北京高技术制造业多中心结构演变特征与地区全要素生产率的空间分布

Spatial Matching of Polycentric Structure Evolution and Regional Total Factor Productivity of Beijing High-tech Manufacturing Industry

以北京乡镇街道为最小空间单元,分析北京高技术制造业的空间演变特征,并采用增长核算法估算了170个乡镇街道的全要素生产率增长变化情况。研究发现:北京高技术制造业出现郊区化现象,且呈多中心结构分布在中心城区外围的近郊地区;全要素生产率增长率分布呈圈层结构,但增长率最高的中间圈层与高技术制造业的主要集聚地不匹配;北京高技术制造业的空间演变趋势与全要素生产率分布比较一致,高技术制造业空间结构仍没有达到均衡,有进一步向外围迁移的动力。

Manufacturing of Beijing has gradually withdrawn from the central city,whether the same trend in high-tech manufacturing, how to re-layout is more conducive to enhance the efficiency of the industry. This paper analyzes the spatial evolution characteristics of high-tech manufacturing industry in Beijing by qualitative and quantitative methods,then uses the growth algorithm to estimate the total factor productivity growth of 170 township streets in Beijing, and compares with the spatial evolution trend of high-tech manufacturing industry. The study found that Beijing’s high-tech manufacturing industry appeared suburbanization phenomenon, and was polycentric structure distributed in the outskirts of the outskirts of the city area. Total factor productivity growth is fragmented, but the highest growth rate of the middle circle does not match the main concentration of high-tech manufacturing. The spatial evolution trend of Beijing high-tech manufacturing industry is consistent with the distribution of total factor productivity, which shows that the spatial structure of high-tech manufacturing industry in Beijing still does not reach equilibrium and has the power to further migrate to the periphery.
