While prior studies emphasize the role of cognitive proximity, few have systematically distinguished between potential and realized knowledge flows in shaping regional specialization. This study introduces a dual-channel framework to examine how cities develop technological advantage through structurally available but unrealized opportunities (potential flows) versus actualized linkages (realized flows). Drawing on patent co-classification data from China's Industry 4.0 domains, we construct four indicators—<em>PBDI</em>, <em>PBRI</em>, <em>RBDI</em>, and <em>RBRI</em>—to trace intercity knowledge diffusion. Empirical results reveal that realized flows, especially direct linkages, play a consistently positive role in fostering specialization, while potential flows without integration mechanisms may hinder diversification. These effects are conditioned by local absorptive capacity and development level, with interaction analyses showing that technological relatedness amplifies the benefits of cross-domain recombination. The findings offer new insight into how local and external knowledge dynamics jointly shape industrial upgrading and provide policy implications for narrowing China's regional innovation gap.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"182 ","pages":"Article 103718"},"PeriodicalIF":4.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model integrated the artificial neural network with geographically weighted regression to account for nonlinear associations that are similar across proximate grids. By incorporating parcel-level land uses as variable weights, it also considered contextually varying associations across proximate grids located in different land-use parcels. Our CGWNN model achieved superior accuracy (R<sup>2</sup> = 0.85) compared to other models that ignored the aforementioned associations and widely used population datasets. The top three important variables were the distances to the nearest school, restaurant, and auto service, all negatively associated with population density. Additionally, the intensity of artificial light at night (ALAN) exhibited both positive and negative associations with population density in different regions, suggesting that the increased ALAN did not necessarily indicate higher population density in urban areas.

This study uses street view images and navigation data to investigate the spatial variability of waterlogging probability and dominant factors within a 15-min walkable radius of residential communities, applying interpretable machine learning. Focusing on Beijing's main urban area, the results reveal that within 150 m of waterlogging points, buildings have the greatest impact, followed by walls and roads, while sidewalks and plants play a minimal role. Streetscapes such as roads, walls, buildings, and sidewalks exhibit an inverted U-shaped trend in their impact on waterlogging risk, whereas sky and vegetation, particularly grass, significantly reduce the risk. Dominant factors vary spatially: in areas near airports and railways, dense buildings increase waterlogging risk, while walls and open sky mitigate it; in the eastern business district, walls and sky are the main contributors to waterlogging, but grass alleviates it; in decentralized areas, open skies reduce risk, while buildings exacerbate it; in the northern periphery, dispersed buildings and walls help reduce waterlogging; and along the Fifth Ring Road, walls, sky, and trees play a stronger role. Spatially, high-risk zones are concentrated along major roads, particularly between the 3rd and 4th Ring Roads in the south, forming a U-shaped pattern, while areas near the 2nd Ring Road show lower risk.
