摘要
基于2010~2021年长江经济带城市面板数据,全面考察战略性新兴产业对绿色发展的影响。结果显示:战略性新兴产业发展能够显著减轻环境污染,有利于长江经济带实现绿色发展,且在上游、中游、下游地区以及成渝城市群、长江中游城市群、长三角城市群之间存在异质性影响。战略性新兴产业通过提高经济集聚、人才集聚、技术集聚促进区域绿色转型发展,且战略性新兴产业对绿色发展的影响存在基于自身规模大小的门槛效应,在跨越门槛值后,其对节能降耗、绿色发展的促进作用会进一步减弱。同时,战略性新兴产业发展水平较高的地方,人才集聚及技术集聚的绿色溢出效应更明显,且经济集聚带来的规模经济效应能够在一定程度上弱化其产生的“拥挤效应”和“搭便车”等资源浪费、效率低下现象。鉴于此,应注重人才集聚的创新溢出效应,加快实现技术集聚,提高战略性新兴产业集聚区的准入门槛,并适度扩张战略性新兴产业的发展规模。
Based on the panel data of cities in the Yangtze River Economic Belt from 2010 to 2021,the impact of strategic emerging industries on green development is comprehensively examined.The results show that the development of strategic emerging industries can significantly reduce environmental pollution,which is conducive to the realization of green development of the Yangtze River Economic Belt,and there are heterogeneous effects in the upstream,midstream and downstream regions,as well as among the Chengdu-Chongqing urban agglomeration,the city agglomeration in the middle reaches of the Yangtze River,and the Yangtze River Delta urban agglomeration.Strategic emerging industries promote regional green transformation and development by improving economic agglomeration,talent agglomeration and technology agglomeration,and the impact of strategic emerging industries on regional green development has a threshold effect based on its own size,and after crossing the threshold,its promotion effect on energy saving,consumption reduction and green development will be further weakened.At the same time,where the development level of strategic emerging industries is higher,the economy of scale effect brought by economic agglomeration can weaken the"crowding effect"and"free-riding"and other resource waste and inefficiency phenomena to a certain extent,and the green spillover effect of talent concentration and technology concentration is more obvious.The green spillover effect of talent concentration and technology concentration is more obvious.In view of this,we should pay attention to the innovation spillover effect of talent concentration,accelerate the realization of technology concentration in the region,effectively reduce the production cost and improve the utilization rate of resources,and moderately expand the development scale of strategic emerging industries.
