以行政归属划定城市景区遵循了管理边界，但违背了需求驱动下城市旅游流的运动规律。本文基于2007—2022年中国西部51个城市的面板数据集，应用空间面板模型识别西部城市旅游合作效应的圈层约束规律、效应机理及其异质性。结果表明：(1)研究期内西部城市旅游合作的空间传导效应微弱，行政区效应阻碍了城市旅游合作，现有合作主要借助交通邻近渠道开展；(2)西部城市景区的旅游空间效应总体在100～200 km圈层内显现，且以150 km为峰值呈双向距离衰减，在城市150 km旅游圈内提升景区数量、城市经济发展水平和交通客运量能促进城市嵌入西部旅游合作网络；(3)西部县级城市旅游发展具有景区敏感属性，景区效应以本地为主且具有圈层收敛特征，县域100 km圈层内的旅游合作更具价值；(4)西部地级城市在100～200 km圈层景区效应总体显著，在150 km圈层达到峰值，建议将200 km圈层内景区纳入地级城市旅游圈，并依托城市运营打造多样态的旅游兴趣点。本文实证检验了西部城市跨行政边界旅游合作的必要性，并给出西部县级市和地级市旅游合作的有效圈层。

The conventional practice of demarcating urban scenic spots based on administrative affiliation follows the management boundaries, but violates the movement law of urban tourism flow driven by demand.Based on the panel dataset of 51 cities in the Western China from 2007 to 2022,this study applies a spatial panel model to identify the circle constraint law, effect mechanism and heterogeneity of the tourism cooperation effect of the cities.It is found as follows.(1) During the study period, the spatial transmission effects of tourism cooperation among cities in the Western China were weak.The administrative division effect has impeded urban tourism cooperation, with existing cooperation primarily conducted through adjacent transportation channels.(2) The tourism spatial effects of scenic spots in cities of the Western China generally manifest within a range of 100～200 km, exhibiting bidirectional distance attenuation with a peak at 150 km.Increasing the number of scenic spots within a city′s 150 km tourism radius, along with enhancing urban economic development levels and passenger transportation volume, can facilitate the city′s integration into the western tourism cooperation network.(3) Tourism in county-level cities in the Western China exhibits scenic spot-sensitive attributes, with scenic spot effects being predominantly local and characterized by circle convergence.Tourism cooperation within the 100 km radius of counties demonstrates greater value.(4) For prefecture-level cities in the Western China, the effects of scenic spots are generally significant within the 100～200 km radius, peaking at the 150 km radius.It is recommended that scenic spots within the 200 km radius be incorporated into the prefecture-level city tourism circle, and that diverse tourism points of interest be developed through urban operations.The contribution of this paper lies in empirically verifying the necessity of cross-administrative boundary tourism cooperation in cities of the Western China and delineating effective spatial layers for tourism cooperation between county-level and prefecture-level cities in the Western China.
