天津市服务业技术进步贡献率的测算与分析

Calculation and Analysis on Contribution Rate of Technological Advance of Service Industry in Tianjin

利用天津市1978—2006年的时间序列数据,估算了天津市服务业的资本存量;以此为基础,应用广义最小二乘法(GLS)对C-D生产函数进行回归分析,测算并分析了天津市服务业技术进步贡献率。得出如下结论:天津市服务业的技术进步贡献率仍然较低,服务业发展处于资本驱动阶段。最后提出促进服务业的健康协调发展、提高技术进步贡献率的对策建议。

Using the time series during 1978-2006 data about service industry in Tianjin, this paper estimates the capital deposit of service industry in Tianjin. On the basis of the above analysis,it analyzes the C-D production function by GLS,and measures the contribution rate of technological advance of service industry in Tianjin. It draws the conclusions that the contribution rate of technological advance of service industry in Tianjin is still rather low,and service industry in Tianjin is driven by capital. Finally, it puts forward some countermeasures for promoting the healthy development of service industry and increasing the contribution rate of technological advance.
