【摘要】：在全球产业结构不断优化升级,产业形态逐渐由“工业型经济”向“服务型经济”转变的背景下,生产性服务业对经济增长的重要性日益凸显。我国生产性服务业在过去的十年成绩显著,但与发达国家相比仍然比较落后。国内近些年对生产性服务业的研究逐渐增多,但关注对象主要是区位要素投入、政府政策、历史条件等,较少从产业结构或者产业分布角度进行。因此本文从产业结构的外部性角度研究其对生产性服务业增长的影响,具有重要意义。论文重点从产业外部性角度,分析专业化(MAR外部性)和多样化(Jacobs外部性)通过创新作用于生产性服务业增长的影响机制,并提出专业化外部性与产业增长间存在非线性关系,多样化外部性对产业增长起促进作用,产业外部性对生产性服务业增长的影响存在经济发展水平和人力资本门槛三个假说。实证研究方面,选取了中国2004-2012年省级面板数据,采用动态面板模型与门槛模型相结合的方式,对三个理论假设进行验证。动态面板模型实证结果表明在全国样本范围内,专业化外部性与产业增长之间存在“U形”关系,当专业化程度较低时,不利于产业增长,而当专业化程度较高时,专业化外部性促进产业增长;多样化外部性有利于生产性服务业增长;分地区讨论中,专业化和多样化对不同地区生产性服务业增长的影响不同。基于需求和创新视角,采用经济发展水平和人力资本作为门槛变量的研究发现,专业化外部性对生产性服务业增长的影响存在经济发展水平门槛和人力资本水平门槛。只有在经济发展水平跨越高门槛值且人力资本水平跨越低门槛值时,专业化对生产性服务业增长的促进作用才能实现;多样化外部性对生产性服务业增长的影响只存在人力资本门槛,且其作用方向始终为正。
[Abstract]:Under the background of the continuous optimization and upgrading of the global industrial structure and the gradual transformation of industrial form from "industrial economy" to "service-oriented economy", the importance of producer services to economic growth is becoming increasingly prominent. China's producer service industry has made remarkable achievements in the past ten years, but still lags behind the developed countries. In recent years, the research on producer services in China has gradually increased, but the focus is mainly on the regional factors input, government policies, historical conditions, etc., and rarely from the perspective of industrial structure or industrial distribution. Therefore, it is of great significance to study the impact of industrial structure on the growth of producer services from the perspective of externality of industrial structure. From the perspective of industrial externality, this paper analyzes the externalities of specialization (Mar) and diversification (Jacobs) and points out that there is a nonlinear relationship between specialization externality and industrial growth through innovation. Diversification externalities promote industrial growth. There are three hypotheses on the influence of industrial externalities on the growth of producer services: the level of economic development and the threshold of human capital. In the empirical study, the provincial panel data from 2004-2012 in China are selected, and the dynamic panel model and threshold model are used to verify the three theoretical assumptions. The empirical results of dynamic panel model show that there is a "U-shaped" relationship between specialization externality and industrial growth in the national sample range. When specialization is low, it is not conducive to industrial growth, but when specialization is high, it is not conducive to industrial growth. Specialization externalities promote industrial growth; diversification externalities are beneficial to the growth of producer services; in the regional discussions, specialization and diversification have different effects on the growth of producer services in different regions. Based on the perspective of demand and innovation, it is found that the influence of specialization externality on the growth of producer services exists the threshold of economic development level and the threshold of human capital level by using the level of economic development and human capital as threshold variables. Only when the level of economic development exceeds the high threshold and the level of human capital crosses the low threshold can specialization promote the growth of producer services. The influence of diversification externalities on the growth of producer services has only the threshold of human capital, and its direction of action is always positive.
