Study On The Impact Of Agricultural Subsidy Policy On Chinese Rapeseed Production

In the context of stabilizing China's domestic edible oil safety,this paper focuses on the impact of China's agricultural subsidy policy implemented since 2001 on rapeseed production.This paper mainly introduces the production of Chinese rapeseed since 2001,including changes in rapeseed yield,acreage change and annual yield,and analyzes the spatial variation of rapeseed production in China according to the actual conditions of different main producing provinces.At the same time,in order to study the impact of agricultural subsidy policy on rapeseed production,the article refers to “two subsidies”(good subsidies and comprehensive subsidies for agricultural materials),agricultural machinery purchase subsidies,grain and oil county reward funds and rapeseed temporary storage and storage.The specific implementation of the subsidy policy related to rapeseed production is introduced.Based on the panel data of 15 provincial-level units of China's rapeseed production from 1990 to 2016,through the CD production function model,including the “two subsidies” policy and agricultural machinery purchase subsidy policy and the labor input involved in rapeseed production,The relationship between the input and output of rapeseed production,such as the use of agricultural machinery,the amount of fertilizer used,and the rent of land transfer,was estimated.The purpose was to measure the specific impact of the above two subsidy policies on the annual rapeseed production.Based on the panel data of rapeseed production and price in each province from 2001 to 2016,the Nerlove supply reaction model was used to estimate the regression variables including rapeseed market price,rapeseed artificial light cost and temporary storage policy,mainly for the estimation.The impact of the temporary storage and storage policy of rapeseed on the change of rapeseed acreage.Through the calculation of the above two models,it is concluded that the “two subsidies” policy and the temporary storage and storage policy have a significant positive impact on China's rapeseed production,while the agricultural machinery purchase subsidy policy has a significant negative impact on rapeseed production.influences.Secondly,this paper uses the Malmquist production index model to calculate the total factor productivity and its sub-items of the major rapeseed producing provinces in China from 2004 to 2017.The main purpose is to provide a sufficient empirical basis for the proposed policy recommendations.The results show that there is a defect in the production of rapeseed in China,which leads to the negative growth of the total factor productivity of Chinese rapeseed in the measurement interval.Although there is a certain difference in the growth rate of total factor productivity among provinces,there is still much room for improvement in the promotion of rapeseed modernization and mechanized production in the provinces.Finally,according to the production information of Chinese rapeseed over the years,the C-D production function,the relevant conclusions of the Nerlove supply reaction model and the calculation results of the Malmquist productivity index,some theoretical suggestions for the implementation of the agricultural subsidy policy for rapeseed production in China are proposed.
