Information Availability and Market Power in Export Competition: The Case of Regional Health Care Markets
分析了出口竞争的空间经济决定因素，发现信息可得性和市场力量显著影响西雅图医院向太平洋西北地区出口医疗保险服务，距离则产生强烈的负向效应。
In this paper I analyze the spatial‐economic determinants of export competition. I develop a competing central place spatial interaction model to analyze the spatial availability of information, market power, distance, demand threshold, and interregional market variables. Model estimates are based on national data from The Dartmouth Atlas of Health Care, and I examine Medicare health exports from the Seattle hospital market to markets throughout the Pacific Northwest. Information availability and market power for the Seattle export hospitals have a significant effect on export sales of hospital Medicare services. Intra and interregional competition with other major hospital markets are significant determinants of export competition. Distance to the Seattle market has a strong, negative effect on export sales and on patient migration from other markets.
