生猪养殖环境规制对绿色生产效率的影响

The Impact of Pig Breeding Environmental Regulation on Green Production Efficiency

在资源与环境双重约束下,提高绿色生产效率是生猪养殖绿色升级的关键。本文基于差异化技术创新视角,构建包含环境要素的索洛模型,以“强波特假说”为基础,通过大数据爬取2008—2019年中国省级面板政策数据,运用ML指数和系统GMM估计,系统检验环境规制对养殖绿色生产效率的作用路径与机理。研究表明:不同类型的技术创新对绿色生产效率有显著影响,生猪养殖的环境规制会弥补污染控制的技术创新,挤出生猪养殖的技术创新,最终降低生猪养殖的绿色生产效率。该研究能为生猪生产环境规制改革提供系统的理论指导。

Under the dual constraints of resources and environmental concerns,improving the efficiency of green production is key to the green upgrade of pig production.Based on the perspective of differentiated technological innovation,this study constructed a Solow model with environmental factors to test the impact of environmental policies on green production efficiency in pig production.Big data were used to crawl the data bars of China's provincial panel policy from 2008 to 2019 and analyses the pathways and mechanisms of environmental regulation on the efficiency of green production through the ML index and the two-step systematic GMM model.It was shown that different types of technological innovation have a significant impact on green production efficiency,the environmental regulation of pig breeding will compensate for the technological innovation of pollution control and squeeze out the technological innovation of pig breeding,which will ultimately reduce the green production efficiency of pig breeding.It also provides systematic theoretical guidance for reforming the environmental regulation of pig production.
