基于1978~2005年的面板数据,以新古典经济增长理论为基础,运用广义C-D生产函数建立模型,对中国乡镇企业总产值增长率、技术进步率、各生产要素贡献率和不同时期(若干个“五年计划”)的总产值年平均增长率、技术进步率及各生产要素的年平均贡献率进行了全面测算和考察,并辅以“Chow检验”方法,对改制前后乡镇企业生产函数模型估计结果中相关参数的稳定性进行了检验。实证结果表明,目前乡镇企业的产出增长主要还是靠劳动、资本投入来拉动,特别是以高资本投入来推动,这一趋势近年来还在进一步加强。
Based on the panel data from 1978 to 2005 and based on the neoclassical economic growth theory, a generalized CD production function is used to establish a model to analyze the growth rate of China’s total output value of industrial enterprises, the rate of technological progress, the contribution rate of various factors of production, “Five Year Plan ”), the annual average rate of increase of the total output value, the rate of technological progress and the annual average contribution rate of each factor of production were all calculated and inspected, supplemented by the “Chow test ” method, The stability of the relevant parameters in the estimation of the production function model of the enterprise is tested. The empirical results show that at present output growth of township and village enterprises is mainly driven by labor and capital investment, especially with high capital investment. This trend has been further strengthened in recent years.
