摘　　要：本文利用2003—2011年中国十大城市群的面板数据,采用动态GMM估计方法研究了产业集聚对经济效率的门槛效应,并对威廉姆森假说和开放性假说进行了验证。研究结果表明:(1)产业专业化集聚对于没有跨越经济发展水平门槛值的城市群经济效率具有明显的阻滞作用,而对其他门槛作用下的城市群没有显著影响;(2)产业多样化集聚对跨越城市群规模门槛和处于所有经济发展水平阶段的城市群经济效率具有显著的正向影响,但对其他门槛作用下的城市群的影响不显著;(3)提高对外开放程度,加快第二产业、第三产业协调发展将有利于提升城市群的经济效率;(4)在产业专业化和多样化集聚对城市群经济效率的影响效应中没有找到支持威廉姆森假说的经验证据,但从产业多样化集聚视角验证了开放性假说在中国的适用性。最后,本文据此提出了相应的政策建议。This paper studied the threshold effects of industrial agglomeration to regional economic efficiency with dynamic GMM estimation method based on panel data of China＇s top ten urban agglomeration areas from 2003 to 2011.Williamson hypothesis and openness hypothesis were verified in this paper.The empirical results showed that the industrial specialization agglomeration would hinder economic efficiency under the threshold level of economic development of urban agglomerations,but no significant impacts on the urban population under other threshold effects.Industrial diversification agglomeration could significantly promote economic efficiency above the threshold of population size and all stages of level of economic development of urban agglomerations.But the impacts on urban agglomerations under other threshold effects were not significant.Improvement of openness and the coordinated development of the industries and the services would be conducive to enhance the economic efficiency of urban agglomerations.The impact effects of industrial specialization agglomeration and diversification agglomeration to the economic efficiency of urban agglomeration did not support for the Williamson hypothesis.But the industrial diversification agglomerationverified the applicability of the openness hypothesis in China.Finally this paper put forward the corresponding policy recommendations.
