绿色金融与技术创新耦合协调对低碳经济发展的影响

Impact of Coupling Coordination of Green Finance and Technological Innovation on Low-carbon Economic Development

绿色金融与技术创新耦合协调是发展新质生产力的重要着力点,是实现低碳经济发展的必由之路。本文选取2000—2021年中国省级面板数据,利用熵值法测算低碳经济发展综合指数,在此基础上使用双向固定效应模型检验绿色金融与技术创新耦合协调对低碳经济发展的影响。研究结果表明,低碳经济发展整体表现为稳定上升的趋势,且呈现“东高、中平、西低”的分布格局;省域绿色金融与技术创新耦合协调主要呈现高耦合协调度,且由沿海地区向内陆地区递减;绿色金融与技术创新耦合协调对低碳经济发展具有正向影响,同时绿色金融与技术创新耦合协调对低碳经济发展产生空间溢出效应。基于上述结果,为进一步优化绿色金融与技术创新协调发展和助力低碳经济发展,应注重“绿色”和“蓝色”资源优势,实施差异化低碳经济发展战略;以“空间治理”为抓手,促进区域绿色金融和技术创新协调发展;完善协同政策,有效提升新质生产力;加强区域空间重塑,充分发挥耦合协调的空间溢出效应。

The coupling coordination of green finance and technological innovation constitute a pivotal focus for fostering novel high-quality productive forces,as well as a crucial pathway towards attaining low-carbon economic development.To further examine whether this partnership promotes the low-carbon economy,this paper uses data from 31 provincial-level regions in China from 2000 to 2021 and adopts the entropy method to calculate the comprehensive index of low-carbon economic development.Moreover,it utilizes the two-way fixed effects model to test the impact of the coupling coordination of green finance and technological innovation on low-carbon economic development.The findings are as follows.Firstly,low-carbon economic development exhibits a consistent upward trend with a regional distribution pattern characterized by higher levels in eastern regions,moderate levels in central regions,and lower levels in western regions.Secondly,the coupling coordination between green finance and technological innovation demonstrates a high level,which gradually decreases from coastal areas to inland areas.Thirdly,the coupling coordination has a positive spillover effect on the low-carbon economy.This finding is still valid after a series of robustness.Fourthly,the coupling coordination is more significant in eastern regions,while its impact on the central and western regions remains limited.Therefore,it is recommended to implement differentiated strategies for low-carbon economic development based on“green”and“blue”resources,promote regional coordination between green finance and technological innovation through spatial governance measures,enhance coordinated policies to enhance new quality productivity,and strengthen the spatial spillover effect of coupling coordination by reshaping regional space.Compared to the existing literature,this paper makes the following contributions.Firstly,in terms of theory,it elucidates the impact mechanism of coupling coordination between green finance and technological innovation on China’s low-carbon economic development.Secondly,in terms of methodology,it evaluates the coupling coordination by constructing an evaluation index system and using the entropy method and the coupling coordination model.Thirdly,in terms of empirical analysis,it applies a spatial econometric model to assess the spatial spillover effect of the coupling coordination between green finance and technological innovation on low-carbon economic development.Finally,it analyzes regional heterogeneity in the impact of the coupling coordination on low-carbon economic development,emphasizing the urgency to improve green finance policies,promote technological innovation,and narrow regional development imbalances.
