开放条件下制造业价值链攀升的影响因素研究——基于江苏制造业行业面板数据的分析

Research on the Impact on Manufacturing Value Chain Climbing under the Conditions of Opening——An Empirical Analysis Based on Jiangsu Manufacturing Industry Panel Data

开放条件下的制造业地区专业化、企业规模、外贸出口对其价值链攀升具有不同的影响和作用。文章以江苏制造业为例,利用主成分分析测度行业价值链攀升状况,进而运用静态、动态面板数据模型考察制造业行业的地区专业化水平、企业规模、外贸出口对其价值链攀升的作用机理。研究发现:企业规模的壮大有助于制造业价值链攀升,制造业价值链攀升与地区专业化、企业规模三者之间存在长期的均衡关系,但地区专业化对制造业价值链攀升并无明显的促进作用,长期看,外贸出口并不能实现制造业价值链攀升的目标。此外,制造业各行业对总体截距的偏离还具有劳动、资本和知识技术密集型产业倒置的现象。

The manufacturing regional specialization, enterprise scale and export have different impacts on the value chain climbing under the conditions of opening. Taking Jiangsu manufacturing for example, this paper uses the principal component analysis to measure industry value chain rising status, and static and dynamic panel data model to study the mechanism of regional specialization, enterprise scale, and exports impacting the value chain climbing. The study finds： the growth of enterprise scale contributes to manufacturing value chain climbing; there is a long-term equilibrium relationship among the manufacturing value chain climbing, regional specialization and enterprise scale, but regional specialization doesn＇t show promoting function to the manufacturing industry value chain climbing, and exports cannot achieve the goal of manufacturing value chain climbing. In addition, there is an inversion of labor, capital, knowledge and technology intensive industry in the manufacturing industrial deviation of the total intercept.
