Recently, Professor Wang Xiaowen's team from the school of economics of Lanzhou University published the SSCI Economic Journal "economic research ekonomska Istra" in zone 2 of JCR. The original article "modern service industry aggregation and its influencing factors: spatial interaction in Chinese cities" was published on ivanja. Professor Wang Xiaowen was the first author, Dr. Zhang Yunsheng was the second author, and Associate Professor Chen Nanxu was the corresponding author.

This paper makes an in-depth study on the development trend and influencing factors of modern service industry agglomeration in urban agglomeration by using spatial econometric model. It is found that the agglomeration degree of modern service industry in urban agglomeration is generally low, and the spatial distribution is relatively scattered. The leasing and business service industry has the highest agglomeration degree, and the education industry has the lowest agglomeration degree; The agglomeration degree of modern service industry has spatial autocorrelation, and has a significant spatial positive correlation with urban economic development level, innovation ability and urban scale, but has a significant spatial negative correlation with urban informatization and transportation infrastructure construction. This spatial negative correlation is inconsistent with the existing research. The research shows that when the urban agglomeration develops to a certain stage, the improvement of urban informatization and the improvement of transportation infrastructure construction will promote the modern service industry in the urban agglomeration to show a new phenomenon of "virtual agglomeration" on the network and gradually dispersed geographically, which is the reason why the city is improving the degree of informatization, New paradoxes may be faced when improving the construction of transportation infrastructure and promoting the spatial agglomeration of modern service industry. From the perspective of spatial interaction, this paper puts forward corresponding policy suggestions for promoting the agglomeration of modern service industry and realizing regional coordinated development.
