区域信息化与劳动生产率相关关系的实证分析

The positive analyse between the regional informatization and the labour productivity

本文首先定义了衡量区域信息化发展水平的信息化发展指数与衡量区域劳动生产率指标的比较劳动生产率。随后,采用最新的统计数据对二者进行相关分析,发现中国各区域的劳动生产率与信息化发展呈现出极强的区域不平衡性,且信息化发展的区域不平衡性更强,而同区域的信息化发展指数与比较劳动生产率则呈现出较强的相关性,其中第三产业最为明显。最后采用葛兰杰因果关系检验方法进一步确定,在信息化与劳动生产率的互动关系中,信息化为“因”,劳动生产率为“果”。

This paper firstly define the IDI （informatization development index）to evaluate the informatization level of the region,and define the CLP（ comparative labour productivity）to evaluate the work efficiency of the region. Subsequently,this paper use the new statistics data to analyse the correlative relation between the two indexes, find that there are imbalanced phenomenon among regions in China＇ s labour productivity and the informatization development. At the same time, the correlation between the labour productivity and the informatization development in a same region is evident. At last,use the Granger causality test method,find that the informatization is the Granger causality of the labour productivity.
