Studies in the nonmetropolitan population change literature have largely focused on the role of natural amenities and economic restructuring, but few have focused on the role of public services. This paper addresses the question of whether public services in nonmetropolitan counties, specifically the outcomes of public schools, could attract migrants. We use a Poisson regression technique little-used in the migration literature to control for push and pull factors driving migration patterns and control for school quality. Results show that better schools can draw migrants to nonmetropolitan areas. Marginal effects are larger for nonmetropolitan counties not adjacent to metropolitan areas. 相似文献

ABSTRACTThe Danish food system has undergone a transition in the past 10–20 years, in which new quality conventions have evolved. Examples include increasing organic production and consumption, and increasing interest in local food, experience, community, taste and gastronomy. This article explores what influences if and how these new food trends are expressed in the food system. We conduct a comparative case study involving three product categories: craft beer, specialty flour and organic broilers. Craft beer and specialty flour have undergone a revolution, in which new flavours, products, practices and social relations are generated; by contrast, organic broilers have remained a relatively stable product category. The case studies demonstrate that the revolution is not just taking place in one domain, but it implies a multidimensional reconfiguration of the food system where an emphasis on multiple quality aspects and diversification of the product category is important. However, food trends are not the invention of the individual producer, but serve as common conventions that products can be related to, although their interpretation is not pre-given. In addition, a transition presupposes a shared vision and a coordination of activities among the actors in the food system or the mobilization of new actors who share this vision. 相似文献

Economic historians that study long-term changes during the nineteenth and twentieth century are fundamentally restricted by the availability of qualitative data. As a result, researchers are forced to either impute missing data, or otherwise combine datasets in some way. In this article, we demonstrate the versatility of state-space models in addressing these problems. Not only do they enable us to compose large data series of high quality, they also provide a clear estimate of how reliable this data is, allowing any subsequent analyses to take this reliability into account. We illustrate the advantages of a state-space model using the population of Belgian municipalities as a case study. By combining growth and level data, we are able to compute yearly population statistics of over 2600 municipalities from 1880 to 1970. 相似文献

中国人口文化素质指数及其空间分异 总被引:3,自引:0,他引:3
在构建人口文化素质指数的基础上,结合我国文化教育现状,对我国近十年的人口文化素质指数进行了定量与定性分析。结果表明:我国人口文化素质指数正在快速提高,但整体水平较低;人口文化素质指数的空间差异明显,东部最高,中部次之、西部最低,低于全国平均水平的省域主要位于西部;近2/3的省域发散趋异,收敛趋同的省域不到1/3,向上发散趋异的省域主要位于东、中部,向下发散趋异的省域主要位于西部,空间差异有扩大的趋势;人口文化素质指数与人口城市化水平、经济发展水平分别存在显著的线性关系和对数关系。 相似文献

本文在测算2004—2017年区域层面全要素生产率指数基础上,运用双重差分法全面考察了地方政府环境立法对于全要素生产率的影响。研究发现:中国整体全要素生产率面临严峻的下滑,尤其在2009—2014生产面全要素生年间更加明显,且东中西部区域间TFP指数分布情况在空间上呈“非线性”特征。地方环境立法对地方全要素生产率具有显著的促进作用,然而过度的环境规制措施却不能显著推动经济质量的提升、实现波特效应。 相似文献
