不同规模生猪养殖的成本收益及全要素生产率的动态实证分析
Dynamic Empirical Analysis on Cost-benefit and Total Factor Productivity of Pig Breeding in Different Scales
摘要
Abstract
Exploring the profitability and total factor productivity of different pig breeding models is of great significance for the high-quality development of the pig industry and the effective supply of pork.This paper analyzes the component income of different pig breeding models with the provincial panel data from 2009 to 2019,and measures and decomposes the total factor productivity of different pig breeding models using the Malmquist index method of DEA model.The results showed that the scale breeding mode had a comparative advantage in cost,the profit of scale breeding was higher than that of free-range breed-ing,showing periodic fluctuations,and the free-range breeding mode had the largest fluctuations.The total factor productivity of different breeding modes increased slightly,which was mainly due to the improve-ment of technical changes,but the technical efficiency showed an overall decline,which was caused by the double drag effect of pure technical efficiency and scale efficiency.Based on this,this paper puts forward some suggestions,including large-scale breeding,policy subsidies and improving total factor productivity.关键词
