生产性服务业集聚与制造业转型升级的机理与实证检验

摘要

理论分析表明生产性服务业集聚通过降低贸易成本和提升创新收益的中介效应推动制造业转型升级，实证研究发现该外溢效应依赖于城市经济基础和区位环境的支撑，同时还要克服阻碍这种外溢跨区域传递的制约条件。区域性中心城市和先发工业化城市已表现出生产性服务业集聚对制造业转型升级的积极影响，但知识密集型服务业集聚尚缺乏对制造业的创新驱动作用。%Through mediating effects brought by reduction of trade cost and increase of innovation benefit proposed by the theoretical analysis , producer services agglomeration has a positive influence on manufacturing transformation and up -grading .An empirical study shows such spillover effects not only depend on supports of economic basis and location envi -ronment of city , but also break constraints that prevent transition of the spillover across different regions at the same time.The positive influence has shown in those regionally central and early industrialized cities .However, there is still no innovation-driven effect over manufacturing resulted from knowledge intensive services agglomeration .
