Urban Influence on Costs of Production in the Corn Belt

This article determines the relative technical efficiency of rural- and urban-influenced crop/livestock enterprises in the Corn Belt. Farmers in urban-influenced locations are less technically efficient than farmers in rural locations. During 1998–2000, stochastic production frontier procedures indicate that a 10% increase in urban influence leads to a close to 4% decrease in technical efficiency. The most successful urban-influenced farms have controlled costs as effectively as rural farms. They have tended to de-emphasize that nondairy livestock activities—particularly beef and hogs—do not rely extensively on off-farm income, and have relatively large, less residential/lifestyle operations compared to less successful urban-influenced farmers. However, our statistical analysis clearly bears out the refrain in popular literature that urban proximity raises the cost for, and decreases the viability of, traditional farms.     

Rural Population Growth, 1950–1990: The Roles of Human Capital, Industry Structure, and Government Policy

Human capital raises rural incomes, but this effect is swamped by higher returns to human capital in urban markets. This leads to "brain drain" from rural areas. Populations grow more rapidly in rural counties that have a diversified employment base. Farm population grows faster (or declines more slowly) in counties with relatively high farm income, and nonfarm populations grow faster in counties with relatively high nonfarm income. However, higher farm incomes lead to slower nonfarm population growth and vice versa. Rural county government services financed by local taxes or debt have neutral or negative effects on population growth.     

Triple jump about urban land potential release in China

Recent two decades, the great changes take place in China, especially in land use area. After the marketization, the urban land potential of China releases gradually. Three models in this paper show the three stages of reforming land use system. This paper will give a clear picture of urban land use in China that spans nearly thirty years.     

论城市文化资源的资本转化

城市化资源系统是一个复杂集合体。其集聚性与分散性同时并存；多层次性与整体性同时并存；物态型与非物态型同时并存。我们必须坚持因地制宜、整体与重点相结合、资本转化利用与资源保护相结合、聚集与整合相统一、经济效益与社会效益并举的原则，通过项目开发转化模式、化资源的单体开发转化模式、化节庆开发转化模式、运营商开发转化模式等具体途径。实现其城市资源的资本转化和价值增值。     

现代城市管理若干理论述评

近年来国内外影响较大的现代城市管理理论有：生态城市管理理论、新城市主义管理理论、城市营销理论、经营城市理论、城市竞争力理论和数字城市理论等等。现代城市管理论的繁荣促进了城市管理科学向更深、更高层次的发展，但是仍然有许多不足。当代城市管理，尤其是我国的城市管理，理论研究有余而实证研究不足。未来城市管理的研究必将呈现进一步综合化、系统化的发展趋势。     

搞好中小城市绿化建设的几点思考

作者根据自身的实践 ,认为中小城市绿化建设应树立四种意识 :一是树立“规划见绿”理念 ,对城市绿化也要编制总体规划和详细规划 ,并构思布局一批特色绿化工程 ;二要强化“空间绿化”意识 ,以城市道路轴线 ,构建绿化网络 ,扩展绿色绿量 ;三要树立“精品绿化”意识 ,提高绿化质量 ,打造草坪、花坛、公园、街道等名牌 ,四要树立“市场经营”意识 ,建立起多元联动、全社会参与的城市绿化投融资新机制。

完善城市整体功能是旧城改造的方向

城市的更新、改造是社会发展的必然 ,如何通过现状调查、分析、研讨 ,找出城市建设的症结 ,使城市趋于完美是城市建设者的历史使命。但现实中 ,片面追求经济效益 ,发旧城改造之财 ,只能使城市变成“崭新的旧城” ,只有按城市发展的固有规律去完善城市的整体功能才是旧城改造的发展方向。
