【摘要】：随着经济全球化的不断深入发展,国际贸易经历了从产业间、产业内发展到现今产品内的历程,不同的阶段所承载的分工形式也逐步从产品分工发展到如今的要素分工即垂直专业化分工。垂直专业化在其他分工形式的基础上更加细化、深入、多层次,这一分工模式为世界各国的经济发展和经济合作带来了全新的视野。我国作为世界贸易第一大国,参与垂直专业化的程度日益加深,因此深入分析我国参与垂直专业化的经济效应尤为重要。上个世纪90年代垂直专业化迅速发展,引起了国内外学者的关注。垂直专业化分工与以往分工不同的方面在于,它是深入到产品内部的分工模式,将比较优势分解到不同生产工序上,进而延伸出具有这类比较优势的国家专门生产该环节的分工模式。不同的产品生产具有不同的最佳规模和最佳投入,同样不同的生产环节也在最有效的规模和投入上各有分别。垂直专业化以更有效的资源配置和更精准的规模进行生产,提高了世界经济总体福利水平。本文对2002年至2012年我国20个工业部门垂直专业化比率进行测算,并通过实证分析了垂直专业化对这些行业生产率的影响,研究了不同行业之间存在的差异,对二者之间的联系进行了详细的解释。本文的结论认为,首先对于工业行业总体垂直专业化提高了生产率水平,并且这种提高大多是通过技术进步来完成的；其次垂直专业化对生产率的促进作用略强于研发投入的促进作用；最后对于出口外向度和资本密集型的行业来说,垂直专业化对生产率的促进作用更大,而对于市场平均规模较高的行业,垂直专业化对生产率的促进作用则小于研发投入。根据上述结论,我国在参与垂直专业化的过程中要注意对不同的行业进行相对应的引导,同时企业自身仍要重视自主创新,提高自身技术能力,更好的参与国际分工。
[Abstract]:With the deepening development of economic globalization, international trade has experienced a process from inter-industry, intra-industry development to current product development. The forms of division of labor carried by different stages have gradually developed from the division of labor of products to the division of elements of today's division of labor, that is, vertical division of labor. Vertical specialization is more detailed, in-depth and multi-level on the basis of other forms of division of labor. This pattern of division of labor has brought a new vision to the economic development and economic cooperation of all countries in the world. As the largest country in world trade, China is becoming more and more involved in vertical specialization. In -10s, the rapid development of vertical specialization has attracted the attention of scholars at home and abroad. It is a division of labor model that goes deep into the product and decomposes comparative advantage into different production processes. Thus extending the division of labor in countries with such comparative advantages to produce this link. Different products have different optimal sizes and inputs. The same different production links differ in terms of the most effective scale and input. Vertical specialization produces on a more efficient allocation of resources and on a more accurate scale. From 2002 to 2012, the vertical specialization ratio of 20 industrial sectors in China is measured, and the impact of vertical specialization on the productivity of these industries is analyzed empirically. This paper studies the differences between different industries, and explains the relationship between them in detail. The conclusion of this paper is that, firstly, vertical specialization of industrial industries improves the productivity level. And most of this improvement is achieved through technological progress; second, vertical specialization promotes productivity slightly more than R & D investment; finally, for export-oriented and capital-intensive industries, Vertical specialization contributes more to productivity, while for industries with higher average market size, vertical specialization contributes less to productivity than R & D. In the process of participating in vertical specialization, our country should pay attention to the corresponding guidance to different industries, at the same time, enterprises should still attach importance to independent innovation, improve their own technical ability, and better participate in the international division of labor.
