企业“扎堆”、技术升级与经济绩效 ——对中国开发区产业集聚的性质及其变迁的实证分析[Firm Concentration, Technology Promotion and Economic Performance: An Empirical Study on the Nature and Dynamics of Industrial Clusters in China’s Development Zones along the Down Reaches of Yangtze River]

Based on micro-firm data of development zones in Jiangsu Province along the Yangtze River, the effects of local factors special to development zones and of technology promotion on firm’s performance are tested, from which we try to illustrate the nature and dynamics of industrial clusters built on development zones. The results show that the primary reasons firms locate into development zones are not clustering benefits in general meaning brought by interactions among firms locally concentrated, but are the attraction of “policy rents” and the scale economy of infrastructure brought by government behaviors. Once located in the zone, the firm is doom to interact with local government as well as industry-related factors, and the clustering effects may emerge. Thus, the key to keep development zones’ competition sustainable, when governments’ bidding wars and policy adjustment fade away “policy rents” and scale economy of infrastructure, is to cultivate clustering effects.
