【摘要】：以北京市城六区生产性服务业各行业为例,对生产性服务业空间集聚适度性进行评价,首先利用区位熵指数对其集聚规模进行测度,在此基础上利用突变级数法来研究集聚效率,通过集聚规模和集聚效率的对比,判断城六区生产性服务业各行业是否处于集聚适度范围,进而检验城六区各生产性服务业行业是否还未发生显著集聚效应,或者已经集聚适度甚至过度。结果表明:以北京市城六区为代表,生产性服务业各行业集聚态势呈现明显的差异,而且并非所有产业集聚效率与集聚程度成正相关,有些地区的部分行业还没有形成明显的集聚态势;而有些城区的部分行业则具有较高的集聚程度和集聚效率,处于集聚适度性范围之内,较合理;同时有些城区的部分行业过度集聚和效率损失现象也相当显著。
[Abstract]:Taking various industries of producer services in Chengliu District of Beijing as an example, this paper evaluates the suitability of spatial agglomeration of producer services. Firstly, it measures the scale of agglomeration by using the index of location entropy. On this basis, we use the catastrophe series method to study the agglomeration efficiency. Through the comparison between the agglomeration scale and the agglomeration efficiency, we can judge whether the producer service industries in the six districts of the city are in the appropriate range of agglomeration. Then it tests whether there is no significant agglomeration effect in the producer service industry in the six districts of the city, or whether the agglomeration is moderate or even excessive. The results show that the agglomeration situation of producer service industry is obviously different, and not all industrial agglomeration efficiency is positively correlated with the degree of agglomeration, which is represented by the six districts of Beijing. In some areas, some industries have not formed a clear agglomeration situation; Some industries in some urban areas have a high degree of agglomeration and agglomeration efficiency, which is within the range of clustering moderation, which is more reasonable; at the same time, some industries in some urban areas are overclustered and efficiency loss is also quite significant.
