西安市科技创新能力及其绩效评价

Science and Technology Innovation Capability and Its Performance Evaluation of Xi'an City

依据2005—2014年西安市科技创新的面板数据,运用综合权重TOPSIS法分析西安市的科技创新能力,采用BCC模型、超效率DEA模型与Malmquist指数分析西安市的科技创新绩效。研究结果表明:2005年以来,西安市科技创新的投入能力、产出能力与综合能力均呈现逐年提升的变化趋势,而科技创新的绩效水平呈现先下降后上升的变化趋势,除2010年外,西安市的科技创新均为DEA有效,科技创新能力与效率之间的协调发展关系呈现逐年改善趋势。当前,西安市的科技发展仍然处于粗放型的增长方式,导致科技创新全要素生产率下降的主要原因是技术效率与规模效率下降,技术进步对科技发展具有一定的促进作用。

This paper uses the comprehensive weight TOPSIS method to analyze the scientific and technological innovation abiliW of Xi＇an based on the panel data of Xi＇an＇s science and technology innovation from 2005 to 2014. Then the paper uses the BCC model, the super efficiency DEA model and the Malmquist index to analyze the performance of Xi＇an＇s science and technology innovation. Results show that since 2005, the input capability, the output capability, the comprehensive capability of Xi＇an＇s science and technology innovation are presented ascending trend year by year, while the performance level of science and technology innovation presents the trend of first decrease and then rise. Except 2010, Xi＇an＇s science and technology innovation are effective DEA, and the harmonious development between the abihty and efficiency of science and technology innovation presents the trend of improving year by year. At present, Xi＇an＇s science and technology development is still in the extensive mode of growth. The main reasons for the decline of total factor productivity of science and technology innovation are the decline of technical efficiency and scale efficiency, while the technological progress has a certain role in promoting the development of＇science and technology.
