Agglomeration Externalities,Government Role,and Regional Innovation:A Study of Threshold Effects Based on Data of 41 Cities in the Yangtze River Delta
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.
