Abstract:

Based on the micro-spatial data perspective of Japanese enterprises in Japan, according to the type of industry of the parent company, we compare and analyze spatial agglomeration/distribution situation and evolution trend of enterprises in different industries, and use the DO index to measure the range of agglomeration distances in Beijing.Results found that:(1) under the condition of "pure distance", the concentration scale of raw material-intensive manufacturing is 35-60km, the concentration scale of capital and technology-intensive manufacturing is 20-28km, and the concentration scale of productive service industry is 10-18km, and the spatial distribution of life service industry is relatively random; under the conditions of considering the size of the enterprise, the scale of agglomeration of various industries is quite different, and the agglomeration (distribution) index is significantly increased; (2) Between service industry and manufacturing industry exist obviously the mutual exclusion phenomenon,which is not significant for the manufacturing industry, but there is a clear mutual exclusion for the service industry, and the mutual exclusion scale occurs at 22-28km; (3) With the pass of time, the spatial distribution pattern of raw material-intensive manufacturing industries has basically stabilized, and capital- and technology-intensive manufacturing new-old enterprises have become more and more concentrated in space, and the copolymerization scale has occurred at 18-30km.The distribution pattern of new-old enterprises in the production service industry and the life service industry is basically similar. The newly-relocated enterprises rely on the enterprises that have settled in the previous period, and are exposed to spread, close to the distribution, and tend to cohesion in space.

摘要：

基于驻京日企微观空间数据，根据企业母公司所属行业类型，对比探析不同行业企业的空间集聚/分散态势及其演化趋势，利用DO指数法，科学测定在京日企空间集聚范围。研究发现：（1）在“纯距离”条件下，原材料密集型制造业集聚尺度为35-60km，资本和技术密集型制造业集聚尺度为20-28km，生产性服务业的集聚尺度为10-18km，而生活服务业空间分布则较为随机；在考虑企业规模条件下，各个行业集聚尺度则大相径庭，集聚（分散）指数显著升高；（2）服务业与制造业之间存在明显的互斥现象，对于制造业而言互斥状态并不显著，但对于服务业而言在空间上与制造业存在明显的互斥现象，且互斥尺度发生在22-28km上；（3）随着时间的推移，原材料密集型制造业在空间上的分布模式基本趋于稳定，资本和技术密集型制造业新-老企业在空间上愈发集聚，共聚尺度发生在18—30km范围内；生产性服务业与生活服务业的新-老企业分布模式基本相似，新入驻企业依托于前期入驻企业，接触扩散、就近分布，在空间上趋于共栖。
