中部地区出口贸易、产业专业化的耦合协同与绿色增长

Research on the Coupling Coordination between Export and Industrial Specialization and Its Impact on Regional Green Growth of Central China

论文从出口贸易、产业专业化耦合协同的视角探讨了中部城市绿色增长态势的形成机制,使用中部地区2006—2019年的地级市数据测度并分析了二者耦合协同度的时空演化态势,实证检验了其对区域绿色增长的影响效应和影响机制,研究发现:(1)中部地区出口贸易、产业专业化尚处于耦合协同的初级阶段,整体呈先增后降的态势,二者耦合协同在中部地区未显现出明显的空间聚类。(2)中部地区出口贸易、产业专业化的耦合协同不利于区域绿色增长。(3)中部地区出口贸易、产业专业化耦合协同拉大了一般地级市和省会城市的发展差距,刺激了政府增加财政支出力度间接不利于城市绿色增长,通过降低城市技术创新强度一定程度上间接抵消了对绿色增长的不利影响。(4)中部地区出口贸易、产业专业化耦合协同对绿色增长的影响因城市空间区位、城市特征差异显现出异质性。基于此提出了政策建议。

The coupling coordination relationship between export and industrial specialization in Central China makes their impact on regional green growth is no longer independent.The theoretical mechanism of the impact coupling coordination relationship between export and industrial specialization has been analyzed.Based on the data of prefecture level cities in Central China from 2006 to 2019,coupling coordination degree between export and industrial specialization of the region has been estimated,spatiotemporal variation of the degree has been analyzed,and its impact on green growth has been empirically tested through using econometric methods.The research shows that:(1)At present,the coupling coordination degree of export with industrial specialization in Central China are quite low which shows a trend of increased firstly and then decreased,and there is no obvious spatial clustering of coupling coordination degree in Central China.(2)Coupling coordination between export and industrial specialization in Central China is not conducive to regional green growth.(3)The coupling coordination between export and industrial specialization in Central China has widened the development gap between general prefecture level city and provincial capital,stimulated governments to increase fiscal expenditure,and then has had adverse impacts on green growth,and it has an indirect beneficial impact on green growth by reducing the level of technological innovation at the same time.(4)The impact of coupling coordination between export and industrial specialization in Central China on green growth is heterogeneous from the perspective of spatial location and city characteristics.Policy implications have been proposed.
