While there have been studies on the relationship between higher education institutions and regional economic growth, few have delved into the economic impact of decentralized higher education institutions at the county level and associated reginal disparities in terms of socio-economic development. Utilizing the data of the Chinese universities that started to establish their campuses in counties since the year 1999, this study investigates the influence of rural university campuses on county-level GDP and industrial composition spanning from 2001 to 2020. It also delves into the temporal dynamics and regional discrepancies associated with this impact. The findings of this study show that (a) rural university campuses wield a notable positive influence on the GDP of their respective counties, particularly shaping the structure and ratio of secondary and tertiary industries; (b) the magnitude of this effect is contingent upon the duration of campus establishment and growth, intensifying over time; (c) variations in this impact are evident across the eastern, central, and western regions of China, where there are vast socio-economic differences. This study underscores the significant spillover effect of higher education decentralization on county-level economies and advocates for the pivotal role of rural university campuses in propelling county-level economic progress. Additionally, it proposes coordinated policy support from national, regional, and rural university campus authorities; the establishment of requisite support structures; and the comprehensive consideration of regional nuances.

This study examined the relationship between the urban dialect ability and academic performance of migrant children, as well as the role of school integration between the two. This study collected data from 1687 migrant children aged 5–15 from 28 county-level units (counties, districts, cities) in China, sourced from the 2010 China Education Panel Survey (CEPS). The research results indicate the following: (1) the urban dialect ability of migrant children has a significant positive impact on their academic performance. (2) School identification, peer–peer engagement, and peer acceptance, as the three dimensions of school integration, play a mediating role between the urban dialect ability and academic performance of migrant children. Overall, this study provides theoretical support and policy recommendations for promoting school integration and academic performance development for migrant children.
