摘要：地方性知识是民族旅游村寨形成差异化吸引力、维系地方文化传承和推动旅游可持续发展的重要资源，但其能否以及如何转化为游客价值共创行为，仍缺乏系统的理论解释与实证检验。本文基于自我扩展理论，从人地关系视角构建地方性知识影响游客价值共创行为的理论模型，重点考察地方依恋的中介作用以及自我监控的调节作用。本文选取贵州西江千户苗寨作为案例地，通过3轮实地调查获得460份有效游客问卷，并采用验证性因子分析、Bootstrap检验和SPSS-PROCESS模型，依次检验地方性知识的直接效应、地方依恋的中介效应以及自我监控的调节效应和有调节的中介效应。研究发现，地方性知识显著促进游客价值共创行为。游客对民族村寨认知体系、信仰体系和实践体系了解得越深入，越能够准确理解地方文化与生活方式，降低参与主客互动和文化体验的认知成本，进而更愿意实施旅游参与、信息分享、口碑推荐和目的地维护等价值共创行为。机制检验表明，地方依恋在地方性知识与游客价值共创行为之间发挥中介作用。地方性知识不仅拓展了游客对目的地文化特质和地方价值的认知，而且能够将外部文化资源纳入游客的自我概念，增强其地方认同与地方依赖，并进一步将认知扩展和情感联结转化为积极的价值共创行为。边界条件检验表明，自我监控显著强化地方性知识对地方依恋及游客价值共创行为的影响，并增强地方依恋的中介效应。相较于低自我监控游客，高自我监控游客对地方文化线索和主客互动情境更为敏感，更善于识别、吸收和运用地方性知识，因而更容易形成地方依恋并参与价值共创。本文不仅从游客微观行为视角拓展了地方性知识研究，而且揭示了“知识认知—情感依恋—行为共创”的作用链条，丰富了自我扩展理论在民族旅游情境中的应用。因此，民族旅游村寨应系统挖掘和活化地方性知识，将地方认知、传统信仰和生产生活实践融入旅游产品与服务，通过文化讲解、沉浸式体验和主客互动增强游客的地方依恋；同时，应根据游客特征实施差异化的知识传播与参与引导，在避免文化符号化、过度商业化和产品同质化的基础上，实现地方性知识的保护传承、游客价值共创与民族村寨可持续发展的协同。

Abstract: The rich and unique local knowledge of ethnic tourism villages is the key to the development of sustainable tourism. Previous studies have examined tourists' positive behaviors by using knowledge as a moderating variable, which weakens the efficacy of local knowledge in the context of ethnic tourism, and it is not clear how local knowledge affects tourist value co-creation behavior. Based on the self-expansion theory, the article constructs an effect model of local knowledge on tourist value co-creation behavior from the perspective of human-land relationship. Taking Xijiang's Qianhu Miao Village as a research case, data was collected to empirically test the relationship between local knowledge, local attachment and tourist value co-creation behavior. The results of the study show that in ethnic tourism context, local knowledge can positively influence tourist value co-creation behavior, and local attachment has a mediating effect between local knowledge and tourist value co-creation behavior, tourist self-monitoring not only positively moderates the intensity of the effect of local knowledge on local attachment, but also actively affects the indirect effect of local attachment on the relationship between local knowledge and tourist value co-creation behavior. This study not only provides a theoretical basis for more effectively protecting and inheriting local knowledge in ethnic tourism villages, but also offers beneficial references for destination marketers and management organizations to optimize tourism products and services.
