中文摘要：

基于中国1978～2012年的省级面板数据，采用检验后的超越对数生产函数的随机前沿模型，利用两套资本存量核算方法，对中国经济增长动力的来源及其时空特征进行分析，并对2008年金融危机的4万亿元投资政策进行了效率评价。研究结果表明，中国属于典型的投资主导型经济，资本投入是中国经济增长持续稳定的最主要来源，TFP贡献率呈现逐年下降的趋势；中国经济增长动力由改革开放初期的资本、劳动力和TFP三驾马车平衡拉动，形成了现阶段的资本投入与TFP反向角力态势；区域经济差距主要源于资本投入与TFP双重差异，但TFP差异是最重要因素；4万亿元经济刺激政策下中国经济复苏属于典型的“投资主导型复苏”，是以牺牲中国生产率为代价的，TFP在2008年后呈现断崖式下降，平均拉低中国TFP达0．23～0．32个百分点。

英文摘要：

This paper analyses the sources of China impetus of economic growth and its spatial and temporal characteristics using tested stochastic frontier translog production func- tion based on Chinese 1978~2012 provincial panel data, and evaluates the efficiency of four trillion investment policy on the financial crisis of 2008. Research result shows that： China＇s economy belongs to the economy led by typical investment, capital investment is the main source of economic growth in China, TFP contribution rate shows a declining trend year by year; The propulsion of China＇s economic growth changes from evenly pull by troika includ- ed capital, labor and TFP in prime of reform to reversed wrestle within capital and TFP at the present stage; the regional economic disparity mainly comes from capital input and TFP double difference, but the difference of TFP is the most important factor; four trillion eco- nomic stimulus policy in Chinese economic recovery is a typical investment led recovery, which is at the expense of Chinese productivity. TFP in 2008 presents a cliff drop, and pulls down the TFP as 0. 23~0. 32 percentage points in average.
