Abstract: The paper provided a model framework to differentiate industry clustering. By applying Solovian growth accounting methodology, the study investigated geographical concentration of production factors and increasing return to scale in State-level Science and Technology Industrial Parks in China. Result shows that there was industry clustering in the Zones. However, much attention should be paid to the zones with poor agglomeration quality.

Key words: science and technology industrial parks, industry cluster, production factor, increasing return to scale

摘要： 基于对国家高新区产业集聚内涵的界定，本研究引入带有科技进步的柯布道格拉斯生产函数，从生产要素的地理集中及其规模收益递增入手，通过构建产业集聚判定的模型框架，对其产业集聚现状进行了实证研究。研究结果表明，国家高新区的产业集聚已具雏形，但部分高新区产业集聚质量不高的问题仍应引起足够重视。
