摘要
文章基于2003-2018年长三角地区41个地级市的面板数据,从理论和实证两方面检验了Mar外部性、Jacobs外部性和Porter外部性在政府作用下影响区域创新能力的作用机制.研究发现,集聚外部性对区域创新能力的影响存在不确定性,二者之间存在基于政府作用下的门槛效应;受政府作用的影响,集聚外部性与区域创新能力之间存在非线性关系,这种非线性关系在三种集聚外部性中有所差异,且政府的调节作用方向存在异质性.因此,应结合不同集聚外部性形成的集聚模式,对地方政府角色定位进行调节和规范,做好市场调研,有效回应各类型产业的需求,动态调整政府作用方向和水平,以最大限度避免政策有效供给不足和时滞问题.
Abstract
With the panel data of 41 cities in the Yangtze River Delta from 2003 to 2018,this study ex-plored the mechanisms by which Marshallian externalities,Jacobs externalities,and Porter externalities af-fected regional innovation capacity under the role of the government.The results showed that the impact of ag-glomeration externalities on regional innovation capacity presented uncertainties,and there was a threshold ef-fect between agglomeration externalities and regional innovation capacity when the government played a role.Under the influence of the government,agglomeration externalities had a non-linear relationship with regional innovation capacity.Moreover,the non-linear relationship was different among the three different agglomera-tion externalities,and the regulatory role of the government was heterogeneous.Therefore,the modes of differ-ent agglomeration externalities should be considered in the adjustment and standardization of the role position-ing of local governments.Market surveys should be conducted to effectively respond to the needs of various in-dustries.Furthermore,the direction and level of the government role should be dynamically adjusted to avoid insufficient and delayed policy supply as much as possible.
