京津沪知识密集型服务业技术进步贡献率的测算

Estimate on Technology Progress Contribution Ratio of Knowledge Intensive Service Industry in Beijing,Tianjin and Shanghai

知识密集型服务业具有高知识性、高技术性、高互动性、高创新性、高附加值性、强渗透与强辐射性等特点,它将是我国未来经济新的增长点和经济新动能的重要来源。本文以北京、天津、上海的知识密集型服务业为研究对象,比较了2004～2016年这三个直辖市知识密集型服务业的增加值及其占GDP的比重、从业人员数量以及其内部各行业增加值的发展趋势;运用C-D生产函数测算了这三座城市12年间知识密集型服务业的技术进步贡献率,并针对京津沪发展知识密集型服务业提出了对策建议。

Knowledge Intensive Service Industry(KISI)possesses the characters of high knowledge,high technology,high interaction,high innovation,high added value,strong penetration and strong radiation,it will be the new economic growth point and important part of new kinetic energy economy in China.This paper take KISI of Beijing,Tianjin and Shanghai as research objects,compared the development trend of their added value,the ratio of GDP,number of employee and the added value of each industry inside them from 2004 to 2016,then calculated the technology progress contribution ratio of them by C-D production function,finally put forward some advice for the development of three city’s KISI.
