中国加工出口的产业关联效应和波及效应——基于针对加工贸易之非竞争型投入产出表

Industry Relevance and Industry Spreading Effect of China's Processing Export Based on the Non-competitive Input-output Table for Processing Trade

加工出口生产中,中间投入占比较高,因而增加值率较低,但正逐步改善;国内中间投入占比偏低,因此其对国内上游产业的带动能力仍然有限,但正逐步增强;加工出口生产的影响力明显低于国内使用产品生产和非加工出口生产,但其影响力正逐渐增大;由于全部加工出口产品在总产出中的占比有限,所以除个别部门外,加工出口生产对各部门的产业关联特性和产业波及特性均没有根本影响。

In the production of processing export, the intermediate input takes a large proportion so its value-added rate is low, but is gradually improving; the domestic intermediate input has a lower proportion, so its capacity to promote the domestic upstream industry is still limited, but is gradually increased; the proportion of the product of processing export in total output is small, so apart from individual departments, the production of processing export has no fundamental impact on the characteristics of industry relevance and industry spreading of the various departments.
