绿色技术创新能力、产品差异化与企业竞争力——基于节能环保产业上市公司的分析

Green Technological Innovation Ability, Product Differentiation and Enterprise Competitiveness: Analysis of Energy Saving and Environmental Protection Industry Listed Companies

本文以2011-2016年间我国节能环保产业上市公司为研究样本,实证检验绿色技术创新能力、产品差异化与企业竞争力的关系,同时分析企业规模对绿色技术创新能力与企业竞争力关系的调节作用。研究发现,绿色技术创新能力对企业竞争力有显著的正向影响,绿色技术创新能力的各个组分对企业竞争力的影响存在差异。产品差异化在绿色技术创新能力与企业竞争力的关系中发挥中介作用,产品差异化在绿色技术创新能力的四个组分与企业竞争力的关系中的作用存在差异,此外,企业规模在绿色技术创新能力与企业竞争力关系中具有正向的调节作用,产品差异化在企业规模的调节作用中起中介作用。本文的研究为解读绿色技术创新能力影响企业竞争力的内在机理提供了一个有价值的新角度。

Can an enterprise’s green technological innovation ability enhance its competitiveness?This topic has not been studied extensively,there is no consensus in the existing literature,and there is no clear indication of the underlying mechanism and processes.In this research,a conceptual framework is established to describe the effect of an enterprise’s green technological innovation ability on enterprise competitivenes.This model uses product differentiation as the mediating variable and the enterprise scale as the moderating variable.This study is based on a hierarchical regression analysis of the energy conservation and environmental protection data from enterprises listed in China from 2011–2016.Our findings show that,in general,the green technological innovation ability of an enterprise has a significant positive effect on the enterprise’s competitiveness,but different components have different effects on enterprise competitiveness.Product differentiation has a mediating effect on the relationship between an enterprise’s green technological innovation ability and competitiveness,and its mediating effect differs depending on the components of the green technological innovation ability.The enterprise scale positively moderates the relationship between the enterprise’s green technological innovation ability and enterprise competitiveness through product differentiation.A new analytical framework is provided to understand the mechanism underlying the effect of an enterprise’s green technological innovation ability on enterprise competitiveness,and useful insights are provided into the development of green technological innovation competitiveness and the establishment of new policies by the government is presented to improve the regulatory framework for green development.
