利用信息资源基础设施指数和劳动力作为投入变量,邮电业务额作为信息资源产出替代变量,运用DEA方法结合Malmquist指数分析我国近几年的信息资源生产效率。结果表明,技术进步在信息资源生产中具有非常重要的作用,各地区技术进步显著,并且比较均衡。规模效率有所提高,几乎所有地区都处于规模报酬递增阶段,增加规模可以提高效率。全国纯技术效率相对稳定,并且东、中、西部地区的规模效率和纯技术效率的差距并不明显。由于技术进步和规模效率的贡献,绝大多数省市全要素生产率有所提高。
Using information resources infrastructure index and labor force as input variables, postal service volume as output variable of information resources, using DEA method combined with Malmquist index to analyze China’s information resource production efficiency in recent years. The results show that technological progress plays a very important role in the production of information resources. The technological progress in all regions is significant and balanced. Scale efficiency has improved, almost all regions are in the stage of increasing returns to scale, increase the scale can improve efficiency. The pure technical efficiency of the whole country is relatively stable, and the difference between the scale efficiency and the purely technical efficiency in the eastern, central and western regions is not obvious. Due to the contribution of technological progress and economies of scale, the total factor productivity of the vast majority of provinces and cities has been raised.
