中间品关税减让、契约制度与全要素生产率

The Tariff Reduction of Intermediate Goods,Contract System and Total Factor Productivity

随着对外开放的不断加深,我国经济经历了持续的高速增长,国内企业的全要素生产率(TFP)也在不断提高。在理论模型和计量模型建立的基础之上,运用中国工业企业库的数据作为样本,对全要素生产率的影响因素进行计量检验,并着重考察中间品关税减让、契约制度对全要素生产率的影响。在从国际经济学和制度经济学两个研究角度的综合分析中,得出结论:中间品关税减让对本国全要素生产率的提高有正向作用;在制度保障更为完善的地区对企业全要素生产率的提高作用更为明显。因此,对中国对外开放来说,通过完善契约执行等制度体系,可以更为有效地发挥市场开放对企业竞争力的提升作用。

With the expanding of opening up, China experienced a rapid economic growth and China firms＇ total factor productivity （TFP） is rising constantly. On the basis of theoretical and econometric models, the paper uses the Chinese industrial enterprise library data as samples. Then we empirically examine the causes of productivity changes while accounting for the effect of the tariff reduction of inter- mediate goods and contract system on total factor productivity. After a comprehensive analysis from In- ternational Economics and institutional economics, we made the following conclusion： the tariff reduc- tion of intermediate goods would improve China firms＇ total factor productivity; the improvement would be more obvious in a area with more prefect contract system. So, it is more effective for China to open up the market to enhance the competitiveness of enterprises by improving the system of contract execu- tion and so on.
