摘要
文章利用匹配后的中国工业企业数据库和海关数据库,基于双向约束的Tobit模型,从产业关联视角实证检验了进口产品质量对产业出口升级的影响。研究发现:(1)一般贸易进口产品质量的提高,不仅提升其自身出口附加值率,并通过前、后向产业关联效应提升其上下游产业的出口附加值率,但加工贸易进口产品质量的提高却抑制了出口附加值率的提升;(2)产业间劳动力竞争和技术共享是影响进口产品质量前、后向产业关联效应的重要因素,产业间劳动力结构相似度越低、技术共享密切度越高,越有利于前、后向产业关联正效应的发挥;(3)基于动态分解的进一步研究发现,资源再配置是进口产品质量促进行业出口附加值率提升的重要途径,但主要体现在产业内部。据此,文章从优化进口、产业升级和完善国内市场机制等方面提出相应政策启示。
By matching the database of Chinese industrial enterprises with China customs database,this paper empirically examines the impact of imported products quality on the upgrading of industrial exports from the perspective of industrial linkage based on the Tobit model of two-way constraints.The research indicates that:(1)the improvement of the quality of imported products in general trade not only promotes their own export value added ratio,but also increases the export value added ratio of their upstream and downstream industries through the forward and backward industrial linkage effects.However,the improvement of the quality of imported products in processing trade inhibits the improvement of export value added ratio;(2)the labor competition and technology sharing among the industries are the important factors affecting the forward and backward industrial linkage effects of imported products quality.The lower the similarity of labor structure and the higher the closeness of technology sharing among the industries,the more favorable the positive effect of the forward and backward industrial linkage;(3)based on the further research of dynamic decomposition,it is found that resource reallocation is a significant way for imported products quality to promote export value added ratio of the industry,but it is mainly reflected in the interior of the industry.Accordingly,this paper puts forward the corresponding policy enlightenments from the aspects pf optimizing import,upgrading industry and improving domestic market mechanism.
