文章运用我国投入产出表数据计算了工业行业垂直专业化程度指标,并对影响我国工业行业参与国际垂直专业化程度的相关因素进行了实证分析。结果表明:比较优势及比较优势差异度是影响我国工业行业参与国际垂直专业化分工程度的重要基础因素;随着关税等贸易壁垒的进一步降低,我国工业行业参与国际垂直专业化的程度不断加深;关税等贸易壁垒的降低使外向度高的行业参与国际垂直专业化程度较外向度低的行业更加深入;相对于劳动密集型行业而言,国际垂直专业化分工在资本相对密集的行业中的规模经济强化程度更为显著。
The article calculates the index of vertical specialization in the industrial field by using the input-output data of China and empirically analyzes the related factors that affect the participation of the industrial field in the international vertical specialization. The results show that: the comparative advantage and the degree of comparative advantage are the important basic factors that affect China’s industrial participation in the international vertical specialization; with the further reduction of trade barriers such as tariffs, the degree of China’s industrial participation in international vertical specialization is deepening; The reduction of trade barriers such as tariffs will make the industries with high degree of outward participation participate more in the industries with the lower degree of verticalization than those with less outward industries. Compared with the labor-intensive industries, the scale of the international vertical specialization in the relatively capital-intensive industries The degree of economic reinforcement is even more pronounced.
