技术进步对辽宁省建筑业经济增长的影响

Impact of technological progress on Liaoning’s economic growth in the industry of construction

针对辽宁省建筑业经济高速增长的现状,采用科布.道格拉斯生产函数和索罗增长模型,测算了辽宁建筑业各生产要素对经济增长的贡献率。结果表明:资本投入对建筑业经济增长的贡献率高达80.75%,而同期技术进步贡献率仅为7.59%,且资本投入的产出弹性远高于劳动投入的产出弹性,辽宁省建筑业还处于外延式增长阶段。

In view of the rapid economic growth in the industry of construction in Liaon-ing, Cobb-Douglas production function and Solow growth model were applied to calculate the contribution rate of investment to economic growth in Liaoning＇s industry of construc-tion. Results show that the contribution rate of capital investment to economic growth of construction industry is up to 80.75%, but the contribution rate of technological progress is only 7.59% in the same period, and the output elasticity of capital input is far more than that of labor input, which indicates the construction industry in Liaoning is still at epitaxi-al growth stage.
