产业集聚多样化、专业化与企业绿色技术创新效率

利用2006—2018年省际层面数据实证检验产业集聚多样化和专业化对企业绿色技术创新效率的影响。研究发现:产业集聚多样化和专业化都显著促进了区域绿色技术创新效率的提升,其中,产业集聚多样化的作用更强。区域异质性检验表明,我国东部和中部地区的产业集聚多样化和专业化都显著提高了区域绿色技术创新效率,但是西部地区的产业集聚效应并不显著。产业异质性检验表明,国内第二产业和第三产业的专业化和多样化集聚均显著促进了区域绿色技术创新效率,尤其是第三产业的专业化和多样化集聚对绿色技术创新效率的提升作用要显著高于第二产业。

Diversification and Specialization of Industrial Agglomeration and the Efficiency of Enterprise Green Technology Innovation

This paper uses 2006-2018 inter-provincial data to empirically test the impact of industrial cluster diversification and specialization on the efficiency of green technology innovation.The study found that the diversification and specialization of industrial agglomeration have significantly promoted the improvement of the efficiency of regional green technology innovation.However,the role of industrial agglomeration diversification is stronger.The regional heterogeneity test shows that the diversification and specialization of industrial agglomeration in the eastern and central regions of my country have significantly improved the efficiency of regional green technology innovation,but the effect of industrial agglomeration in the western region is not significant.Industrial heterogeneity tests show that the specialization and diversification of domestic secondary and tertiary industries have significantly promoted regional green technology innovation efficiency,especially the tertiary industry specialization and diversification of green technology innovation.The promotion effect is significantly higher than that of the secondary industry.
