收入性补贴提高了中国小麦生产技术效率吗--基于随机前沿函数和技术效率损失函数的实证
Does the income subsidy improve technical efifciency of wheat production in China? An empirical study by a stochastic frontier analysis model with non-monotonic efifciency effects
摘要
Abstract
Applying a stochastic frontier model with non-monotonic efficiency effects, this paper analyzed the impacts of grain speciifc income subsidy on technical efifciency of wheat production during the period from 2002 to 2008 in China. Results show that: 1) average technical efifciency of wheat production is high in China, but signiifcant differences exist among provinces and regions; 2) from a national level, grain specific income subsidies lead to a decrease in technical efficiency of wheat, with the marginal effect increasing as subsides rising; and 3) among 19 provinces, positive effects of income subsidies exist only in four provinces and negative effects exist in other 15 provinces to different extent. These two different effects are combined results of three major grain policies, including income subsidy, minimum purchase price, and contingent storage. For the future of grain production, the Government should transform income subsidies targeted on grain production into “Green Box Policies” according to WTO rules.关键词
