【摘要】：本文利用更映加工貿(mào)易的非競爭型投入產(chǎn)出模型測算發(fā)現(xiàn)2002年到2007年最終需求對中國GDP的拉動效率有所下降,為分析其下降的原因,文章針對區(qū)域間投入產(chǎn)出表的特征,提出了一種改進(jìn)的結(jié)構(gòu)分解分析(SDA)方法.該方法將列昂惕夫逆矩陣分解為替代效應(yīng)和制造效應(yīng),并分解出了各個區(qū)域?qū)瓌有氏陆档呢暙I(xiàn).研究發(fā)現(xiàn)內(nèi)資企業(yè)國內(nèi)品增加值率下降和最終使用結(jié)構(gòu)變化是最終需求對GDP拉動效率下降的主要原因,而外資企業(yè)產(chǎn)品對進(jìn)口品的替代則有利于提高最終需求對經(jīng)濟(jì)的拉動效率.
[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.
