中文摘要：

把国家高新区集聚效应细化为要素集聚效应、人才集聚效应、创新集聚效应、生产力促进效应四个维度,以高新技术企业为主要比较对象,运用配对样本均值t检验,基于2007-2010年的统计数据对国家高新区集聚效应进行了实证研究。研究结果显示：在各个维度上,高新区企业均明显优于比较对象,国家高新区集聚效应十分显著,对区内企业发展起到了重要支持作用。但各高新区存在个体差异,在发展中宜区别对待。

英文摘要：

Through discomposing agglomeration effects of national high - tech zones into four dimensions, including factor ag- glomeration effect, talents agglomeration effect, innovation agglomeration effect and productivity promotion effect, we have an em- pirical study on agglomeration effects of national high- tech zones, using statistical data between the year 2007 to 2010 with the method of paired - samples t - test, and having the high - tech enterprises as the main comparative object. ]t is found that nation- al high -tech zones have significant agglomeration effects in each dimension, and they have played a key role in promoting the development of enterprises in the zones. At the same time, all the development zones have different agglomeration effects in each dimension, therefore they should be given different treatment in practice.
