“双碳”目标下制造业绿色创新效率及区域协调发展论析

Analysis on Green Innovation Efficiency of Manufacturing Industry and Regional Coordinated Development under the "Double Carbon" Goal

摘要:

基于“双碳”目标下创新转型及区域协调绿色共享发展的迫切要求，本文分绿色科技研发和绿色成果转化两阶段，运用超效率SBM模型及GML指数测度具有典型创新效应的高技术制造业的绿色创新效率，使用空间自相关性检验与空间计量方法研究高技术制造业绿色创新效率的空间溢出效应，实证结论表明：高技术制造业两阶段绿色创新效率均呈上升走势，成果转化阶段绿色创新效率相对低，存在区域异质性；高技术制造业两阶段绿色创新效率均表现为正向空间溢出效应；7个影响因素分阶段存在正负不同的空间溢出效应。针对结论，从推动产学研联动、促进区域协同、放大环境规制外部正效应、增强区域基础设施连接以扩大绿色技术辐射面等角度提出针对性对策建议。

Abstract:

Based on the urgent requirements of innovative transformation and regional coordinated green and shared development under the "dual carbon" goal, this paper measures the green innovation efficiency of high-tech manufacturing industries with typical innovation effects by applying the super-efficient SBM model and GML index in two stages: green science and technology R&D and green achievement transformation, and uses spatial autocorrelation test and spatial econometric method to study the spatial spillover effect of green innovation efficiency of high-tech manufacturing industry.The empirical results show that the green innovation efficiency in the two stages of high-tech manufacturing industry shows an upward trend, and the green innovation efficiency in the achievement transformation stage is relatively low and there is regional heterogeneity; the two stages of green innovation efficiency of high-tech manufacturing industry both show positive spatial spillover effects;the seven influencing factors have different positive and negative spatial spillover effects in stages.According to the conclusions, countermeasures and suggestions are put forward from promoting industry-university-research linkage, promoting regional coordination, amplifying the external positive effects of environmental regulations, and strengthening regional infrastructure connection to expand the radiation surface of green technology.
