最终需求对经济拉动效率的变化

【摘要】：本文利用更映加工贸易的非竞争型投入产出模型测算发现2002年到2007年最终需求对中国GDP的拉动效率有所下降,为分析其下降的原因,文章针对区域间投入产出表的特征,提出了一种改进的结构分解分析(SDA)方法.该方法将列昂惕夫逆矩阵分解为替代效应和制造效应,并分解出了各个区域对拉动效率下降的贡献.研究发现内资企业国内品增加值率下降和最终使用结构变化是最终需求对GDP拉动效率下降的主要原因,而外资企业产品对进口品的替代则有利于提高最终需求对经济的拉动效率.
[Abstract]:Based on the non-competitive input-output model of processing trade, this paper finds that the efficiency of final demand to China's GDP has declined from 2002 to 2007. In order to analyze the reasons for the decline, this paper aims at the characteristics of the inter-regional input-output table. An improved (SDA) method for structural decomposition analysis is proposed. In this method, the Leonidov inverse matrix is decomposed into substitution effect and manufacturing effect, and the contribution of each region to the decrease of pull efficiency is decomposed. It is found that the decline of domestic value added rate of domestic enterprises and the change of final use structure are the main reasons for the decline of GDP pull efficiency by final demand. The substitution of foreign enterprises' products to imports is helpful to improve the efficiency of the final demand to the economy.
