中国建筑业全要素生产率及其收敛趋势

Total factor productivity for Chinese construction industry and its convergence trend

基于Malmquist指数法,分析了中国建筑业TFP的变化趋势和区域差异,并对建筑业TFP的发展趋势进行了σ收敛、β收敛和"俱乐部"收敛检验。结果证明,中国建筑业TFP总体上在提高,其主要动力是技术进步,各地区建筑业TFP的空间分异较为明显。σ收敛显示近年来中国建筑业TFP差距呈现出先缩小后扩大的趋势。β收敛则显示无论分时间段还是整个样本期间建筑业TFP均呈现出明显的收敛趋势,"俱乐部"收敛检验则只在东部和中部得到了验证。

Based on the Malmquist index method, the paper analyses the trend and the discrepancy of total factor productivity in Chinese construction industry, and verifies the convergence trend of TFP by using σ-convergence test, β convergence test and ＂club convergence＂ test. It finds that TFP of Chinese construction industry mainly arises in the period and its main drive is technical development,furthermore ,there are spatial differences among the provinces. σ-convergence test shows that the gap of TFP in Chinese construction industry became lower firstly and then increased in the end. β-convergence test reveals that not only analyzed by stages but also taken the period as a whole TFP takes on a convergence trend,however, ＂club convergence＂ test is significant only in the East and Middle regions.
