Evidence of a geography of knowledge sourcing is presented that rests on the technological similarity between the patents produced within a firm's R&D plants and those produced in the cities where those plants are located. We also find that the average complexity of patents generated by firms is positively related to the number of R&D units that they operate. That these benefits emerge for multi-locational firms operating within a single country suggests that the constraints on knowledge diffusion operate at a relatively disaggregate spatial scale. Finally, our results indicate that collaboration between headquarters and non-headquarters R&D units within firms has a differential impact on the complexity of knowledge produced and that state versus private ownership of firms influences the nature and impact of intra-firm collaboration.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"174 ","pages":"Article 103487"},"PeriodicalIF":4.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143154560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The trajectories of neighborhood change in local historic districts also varied across the neighborhood types, implying a greater possibility of gentrification and displacement in unstable lower-income neighborhoods.

We find that educational segregation is generally more pronounced than hukou segregation, and both are more severe at smaller geographic scales. Cities in eastern China and those with higher political status are the most segregated. Our results also support both spatial assimilation and global city theories. Socioeconomic inequality, cultural differences, and global connectedness are all positively associated with segregation levels, with these associations being strongest at the neighborhood scale, where intergroup exclusion is greater. In terms of the impact of the welfare regime, government divestment of public services and housing commodification exacerbate segregation. The provision of public housing helps mitigate micro-scale educational segregation. However, it exacerbates segregation between locals and migrants who do not qualify for housing subsidies. The emergence of polycentricity exacerbates micro-scale educational segregation. Some socioeconomic factors also contribute to segregation levels.

In addition, the impact of rebound effects of technological advancements on CO<sub>2</sub> emissions are also explored across cities. We find that an N-shaped relationship exists between GDP per capita and CO<sub>2</sub> emissions, supporting the EKC hypothesis in the PRD urban clusters. Urbanization significantly increases CO₂ emissions in cities with low to moderate emissions (e.g., a 1% increase in urbanization leads to a 0.963% rise in emissions in cities at the 25th quantile), while its impact diminishes in high-emission cities (e.g., resulting in a 0.199% reduction in cities at the 95th quantile).Additionally, openness and foreign trade exert a significant inhibitory effect on CO<sub>2</sub> emissions in all cities; and a rebound effect is identified in cities with medium and high emission levels (above the 50th percentile) in the PRD region. By analyzing the drivers of CO<sub>2</sub> emissions, taking into account development stages and rebound effects, this study highlights the heterogeneity in how different factors impact CO2 emissions across cities at varying stages of development within the PRD urban cluster.
