中文摘要：

区域服务业时空演化动力机制研究是对服务业演化规律的一种探索,也是服务业研究的重要内容之一。目前对服务业演化动力机制研究多从某个或几个因素阐释其对服务业演化的影响。本文以服务产品和空间的相关理论为基础,主要从时间和空间两个维度构建出贯穿市场供需、空间集散和政府调控等基本因素的区域服务业时空演化动力机制理论框架,并运用该框架对长三角地区服务业时空演化动力机制进行了实证分析。结果表明：长三角地区服务业时空演化是供需机制、空间集散机制和政府调控机制共同作用的结果。其中,供需机制发挥着主导作用;空间集散机制也产生一定影响,尤其是生产性和消费性服务业表现较为明显;政府调控机制也反映出市场化程度的提高有利于促进部分类型服务业的发展。

英文摘要：

The dynamic mechanism of spatial-temporal evolution of regional service industry is an exploration for the evolution law of service industry,which is one of the important contents of service industry.At present,most of researches on the dynamic mechanism of evolution of service industry are about the interpretation of the effects of one or several factors on evolution of service industry.Based on service products theory,equilibrium theory,location theory and industrial agglomeration theory,we construct a theoretical framework for explaining the dynamic mechanism of spatial-temporal evolution of regional service industry by integrating three factors of supply-demand,spatial agglomeration-diffusion and government regulation from the two dimensions of time and space.Then,empirical analysis is made on the dynamic mechanism of spatial-temporal evolution of service industry in the Yangtze River Delta by applying the above-mentioned framework.The results indicate that spatial-temporal evolution of service industry in the Yangtze Delta results from the interaction of the three mechanisms,among which the mechanism of supply-demand plays a leading role,and the mechanism of spatial agglomeration-diffusion plays a certain role,especially in producer services and consumer services,and the mechanism of government regulation reflects the favorable influence on some services.
