Land development impacts of mass transit have long been studied in the developed economies. Yet relatively little is known by the outside world about the Chinese experience due to China's rather short history in the development of modern mass transit and land/property market. This paper attempts to fill the gap by presenting evidence from China, with a detailed case study of Beijing. Selecting three newly built suburban transit lines in Beijing, the study examined land development context and estimated hedonic housing price models to measure the proximity premiums associated with these three lines. The empirical evidence in Beijing, one of the first tier mass transit cities in China, shows that investments in mass transit can have significant and positive impacts on land development. Properties with transit proximity enjoy sizable price or value premiums. The study also confirms the international experience: transit impacts on land development are unlikely to occur automatically; they rely greatly on supportive regional and site conditions. Integrated planning and design for mass transit and land development are critical to expand and maximize the return of transit investments. 相似文献

Despite an effort by Congress to design a market-based public policy to limit development on certain coastal barriers and protect the federal treasury from paying for recovery from expensive natural disasters, growth continued on these shifting sands. In enacting the Coastal Barrier Resources Act, federal policymakers may have overlooked the key role of state and local governments, as well as the role of local developers, landowners, and realtors in shaping development on coastal barriers. By itself, the act will not prevent development. In fact, it appears that development in areas designated under the act will occur if (1) development pressure is strong enough to overcome the disincentives posed by the act, and (2) state and local governments facilitate development. For example, a local government may substitute its own subsidies for those withdrawn by the federal government. Nothing in the act prevents this from occurring. This article examines the key forces affecting development in areas designated under the Coastal Barrier Resources Act (CBRA) and seeks to explain why development has occurred in some designated areas, despite the withdrawal of federal subsidies. Using case studies of selected coastal barriers designated by the act, as well as surveys of state coastal managers and key informants, the research shows that the Coastal Barrier Resources Act, by itself, will not prevent development from occurring in the designated coastal areas. 相似文献
