Abstract：Regional specialization gradually becomes an important production mode in modern agriculture, which has been realized from labor division and development in agricultural production. "One Village One Product" or "One County One Industy" is one of its spatial forms. According to previous studies, under certain conditions, specialized agricultural production areas can be formed by government's strong promotions. In other words, the government, especially the local government as a main economic agent in regional economic development, has a direct impact on the spatial diffusion environment of the agricultural professional projects, thus affects the speed and the scale of the formation of the agricultural specialization production areas. By taking Xixia county's mushroom industry as an example, which is gradually developed by the government's promotions, this paper used survey data of mushroom cultivation in Xixia and found that: (1) the spatial distribution of mushroom planting was scattered over among the early participation villages, and was clustering among the late participation villages; (2) the villages with similar initial intensity was spread over the county (3) the villages with larger or smaller production scales had formed significant spatial agglomeration, which was also found within the villages with similar degrees of specialization.In this study, AMOS 21.0 and the Structural Equation Model (SEM) were used to explore the influence of the government on the spatial diffusion of agricultural projects. Results showed that the government had a significant positive impact on the intensity and speed of the project spatial diffusion and the current production scale and specialization level (the influence coefficients are 0.438, 0.213, 0.459 and 0.815, respectively) . Non-governmental factors (e.g.geographical conditions, resources, economic background, etc.) changed the uniformity of the spatial spread of professional projects under the influence of the government. This caused the spatial distribution of low level equilibrium to be gradually replaced by the spatial distribution of high level agglomeration, and the reverse spatial diffusion characteristic of "area-to-point" appeared. This study provides a reference for the realization of specialized production in agricultural areas.
