根据信息资源利用的深度,构建中国信息经济的分析框架,认为中国目前处于信息社会的初级阶段。然后选取资本、劳动力、信息资源作为投入变量,经济发展水平作为产出变量,采用DEA与Malmquist指数测度中国信息经济的技术效率与技术进步,并进一步研究投入要素的利用效率。研究结果表明,纯技术效率的地区差距不大,规模效率较低地区以西部地区为主,技术效率较低地区也以西部地区为主;技术进步东部地区与中、西部地区差距明显,最终导致了全要素生产率东部地区要高于中、西部地区;信息资源的利用效率西部地区明显比东、中部地区低;信息资源的利用效率最高,其次是劳动力,最后是资本。
According to the depth of the utilization of information resources, we construct the analytical framework of China’s information economy and think that China is currently in the initial stage of the information society. Then we select capital, labor force and information resources as input variables and economic development level as output variables. We use DEA and Malmquist index to measure the technical efficiency and technological progress of China’s information economy and further study the utilization efficiency of input factors. The results show that there is not much difference between purely technical efficiency in the region and in the western region with low efficiency and low efficiency. In the eastern part of China, The total factor productivity is higher in the eastern region than in the middle and western regions. The utilization efficiency of information resources is obviously lower in the western region than in the eastern and central regions. The utilization efficiency of information resources is highest, followed by the labor force, and finally, the capital.
