Urban, Suburban, and Exurban Sprawl in the Rocky Mountain West: Evidence from Regional Adjustment Models*
通过区域调整模型研究美国落基山脉西部的城市蔓延，发现人口与就业增长相互决定，并指出保护生活质量对区域长期繁荣至关重要。
Abstract. This article adapts a regional adjustment model to examine land use change in the Rocky Mountain West region of the United States. Three interrelated questions motivate the research. How does the proliferation of urban, suburban, and exurban sprawl in the Rocky Mountain West relate to the population and employment growth process? Are population and employment endogenously determined there? And what does this imply for the sustainability of economic development in the region? Through a series of regional adjustment models, the empirical analysis links population and employment growth in the Rocky Mountain West to explicit spatial outcomes and delivers substantive evidence of endogeneity between the two. The results suggest that the long-term prosperity of the region depends on the preservation of the high quality of life it offers, and that greater intergovernmental coordination, careful infrastructure planning, and attention to the character of its economic structure may help to accomplish this. Future research should focus on looking deeper into certain explanatory variables used in this analysis and on developing a better picture of what the spatial equilibrium that regional adjustment models emulate may look like.
