生产性服务业集聚机制与耦合悖论分析——来自长三角16个核心城市的经验证据

本文从全球价值链与国内价值链互动关系出发,分析了生产性服务业的空间集聚机制,并以长三角16个核心城市为例对生产性服务业集聚的现状及其耦合悖论进行了理论解析和实证检验。本文研究的主要结论有,第一,在跨国公司主导的国际生产体系中,长三角以代工方式参与国际分工的模式,客观上导致制造业和生产性服务业的空间集聚存在着非同步性;第二,长期以来长三角过度依赖加工贸易方式参与国际分工体系,在很大程度上限制了生产性服务业集聚的程度,原因是跨国公司在对外投资时往往倾向于自带服务,生产性服务外化程度较低,长三角这种低端嵌入的外向经济模式,严重抑制了生产性服务业的发展和空间集聚;第三,信息技术对长三角生产性服务业的驱动作用较弱,长三角虽然是我国高等级的城市群,但技能型人才与生产性服务业的匹配程度并没有达到预期的效果。为此,在第二波全球化中,迫切需要整合全球创新要素来提升国内创新链。

Producer Services Agglomeration Mechanism and Coupling Paradox --Empirical Evidence from 16 Core Cities in Yangtze River Delta

From the perspective of the interactive relationship between global value chain and internal value chain, thispaper analyses the mechanism of producer services agglomeration, and conducts statistical and empirical analysis of couplingparadox about producer services agglomeration, based on the data of 16 core cities in Yangtze River Delta. The result showsthat, first of all, at present multinational-dominated international production system, Yangtze river delta participates in inter-national division of labor by the way of OEM, which objectively lead to coupling paradox about the agglomeration of manufac-turing industries and producer services; second, long-term excessive dependence on processing trade to participate in the inter-national division of labor system, largely hindered the producer services spatial agglomeration, the reason is that multinationalcorporations tend to bring their own services in foreign investment, thus producer services externalizing degree is low. Nowa-days, Yangtze River Delta is at a disadvantage situation in global value chain of low-end embedded export-oriented economicmode, which severely inhibited the development and spatial agglomeration of producer services ; third, the driving effect of information technology on the producer services is weak; finally, as our country＇s high-grade city group, skilled talents and ag-glomeration of producer services do not achieve its corresponding matching effect. Therefore, in the second wave of globalization, it is very crucial to integrate global innovation elements to improve domestic innovation chain.
