环境约束下我国西南地区农业全要素生产率度量及收敛性研究

Calculation and Convergence of Agricultural Total Factor Productivity in Southwest China Under Environment Regulations

摘要:

本文首先用清单分析法对我国西南地区农业面源污染进行核算，将其纳入农业全要素生产率框架，并基于Malmquist-Luenberger生产率指数和新古典收敛模型实证分析我国西南地区农业全要素生产率增长及其演进规律。实证结果显示：考虑环境约束的农业全要素生产率显著低于传统不考虑环境约束的测算结果，反映出西南地区农业经济呈现以牺牲生态环境为代价的粗放型增长；环境约束下“桂川渝”地区农业全要素生产率高于“云贵”地区，贵州农业发展呈现出典型的“增长与环境”双重恶化现象；环境约束下西南地区农业全要素生产率存在收敛和收敛,但是收敛趋势并不稳定。基于上述结论，本文提出了相关政策建议。

Abstract:

This paper selected list analysis method to calculate agricultural non-point source pollution in the southwest China, then putted it into total factor productivity analysis framework,finally applied the Malmquist-Luenberger productivity index and the neo-classical convergence model to empirical analyze southwest China agricultural total factor productivity growth and the evolution law.The experiential results show that:firstly,considering environmental regulations of the agricultural total factor productivity was significantly lower than traditional calculation results, reflected that southwest agricultural economy development presents extensive growth at the expense of ecological environment;secondly, under environmental regulations agricultural total factor productivity in Guangxi、Sichuan、Chongqing province are higher than Yunnan and Guizhou province,especially Guizhou agricultural development was typical "growth and environment" deterioration;lastly,agricultural total factor productivity in southwest area under environmental regulations exist σ-convergence and β-convergence, but σ-convergence is not stable. Based on the above conclusions, related policy implications are recommended in the paper.
