随着中国跨入服务经济时代,作为承载经济空间活动的城市群将致力打造服务业高层次开放协同发展平台,吸引FDI向服务业集聚,促进区域可持续发展。基于空间经济视域,本文通过分析西部地区成渝城市群2005—2014年空间面板数据,阐释FDI和服务业集聚的经济效应,促进成渝城市群发展,希冀缩小东、中、西部城市群发展差距。实证分析显示:FDI、国内资本、人力资本以及服务业集聚对经济增长的贡献度依次降低;FDI通过技术外溢效应为城市群经济增长带来巨大动力;但由于服务业集聚空间分布呈现明显的“两极化”特征,因而未能显现对区域经济的整体提升作用。因此,增加及引导FDI流入服务业,促进资本、劳动力等要素在城市群内自由流动,优化服务业集聚空间分布,深化城市群产业集群内分工协作,助推服务业跨界融合,培育梯度产业价值链将是实现城市群区域协调发展的重要路径。
As China enters the era of service economy, urban agglomerations carrying economic space activities will strive to create a platform for high-level, open and coordinated service development, attract FDI to the service industry and promote regional sustainable development. Based on the perspective of space economy, this paper analyzes the economic panel data of Chengdu-Chongqing urban agglomeration from 2005 to 2014 to explain the economic effects of FDI and service agglomeration, promote the development of Chengdu-Chongqing urban agglomeration and hoping to reduce the development of urban agglomeration in eastern, central and western China gap. Empirical analysis shows that the contribution of FDI, domestic capital, human capital and service agglomeration to economic growth are decreasing in turn; FDI spurs great momentum for economic growth of urban agglomeration through technology spillover effect; However, due to the obvious spatial distribution of service agglomeration, “Polarization” characteristics, thus failing to show the overall promotion of the regional economy. Therefore, it is necessary to increase and guide the inflow of FDI into the service industry, promote the free flow of capital and labor in the urban agglomerations, optimize the spatial distribution of service agglomeration, deepen the division of labor and coordination within the industrial agglomeration of urban agglomerations, boost the cross-border integration of service industries and foster the gradient industry Value chain will be an important way to achieve the coordinated development of urban agglomeration.
