摘要
文章以长三角41个地级及以上城市为研究样本,采用动态空间面板杜宾模型(DSPDM)及面板门槛模型(PTR)分析产业协同集聚与经济高质量发展之间的内在联系。研究发现:产业协同集聚对本地及地理相邻地区的经济高质量发展具有显著促进作用,且长期影响大于短期,但在经济水平相近的城市之间,产业协同集聚因“虹吸效应”存在而对周围地区产生负向空间溢出,该结论在一系列稳健性检验后依然成立。机制分析显示,在城市规模、外商直接投资及财政干预的约束下,产业协同集聚对经济高质量发展呈现非线性冲击。进一步分析表明,产业协同集聚对经济高质量发展的空间效应随地理距离增加呈现“先正后负”的演变趋势,400公里为其有效溢出边界;“宽带中国”试点政策有助于完善“互联网+”的产业生态体系,强化协同集聚的经济增长效应。
Taking 41 cities at or above prefecture level in the Yangtze River Delta as research samples,this paper uses the dynamic spatial panel Durbin model(DSPDM)and the panel threshold model(PTR)to analyze the internal relationship between industrial collaborative agglomeration and high-quality economic development.It is found that industrial collaborative agglomeration has a significant role in promoting the high-quality economic development of local and geographical adjacent areas,and the long-term impact is greater than the short-term impact.However,among cities with similar economic levels,industrial collaborative agglomeration has a negative spatial spillover to the surrounding areas due to the existence of“siphon effect”.This conclusion is still valid after a series of robustness tests.Mechanism analysis shows that under the constraints of city size,foreign direct investment,and financial intervention,industrial collaborative agglomeration has a non-linear impact on high-quality economic development.Further analysis shows that the spatial effect of industrial collaborative agglomeration on high-quality economic development shows a trend of“first positive then negative”with the increase of geographical distance,and 400 km is its effective spillover boundary;the pilot policy of“Broadband China”helps to improve the industrial ecosystem of“Internet+”and strengthen the economic growth effect of collaborative agglomeration.
