中国经济增长质量与增加值率变动分析

Analysis of China's Economic Growth:Quality and the Changes in Value Added Rate

增加值率是从宏观上度量一国经济投入产出效益和增长质量的综合指标。中国的增加值率在下降,反映了经济增长的质量在下降。中国的增加值率与美国、日本等发达国家相比存在着较大差距,既是由于产业结构的差距所致,也是由于产业增加值率的差距所致。2002年以来我国产业结构的变动趋势是工业变重,服务业变轻,使得经济增长质量变得更差。我们分析了产业结构、产业增加值率变动对总体增加值率的影响,认为通过加快第三产业的发展、利用技术进步和技术改造提高产业增加值率,把我国的增加值率提高到中等发达国家的水平是有可能的。

Value added rate is a comprehensive indicator which measures input-output effect and quality of economic growth at the macro level.China's decreasing value added rate indicates a decline in its economic quality growth.In fact,there is a big gap between China's value added rate,and that of developed countries such as the U.S.and Japan.Since 2002,China's industrial structure has changed and the industry tends to be more emphasized while the service industry is not,which worsens the growth quality of its economy.This paper analyzes the influences of changes in industrial structure and industrial value added rates on the overall value added rate.It is believed that by speeding up the development of the third industry and increasing the industrial value added rate through technological advances and innovation,it is possible to raise China's value added rate to that of moderately developed countries.
