环境规制对农业绿色全要素生产率的影响研究——基于面板门槛模型的分析

Impact of Environmental Regulation on Agricultural Green Total Factor Productivity——Analysis Based on the Panel Threshold Model

本文运用SBM超效率模型和GML指数测算了2000—2017年中国的农业绿色全要素生产率,并进一步运用面板门槛模型考察了环境规制影响农业绿色全要素生产率的非线性效应。研究表明,2000—2017年,中国农业绿色全要素生产率不断提升,年均增速达到3.39%;环境规制对农业绿色全要素生产率的影响存在显著的双重门槛效应,随着阈值区间的提高,环境规制的负向影响呈逐渐减弱的趋势;高阈值区间的种植业比重、贸易依存度和劳动力文化水平有利于降低环境规制对农业绿色全要素生产率的负面影响,而高阈值区间的受灾程度则会加剧环境规制对农业绿色全要素生产率的负向影响效应。

This paper uses the SBM super-efficiency model and the GML index to measure the agricultural green total factor productivity in China from 2000 to 2017, and further examines the nonlinear effect of environmental regulation on agricultural green total factor productivity through the panel threshold model. The result shows that: from 2000 to 2017, China’s agricultural green total factor productivity has been continuously improved, with an average annual growth rate of 3.39%;the impact of environmental regulation on agricultural green total factor productivity has a significant double threshold effect, with the increase of threshold interval, the negative impact of environmental regulation is gradually weakened;the proportion of planting structure, dependence on foreign trade and labor’s culture level in high threshold interval is beneficial to reduce the negative effect of environmental regulation on agricultural green total factor productivity, while the degree of disaster in high threshold range will aggravate the negative effect of environmental regulation on agricultural green total factor productivity.
