural products is constructed according to the results of the test analysis,and the generalized impulse response analysis and variance decomposition analysis are used.This paper empirically examines the non-linear dynamic interaction between prices of different agricultural pro ducts.The results show that rice and maize are in the leading position in the price network structure of Heilongjiang agricultural products,and they are in the central position of the price linkage network and control the price linkage of other commodities.Meat and fruit are followers,while vegetables are price recipients in the Internet.There is a general positive impact effect between the prices of agricultural products,but the response of different agricultural products to price shocks is different.When rice is affected by price shocks of other agricultural products,the price response of rice is not strong and the time of price adjustment is relatively short,while the time of adjustment of maize and wheat is relatively long in the face of price s hocks of the same kind of food crops,and the time of adjustment of meat for maize is relatively long.The regulation time is the shortest.When vegetables face the impact of other agricultural products,the regulation time is generally longer,especially for meat.The adjustment time of price shocks of fruits for other agricultural products is generally short.Based on the price linkage effect between agricultural products,this paper examines the spillover relationship of agricultural prices from a non-linear perspective.By grasping the relationship between prices of different products and further studying the price of agricultural products in China,we should not only explore the factors affecting prices,but also grasp the mechanism and trend of price changes,and ultimately help the government make correct market decision-making choices,maintain the stability of supply and demand of agricultural products market,reduce the financial burden of the state,and promote the reform of agricultural supply side.
