针对高新技术产业效率评价问题,在现有文献的基础上构建了改进的高新技术产业效率评价指标体系。针对指标体系之间存在信息重叠的问题,提出了PCA三阶段DEA模型,并对2012年中国28个省份的高新技术产业效率进行了实证分析。实证研究表明:中国各省份高新技术产业效率整体表现不容乐观;在区域上呈现从东南沿海到内陆地区逐渐递减的态势。 For the high-tech industry efficiency evaluation, based on the existing literature, an improved high-tech industry efficiency evaluation index system was constructed. In order to solve the problem of overlapping information systems, a three-phase PCA DEA model is proposed and the efficiency of high-tech industries in 28 provinces in China is analyzed empirically. Empirical studies show that: the overall performance of high-tech industries in various provinces in China is not optimistic; in the region, the trend of decreasing gradually from the southeast coast to the inland areas appears.
