环境污染约束下农业生产率增长地区差异及其动态分布演进

Regional Disparity and Dynamic Distribution Evolution of Agricultural Productivity Growth in China under Environmental Pollution Constraint

本文通过SBM方向性距离函数将环境污染因素纳入农业生产率分析框架,测算分析了环境污染约束下中国1998—2009年地区农业生产率水平,并考察了环境污染约束下农业生产率地区差距的动态分布演进及其影响因素情况。研究结果表明:不考虑环境污染约束将会高估中国整体的农业生产率水平;考虑环境污染约束的农业生产率没有出现收敛现象,各省农业生产率趋异的状态在未来很长一段时间内将持续存在;农村经济发展水平、农业基础设施投资、农业结构调整以及城乡收入差距对环境污染约束下的农业生产率有显著影响,是未来农业环境政策制定的重点。

Applying SBM directional distance function approach, this paper measured the agricultural productivity of China＇s 30 prov-inces from 1998 to 2009 incorporating agricultural pollution constraint and investigated the evolution of regional agricuhural productivity distribution through the dynamic distribution approach. The main results are as follows： ignoring agricultural pollution constraint will o-verestimate the overall agricultural productivity; it is not likely to find the phenomenon of regional agricultural productivity conver-gence, the regional disparities of agricultural productivity in China will continue for a long time; agriculture economic development, agricultural structure, agricultural infrastructure investment and income inequality have a significant effect on agricultural productivity under the environmental pollution constraint.
