区域制造业经济增长差距的效率检验及政策调整——基于“新”新经济地理的视角

A Study on Efficiency Test and Policy Adjustments of Regional Manufacturing Economic Growth Disparities——A View from‘New’New Economic Geography

文章选择全要素生产率作为区域内企业集聚力与分散力合力的替代变量,从区域经济增加值和全要素生产率变动的角度构建了区域经济差距效率检验模型。研究发现:东中西之间的创新转移效应差距明显,中西部市场化水平相对于东部还有较大的改进余地,创新转移效应是缩小中西差距的主导因素;东部的技术进步效应变动明显大于西部,略大于中部,东中西三个区域都出现了技术效率效应为负的粗放式增长,西部的粗放程度要高于东中部,技术进步与规模效应变动是扩大东中西差距的主导因素。缩小区域市场化水平差距、技术差距和提高规模效率是现阶段政策调整的方向。

Selecting total factor productivity as a substitute variable for the resultant force of firm centripetal and centrifugal forces in the region, this paper constructs the mathematical model of efficiency test about the regional economic gap from regional economic added value and total factor productivity changes. We find that there is an obvious innovation transfer effect gap among three regions, and there is large room for improvement in the Midwest market level relative to that in east region, innovation transfer effect is the main reason to narrow the gaps between central regions and western region. The changes of the technological progress effect in eastern region are significantly greater than that in west region, slightly larger than that in central region. There is an extensive growth of negative technical efficiency effect in three regions, and the extensive degree of economic growth in western regions is more than that in eastern and central regions. Changes of technological progress effect and scale economies effect are the dominant factors in the expansion of three regions gap. At present, narrowing the regional market level gap, the technology gap, and improving scale efficiencies are the direction of policy adjustments.
