An Empirical Study on Provincial Differences and Investment Performance in China's High-Tech Industries
将中国31个省份分为发达、中等发达和欠发达三类，分析区域差异和要素投入对高技术产业绩效的影响，发现不同区域在产出弹性和全要素生产率上存在显著差异。
Through the cluster analysis of current development situation on China's high-tech industries, 31 provinces in China are divided into three regions, namely the developed, medium- developed and under- developed provinces. By means of introducing the regional dummy variables, the following conclusions are reached through a performance analysis of regional differences and factor inputs in High- tech industries.(1) An obvious statistic difference of inputoutput performance among provinces is existed in China's high-tech industries: for the sum of output elasticity(items of the slope), medium- developed and under- developed provinces are lower than the developed provinces; but for the TFP and improvement of technology(items of the intercept), they are higher than the developed provinces.(2) The rank of size of output elasticity is listed as the follows: investment, RD personnel investment, output value of new products,exports(The under- developed provinces are negative and others arepositive) and RD internal funding(It is negative).Meanwhile, the following suggestions are put forward:(1) From the aspect of regions, the medium-developed provinces and under-developed provinces need to promote the development of high-tech industries to overcome the lower situation of the sum of input-output elasticity than the developed provinces from a strategic height of improvement of. technology(2) From the angle of factor inputs, we need to perform the following measurements to improve the environment of investment and financing, promote the formation of industry capital, to increase the efforts of the cultivation of innovative talents, to improve the use of efficiency of RD funds, to improve the degree of opening to the outside world and the foreign trade markets andto increase the intensity of development of new products.
