基于多水平发展模型的工业生产性服务外部化时空分异及影响因素研究

针对中国东部经济发达地区和西部欠发达地区工业生产性服务外部化同处高位的现象,基于2002、2007、2012和2017年中国地区投入产出表,采用HLM构建多水平发展模型,探索其动态演变趋势及行业、区域差异.实证结果显示:工业生产性服务外部化呈先下降后上升的U型动态变化趋势;外部化水平行业和区域间均存在显著差异,但其发展速度区域差异显著,行业差异不显著;市场规模、资本密集程度、生产性服务业发展水平、市场化等因素对外部化均存在显著影响.

Study of Spatial-Temporal Differences and Influencing Factors of Industrial Productive Service Externalization Based on Multilevel Development Model

In view of the phenomenon that industrial productive service externalization in eastern developed regions and western underdeveloped regions are both high, based on the 2002, 2007, 2012 and 2017 China input-output tables, a Multilevel development model is constructed to explore the dynamic changes of industrial productive service externalization and the difference between industries and regions. The result shows that:the externalization of industrial producer services shows a U-shaped dynamic change trend; there are significant differences between industries in externalization but not in its development speed, while both externalization and its development speed are significant different between regions; All of the factors such as market size, capital intensity, development of producer services, marketization have significant effect on Externalization.
