中国地区信息资源产出技术进步与效率研究

Research on Technical Progress and Efficiency of Regional Information Resource Productivity in China

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。

Taking the information resource infrastructure and labor as input factors, the turnover of post and telecorn as output factor, this paper analyzes information resource productivity efficiency base on Data Envelopment Analysis （DEA） combine with Malmquist Index Analgsis in recent years. The result shows that technical progress plays an important role and each area achieves much. The scale efficiency is improved and almost all areas are of increasing returns to scale. The pure technical efficiency is stable and the efficiency gap isn＇t large in different provinces. Technical efficiency has no relation with GDP. The total factor productivity increases because of the contributions of technical progress and scale efficiency in most provinces in China.
