Research On The Effect Of Price Support Policy Changes On Soybean Production In China

Policy is the wind vane of agricultural development.In recent years,agricultural policy has been constantly adjusted,aiming to activate the market,the main body and the elements,so that the pricing power of agricultural products returns to the market,and at the same time to ensure the self-sufficiency of main grain and the basic income of farmers.For the revitalization of soybean,the importance of agricultural policy is self-evident.Since wto accession,China has launched a series of agricultural policies to promote soybean production and soybean production situation during the policy implementation also presents different change,thus to study the effect of price support policies of soybean production mechanism,at the same time to explore other influencing factors for the government in the future to develop soybean subsidy policy has a certain reference.In view of this,this article is based on 2001-2016,10 major soybean producing areas of the country's soybean planting area and per unit area yield of panel data,at the same time the introduction of soybeans,soybean land costs,soybean imports,alternative crops(corn)income and agricultural policy variables,such as the use of Nerlove model to China's soybean supply response has carried on the empirical analysis.Innovation point of this study was to join the latest implementation of soybean market purchase producer subsidy policy,in the majority of research only add planting area based on the dependent variable,in the empirical part will be planted area and production at the same time as the dependent variable in the research,makes the result more perfect.The results showed that soybean planting area,soybean price,soybean import quantity,soybean land cost and soybean temporary purchase and storage policy were the main factors affecting soybean production.However,soybean yield per unit area was significantly affected by soybean import volume and soybean price.The adjustment time of optimal soybean planting area was 3.97 years,while the adjustment time of optimal soybean yield per unit unit was 1.46 years.The price of soybean has a positive effect on the total production of soybean,but the effect is weak.The short-term price elasticity of price variable is 0.077,and the long-term price elasticity is 0.305.The three policies have certain effects on soybean yield increase in theory,but in the empirical results,the effects of the three policies on soybean yield increase and planting area expansion are not consistent.Finally,some policy Suggestions were put forward to promote soybean production in China.
