中文摘要:

      基于内生增长理论建立计量模型,以2002—2017年中国地级市数据和国家级经济技术开发区数据为样本,依据国家级经济技术开发区数量变化,分阶段分区域实证分析了国家级经济技术开发区进口外溢对区外城市经济增长的影响。研究发现:2002年的54个国家级经济技术开发区进口外溢阻碍了区外城市的经济增长,这种阻碍作用从东部、中部到西部地区依次增加；区外城市的工业化水平、人力资本水平、基础设施水平未达到门槛值是产生这种结果的机制。进一步的研究发现,2010年、2011年和2012年随着国家级经济技术开发区数量的增加,其进口外溢对区外城市经济增长的作用由阻碍转为促进。因此,应努力增加国家级经济技术开发区的数量,提高区外城市的工业化水平、人力资本水平、基础设施水平,完善国家级经济技术开发区进口产品结构,以发挥国家级经济技术开发区进口外溢对区外城市经济增长的推动作用。相对于中东部地区,西部地区更应如此。 

英文摘要:

      Based on the theory of endogenous economic growth to construct an econometric model, with the data of Chinese cities and the state-level economic and technical development zones (ETDZs) during the years from 2002 to 2017 as samples, according to the change in the number of ETDZs, this paper empirically analyzes the effects of import spillover of state-level ETDZs on the economic growth of cities outside the state-level ETDZs in different stages and different regions. The research shows that the import spillover of 54 state-level ETDZs in 2002 hinders the economic growth of the cities outside the state-level ETDZs and the obstacle increases from the east region, the middle region to the west region in turn. The levels of industrialization, human capital and infrastructure of cities outside the state-level ETDZs do not reach the threshold value, which is the mechanism to produce such result. Furthermore, with the increase in the number of the state-level ETDZs in 2010,2011 and 2012, the effects of their import spillover on the economic growth of the cities outside the state-level ETDZs change from obstacle to promotion. Therefore, great efforts should be made to increase the number of the state-level ETDZs, raise the level of industrialization, human capital and infrastructure of the cities outside the state-level ETDZs, and improve the import structure of the ETDZs, so as to play the role of import spillover of the state-level ETDZs in promoting the economic growth of the cities outside the state-level ETDZs. Compared with the middle and east regions, this is especially true for the western region. 
