以江苏省工业39个细分行业统计数据为基础,采用数据包络分析基础上的曼奎斯特指数方法(DEA-Malmquist)测算和比较江苏省2002-2007工业各细分行业全要素生产率。研究发现:总体上江苏省工业行业TFP增长率呈下降趋势,平均增长率为7.6%,对工业增加值增长的贡献平均达到27.9%;经过分解,技术进步和规模效率的改善对产出增长的贡献更加突出,而纯技术效率成为阻碍TFP增长的薄弱环节;同时,2002-2007年间江苏省工业TFP增长率相对较高的行业集中在垄断程度较高的行业,而资本密集型工业TFP增长率也低于劳动密集型工业。
Based on the statistics of 39 industries in Jiangsu Province, the DEA-Malmquist method was used to calculate and compare the total factor productivity of each industry in Jiangsu Province from 2002 to 2007. The study finds that: Overall, the TFP growth rate of industrial sectors in Jiangsu Province shows a downward trend, with an average growth rate of 7.6%, contributing an average of 27.9% to the added value of industrial added value. After decomposition, improvements in technology and economies of scale, While the contribution of pure technology has become a weak link that hinders the growth of TFP. Meanwhile, the industries with relatively higher TFP growth rates in Jiangsu Province concentrated in industries with a higher degree of monopolization in 2002-2007, while the growth rate of capital-intensive industries TFP Also lower than labor-intensive industries.
