中国铁路提速后技术进步对产出贡献的测算

Contribution Calculation of Technological Progress to Output after China Railway Acceleration

选取我国铁路提速后1997-2007年间的相关数据,采用基于科布——道格拉斯生产函数的Solow余值法,将有限分布滞后模型和半参数回归模型引入计算模型,对数据进行拟合,计算得到铁路提速后技术进步、固定资本投入以及人力资本投入对产出的贡献率,并根据计算结果提出促进我国高速铁路建设的相关对策建议.

The relevant data are selected from 1997 to 2007,and Solow residual value method based on Cobb-Douglas production function is used. Finite distributed lags model and semi-parametric regression model are introduced into computational model through data regression,and the contribution on railway output from technological progress,fix capital investment and human capital investment is calculated. Some suggestions are proposed on promote the further development of Chinese high-speed railway according to the calculate results.
