Rising costs typically reduce inflows while increasing outflows, particularly in large cities. Given the current housing affordability crisis in many countries, we extend evidence on the links between housing market dynamics and internal migration in three principal ways. First, we consider not only housing costs but also supply and distinguish between standalone and attached dwellings to provide more granular evidence. Second, we contribute a case study of Australia, where evidence is critically lacking despite remarkable housing price increases and wide regional price disparities. Third, we assess potential changes since COVID-19. To these ends, we estimate a Poisson pseudo-maximum likelihood regression with origin, destination, and year fixed effects on annual bilateral migration flows between capital cities and non-metropolitan regions from 2012 to 2023. We find that internal migrants respond to both origin and destination housing prices. Specifically, a 10 per cent increase in average prices at origin results in an 8.07 per cent increase in outflows, while a similar increase in destination prices reduces inflows by 3.96 per cent. Interregional flows also respond to an increase in housing supply at origin, albeit less so than an increase in housing price. The association between housing market dynamics and migration was greater at origin than destination before the pandemic. However, since COVID-19, migration flows have become more responsive to housing price at destination, particularly in the detached housing market. These results highlight the growing role of housing market dynamics in shaping internal migration flows.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"178 ","pages":"Article 103548"},"PeriodicalIF":4.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520938","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}

While amenity migration, namely migration dominated by amenity factors, has been widely identified in developed countries with numerous case studies, the question of the extent to which amenity shapes migration patterns in developing countries, especially concerning the spatiotemporal heterogeneity, is less well answered. To address this gap, the paper takes China as a case to examine spatiotemporally varying roles of amenities in affecting migration patterns. The results of panel model and cross-sectional regressions showed increasing effects of amenities with upgrading development stages, while the effects of economic opportunities are weakened, indicating an emerging trend of amenity migration. The results of the multiscale geographically weighted regression model further confirmed the varying effects of various amenities in different regions. The specific roles of amenities depend on the local context. In addition, migration patterns are influenced by different dominant factors in different places. While the impact of economic opportunities on migration is important in less economically developed regions, the impact of place-specific amenity is even more important in economically developed regions. Finally, migration transition arising from changes in migration dynamics and its spatially heterogeneous processes were discussed.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"178 ","pages":"Article 103577"},"PeriodicalIF":4.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520937","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}

A triangular framework was established to evaluate the spatial flow and disparities of virtual WEC across 30 provinces in China. Significant differences were identified between the production and consumption sectors, highlighting a strong connection between energy and carbon, as well as a trade-off with water. Approximately 63% of the provinces demonstrated a moderate degree of coordination within the virtual WEC system, which was found to negatively correlate with their levels of social and economic development. The transfer of virtual WEC was observed from the less developed western and northern regions to the economically advanced southeastern coastal areas, exacerbating disparities in resource distribution and carbon emissions. Therefore, a joint shared responsibility mechanism for carbon reduction is proposed, utilizing the water fairness coefficient to assess inequities in responsibility arising from the spatial flow of virtual WEC. Nationally, it is recommended to intensify efforts in coordinating WEC management and implement a carbon compensation strategy for regions with disproportionate burdens.

This study used urban scaling laws to investigate relationships between city size and carbon emissions from population and land perspective across 294 Chinese cities. Results showed a sub-linear relationship between urban population size (UPS) and carbon emissions and a super-linear relationship between urban land size (ULS) and carbon emissions. Regionally, cities in central regions demonstrated higher carbon emission performance than those in western and eastern regions. The land perspective indicated lower carbon emission performance compared to the population perspective. Both perspectives revealed non-linear relationships between city size and urban scaling exponent for carbon emissions, characterized by multiple minima.
