摘要: 基于2001-2015 年我国30 个省(区、市)数据,在“波特假说”和投资调整成本组合框架下,采用环境生产技术和固定效应模型测算和检验了环境规制及其对农业环境效率收敛的影响。研究发现,2009 年前后各省(区、市)环境规制成本呈现两阶段变化趋势,且存在显著的空间差异性。我国农业环境效率存在更显著的条件β 收敛但不存在σ 收敛。短期内环境规制对农业环境效率收敛的直接驱动效应显著为正,而中长期直接驱动效应显著为负。短期内农业投资存在较大的调整成本,农业投资以及环境规制的间接效应中长期才能够驱动农业环境效率收敛。整体而言,短期内农业环境效率收敛可以依赖环境规制直接驱动的路径,但中长期还是要依靠释放创新补偿效应的间接驱动路径。政府应尽快建立环境规制的强度标准,持续增加政府财政支农支出的力度,增加减排技术培训和优化种植结构。

Abstract: Based on the data of 30 provinces in China from 2001-2015, this paper uses environmental production technology and the fixed effect panel model to measure the cost of environmental regulation,and test its effect on the convergence of agricultural environmental efficiency under the integrated framework of “Porter Hypothesis” and adjustment investment cost.The research finds that the environmental regulation cost shows a two-stage changing trend around 2009,and it shows significant spatial differences among the provinces.The agricultural environmental efficiency has a more significant conditional β-convergence,but no σ-convergence.In the short term, the direct driving effect of environmental regulation on the convergence of agricultural environmental efficiency is significantly positive,while the direct driving effect is significantly negative in the medium and long term. In the short term, agricultural investment has a large adjustment cost,and agricultural investment and the indirect effect of environmental regulation can drive the convergence of agricultural environmental efficiency only in the medium and long term. Overall,in the short term the convergence of agricultural environmental efficiency can depend on the path of direct driving by environmental regulation,but in the long term it still depends on the indirect driving path of environmental regulation releasing the compensation effect of innovation.The government should establish the intensity standard of environmental regulation as soon as possible,continuously increase the government financial support for agriculture,increase the training of emission reduction technology and optimize the agricultural planting structure.
