绿色技术创新、智能化转型与制造企业环境绩效——基于门槛效应的实证研究

Green Technology Innovation,Intelligent Transformation and Manufacturing Companies'Environmental Performance:Empirical Research Based on Threshold Effect

绿色技术创新和智能化转型对破解资源环境制约、实现经济社会发展具有重要作用。以2011—2019年沪深A股上市制造企业为样本,构建双固定效应模型分析绿色技术创新对制造企业环境绩效的影响效应,并结合面板门槛模型探讨智能化转型程度差异下绿色技术创新对制造企业环境绩效的影响机制。研究发现,绿色技术创新对制造企业的环境绩效水平提升具有显著的促进作用。智能化转型正向调节绿色技术创新对制造企业环境绩效的提升作用,且其调节效应边际递增。当考虑异质性问题时,与中西部地区的企业相比,东部地区的企业的绿色技术创新、智能化转型对提升企业环境绩效的影响更明显;与国有企业相比,非国有企业进行绿色技术创新、智能化转型更易实现企业环境绩效的提升。研究结论为推动我国制造企业绿色技术创新、智能化转型以及改善企业环境绩效提供理论借鉴。

Green technology innovation and intelligent transformation play an important role in breaking resource and environmental constraints and realizing economic and social development.This paper selects data from manufacturing companies A-share listed in the Stock Exchange of Shanghai and Shenzhen from 2011 to 2019 as samples,constructs a two-way fixed effect model to analyze the impact of green technology innovation on the environmental performance of manufacturing companies,and adopts panel threshold model to explore the mechanism of how green technology innovation influences the environmental performance of manufacturing companies,which are at different stage of intelligent transformation.The empirical findings show that:(1)green technology innovation promotes the environmental performance of manufacturing companies;(2)there is a"threshold effect"brought by intelligent transformation.Intelligent transformation positively regulates the effect of green technology innovation on the environmental performance of manufacturing enterprises,and its regulating effect is increasing marginally;(3)when considering heterogeneity,the impact of green technology innovation on environmental performance and the threshold effect of intelligent transformation of manufacturing companies in the eastern region are stronger than those in the central and western regions.Additionally,the impact of green technology innovation of state-owned enterprises on the environmental performance of manufacturing enterprises and the threshold effect of intelligent transformation are weaker than those of non-state-owned enterprises.These findings are conducive to providing theoretical reference for promoting green technology innovation,intelligent transformation of Chinese manufacturing enterprises and improving the environmental performance.
