摘要
笔者从马歇尔、雅各布斯外部性及新经济地理的综合视角,通过建立面板VAR模型研究了我国生产性服务业集聚对城市经济增长的影响。结果表明:生产性服务业专业化、多样化和集聚规模与城市经济增长之间具有长期的均衡关系;生产性服务业专业化与多样化对经济增长具有单向因果关系;生产性服务业多样化无论在长期还是短期均促进了城市经济增长,而专业化却对经济增长产生负向效应。由于城市生产性服务业整体规模偏小,其对经济增长的规模效应尚不显著。鼓励生产性服务业多样性发展,避免同一部门的过度集聚,扩大重点生产性服务部门的运营规模可能是较为理想的政策安排。
Abstract： From the comprehensive view of Marshall externalities, Jacobs externalities and new economic geography,a dynamic econo- metric analysis is made on the effect of the agglomeration of producer services on economic growth across 286 prefectural or higher level cities for the period of 2000 - 2009 in China based on panel data VAR model. The results show that there exist long-term equilibrium relationships between the scale of producer services, specialization agglomeration and variety agglomeration of producer services and the local economic growth. And there exists one-way causality relationship between the agglomeration of producer services and economic growth. The variety agglomeration other than specialization agglomeration promotes economic growth. Because the total size of producer services is small, the scale effects of producer services on economic growth are not significant. Encouraging diversification of producer services in cities and avoiding over-agglomeration in the same sector, enlarging the scale of some important service sectors may he the expected policies.
