沪苏浙建筑业技术进步贡献率的计量与比较

The Measure of Technological Progress’s Contribution of Jiangsu Construction Industry Compared with Shanghai and Zhejiang

从技术进步的含义出发,在C-D生产函数和索洛余值的基础上,利用回归分析得出江苏、上海和浙江的资本弹性系数和劳动力弹性系数,进而分别计算和比较了三个地区建筑业经济增长中的年技术进步贡献率和各年相对于1995年的技术进步系数。主要结论:江苏省建筑业基本处于规模效益不变的阶段,上海市建筑业处于规模效益递减的阶段,浙江省建筑业处于规模效益递增的阶段;以1995-2003期间年均技术进步贡献率排序的话,为江苏(2.096%)、上海(0.898%)和浙江(0.683%)。研究结果表明,苏沪浙建筑业的经济增长质量不容乐观。

In order to build an innovative construction industry, it is important to firstly measure the current technological progress＇s contribution of Jiangsu Construction Industry. Beginning at the meaning of technological progress, this paper calculates the capital elasticity factor and manpower elasticity factor of Jiangsu, Shanghai and Zhejiang based on C-D function and Solow Remain. Then, it calculates the technological progress＇s contribution of these three districts. The main conclusion is that Jiangsu is at the stage of scale invariability, and Shanghai is at the scale decreasing stage, and Zhejiang is at the stage of increasing scale. Moreover, from the perspective of annual average technological progress＇s contribution, the ranking is Jiangsu （2. 096%）, Shanghai （0. 898%） and Zhejiang （0. 683%）. It is worried that the increasing quality of three districts＇ construction industry are not very good.
