多样化、专业化与地区经济增长
发布时间：2018-10-13 19:13
【摘要】：针对目前理论和实证界关于专业化与多样化的关系以及它们对地区经济增长的作用莫衷一是的现状,本文基于CES生产函数,引入市场交易效率、固定学习成本、专业化经济程度和多样化经济程度等参数,构建多部门数理模型,定性分析了地区多样化、地区专业化的演化及它们对经济增长的作用。然后,使用2008-2014年的地级市面板数据进行实证检验。与现有研究有较大区别,本文的一般均衡分析与实证分析结果表明:(1)地区多样化水平与地区专业化水平大小的对立与统一是由其所处的分工阶段与市场范围大小所决定的。随着地区的市场交易效率、专业化经济程度和多样化经济程度的提高以及固定学习成本的降低,地区所处结构由自给自足结构转变为完全分工结构,从而地区多样化水平与地区专业化水平大小的关系会由完全对立转变为完全统一。多样化与专业化的关系特征检验显示,2008-2014年我国东部沿海和中部地区的专业化水平和多样化水平大小普遍是统一的,而东北部地区和西部地区的专业化水平和多样化水平大小大体上是对立的。(2)地区多样化与地区专业化是并行不悖的,即多样化水平和专业化水平在地区经济发展历程中能够同时提高。实证检验表明,2008-2014年我国地级市整体的专业化水平和多样化水平存在着一个同时提高的趋势。(3)多样化和专业化对地区经济增长的作用具有两重性,只有在地区专业化基础上的地区多样化才能促进区域经济增长。当地级市专业化水平较高时,地区多样化会显著推动其经济增长,地区多样化水平每提高一个单位,其人均真实产出会提高0.28%;但是当在地级市专业化水平较低的情况时,地区多样化反而会抑制其经济增长,地区多样化水平每提高一个单位,其人均真实产出则显著下降0.033%。本文从一个新的分工视角解释了地区多样化与地区专业化演化的微观机理,并揭示出地区多样化与地区专业化对区域经济增长作用的两重性,它们对地区经济增长的作用是相辅相成的,缺一不可。
[Abstract]:In view of the current situation of the relationship between specialization and diversification and their role in regional economic growth, this paper introduces market transaction efficiency and fixed learning cost based on CES production function. Based on the parameters of the degree of specialization economy and the degree of diversification economy, this paper constructs a multi-sector mathematical model, and qualitatively analyzes the evolution of regional diversification, regional specialization and their effect on economic growth. Then, using the 2008-2014 prefecture-level city panel data for empirical testing. The results of general equilibrium analysis and empirical analysis show that: (1) the opposition and unity of regional diversification level and regional specialization level are determined by the stage of division of labor and the size of market scope. With the increase of market transaction efficiency, the degree of specialization and diversification of economy, and the decrease of fixed learning cost, the structure of the region has changed from self-sufficient structure to complete division of labor structure. As a result, the relationship between regional diversification level and regional specialization level will change from complete opposition to complete unity. The characteristic test of the relationship between diversification and specialization shows that the level of specialization and the level of diversification in the eastern coastal and central areas of China from 2008 to 2014 are generally uniform. However, the level of specialization and the level of diversification in the northeast and western regions are on the whole opposite. (2) Regional diversification and regional specialization go hand in hand, That is, the level of diversification and specialization in the process of regional economic development can be improved at the same time. The empirical test shows that the specialization level and diversification level of prefecture-level cities in China have a tendency to increase simultaneously from 2008 to 2014. (3) diversification and specialization have dual effects on regional economic growth. Only on the basis of regional specialization can regional diversification promote regional economic growth. When the specialization level of prefecture-level cities is high, regional diversification will significantly promote their economic growth. With each unit of increase in regional diversification level, the real output per capita will increase by 0.28%, but when the specialization level of prefecture-level cities is low, On the contrary, regional diversification will restrain its economic growth. With each increase in regional diversification level, the real output per capita decreases by 0.033. This paper explains the microcosmic mechanism of regional diversification and regional specialization evolution from a new perspective of division of labor, and reveals the duality of regional diversification and regional specialization on regional economic growth. Their role in regional economic growth is complementary and indispensable.
