建筑业技术进步贡献率测算模型与实证研究

The Calculation of Contribution Rate of Technique Progress in Construction Industry based on Integrated Arithmetic

建筑业是我国国民经济支柱产业之一,分析其技术进步对产业产值的贡献率,对引导建筑业健康发展有重大意义。本文在原有理论研究的基础上,以生产前沿面理论作为理论基础,以参数估计和非参数估计相结合的手段,以我国十九个省市的建筑相关数据为样本,计算出我国1996-2003年建筑业技术进步贡献率。其计算结果表明技术进步对建筑经济增长的贡献率较小;同时也表明技术进步贡献率的波动具有周期性。

Construction industry plays an important role in economy.It is critical to analyze the contribution rate of technique progress to economy,which can steer construction industry to the path of health growth.The theory of production leading foreland is used as academic foundation.The paper combines parameter estimate with non-parameter estimate and further calculates the contribution rate of technique progress from 2000 to 2001 by data related to construction industry in 20 provinces or cities.Results of calculations indicate that the contribution rate of technique progress is lowest and that the fluctuation of the rate is periodical.
