【摘要】：基于2004—2013年中国29个省份的面板数据,分别使用SML指数、空间自相关和空间β收敛分析方法对环境约束下规模生猪养殖全要素生产率的时空分异趋势及收敛性进行分析。研究发现:中国规模生猪养殖全要素生产率主要受到技术进步的拉动在考察期内以年均5.29%的速度增长,技术效率在波动中无明显改善;随着技术进步度过快速空间外溢时期,地区间规模生猪养殖全要素生产率增长的正向空间溢出作用经历了先增后降的变化趋势;HH类型地区以中南区为基础逐渐向西北方向的重庆和陕西扩张,LL类型地区在北方以及华东区的连片分布范特征逐渐增强,HL类型和LH类型地区的连片特征趋于减弱;中国规模生猪养殖全要素生产率增长存在显著的绝对β收敛和条件β收敛特征,经济发展水平、畜禽养殖业发展水平和农村人力资本水平是影响收敛性的主要因素。
[Abstract]:Based on the panel data of 29 provinces in China from 2004 to 2013, the temporal and spatial differentiation trend and convergence of total factor productivity (TFP) of scale pig breeding under environmental constraints were analyzed by using SML index, spatial autocorrelation and spatial 尾 convergence analysis. It is found that the total factor productivity of pig breeding in China is mainly driven by technological progress. During the inspection period, the total factor productivity of pig breeding increases at an average annual rate of 5.29%, and the technical efficiency does not improve significantly in the fluctuation, and as the technological progress passes through the period of rapid spatial spillover, The positive Spatial spillover effect of Total Factor Productivity growth in Intra-regional scale Pig breeding has experienced a trend of first increasing and then decreasing. HH type areas gradually expand northwestward to Chongqing and Shaanxi LL-type areas based on the central and southern regions. In the north and east of China, the characteristics of continuous distribution normalcy are gradually enhanced in HL type and LH type area, and the characteristics tend to weaken. There are significant absolute 尾 convergence and conditional 尾 convergence characteristics in the total factor productivity growth of Chinese scale pig breeding. The main factors affecting convergence are the level of economic development, the development level of livestock and poultry industry and the level of rural human capital.
