摘 要:在采用虚拟变量对密度函数进行调整的基础上,借助扩展方法引入时间变量构建计量经济模型测度北京零售业空间发展的分异与趋势,并利用GIS技术研究了新型零售业的空间布局特征。结果表明:①1984-2010年,近郊区零售业保持着强劲的增长势头,增速是远郊区的近两倍,而远郊区快于中心区,说明中心区零售业地位的相对下降,类似于20世纪中期美国大都市区的发展特征。②2000年以来,远郊区零售业增速下降,近郊区小幅提升,而中心区发展速度明显回升,说明部分学者提出的20世纪90年代末期旧城区零售业"空洞化"、"边缘化"的发展趋势并未延续。③紧随人口的郊区化,90年代中期兴起的连锁超市以三环路为基础外向发展,三、四环路和五、六环路之间数量较多,而传统百货商店则主要布局在三环路以内。④以超市为代表的新型零售业空间布局呈现大分散、小集聚的特征,没有表现出明显的等级性,集聚区域既包括近郊人口密集区,也包括远郊新城和城郊大型居住区。零售业的空间发展趋势与超市的空间特征共同显示,北京应进一步提升远郊零售业的连锁化水平,提高服务水平和质量,促进居住与消费的空间平衡。Retailing in Beijing has experienced rapid change in the reform era, and has become an important engine driving the economy. However, there has been little systematic analysis of the retail structure change until recently. It was found beneficial to replace the distance-to-CBD variable by a set of dummy variables in the density functions which are widely used to analyze population and employment distributions. With the aids of the expansion methods of model construction, we formulate econometric model to measure the development of retailing structure change in metropolitan Beijing by the introduction of time variable. It is shown that the greatest growth rate in retail trade has occurred in the inner suburbs, and it is almost twice that of the outer suburbs. The growth rate is the lowest in core urban area. So, there is a relative decline of retail share in urban center, similar to the suburbanization of retail in American metropolitan areas. Since 2000, the pace of development in urban center has increased, and it has dropped in outer suburbs. It is contradictory with the previous notions of "downtown retailing vacuum". Based on GIS spatial analysis methods, the paper illustrates spatial structure of supermarkets in metropolitan Beijing. It demonstrates that following the population suburbanization, the supermarkets are mainly diffused to outside the third ring road while the full-line department stores are mainly located within the third ring road. More domestic supermarkets have been built between the fifth and sixth ring roads and foreign or joint-venture supermarkets are distributed between the third and fourth ring roads. It also indicates that the supermarkets in Beijing have obvious characteristics of spatial concentration including some new towns in the outer suburbs and the large-scale residential areas, but there is no obvious hierarchical structure with retailing and services centers. This study suggests that retail chains in the outer suburbs should be improved.
