同步与错位：规模视角下关中平原城市群城市与旅游协同发展研究

当前旅游城市化日益显著，从规模视角评价城市与旅游的协同发展具有重要意义。通过构建城市规模与旅游规模指数，对关中平原城市群2004—2017年的城市规模与旅游规模相关性进行验证，并运用位序规模法则、城市金字塔理论及空间错位指数探究城市规模和旅游规模在区域和城市尺度下的协同发展规律。研究发现：（1）区域尺度下城市规模与旅游规模均属首位分布，发展趋势存在错位；（2）各城市的城市规模与旅游规模在等级和空间上基本同步，少数城市出现错位，近年来空间错位程度有增强趋势；（3）低错位区城市，规模等级较低，中、高错位区城市，规模等级偏高；（4）城市规模与旅游规模的作用与反作用互动关系是其同步与错位状态形成的主要原因。

Synchrony and asynchrony: Study on collaborative development of city and tourism in Guanzhong Plain urban agglomeration from the perspective of scale

Tourism urbanization is becoming increasingly prominent. It is of great significance to evaluate the collaborative development of city and tourism from the scale perspective. Through constructing the city and tourism scale index, this paper verifies the correlation between city and tourism scale of Guanzhong Plain urban agglomeration from 2004 to 2017, and explores the collaborative development of the two scales from region and city perspective by using rank-size rule, urban pyramid theory and spatial mismatch index. The results show that: (1) The city and tourism scale distribution in Guanzhong Plain urban agglomeration are in the first station, but the development trend is different: the city scale distribution continues to be concentrated, and the tourism scale distribution tends to be balanced. (2) The city scale and tourism scale of each city are basically synchronous in rank and space, which a few cities appear asynchronous phenomenon. The degree of spatial asynchrony tends to increase in recent years. (3) Cities in low mismatch area have lower scale rank, while cities in medium mismatch area and high mismatch area have higher scale rank. (4) The interaction between city scale and tourism scale is the main reason for the synchronous and asynchronous phenomenon.
