Self‐help in housing and chengzhongcun in China's urbanization

This article focuses on the housing issues of rural migrants arising from urbanization, with particular reference to chengzhongcun, a topic with considerable impact on policymaking. An attempt is made to understand the underlying rationale of self‐help in housing and the important role of chengzhongcun in sheltering rural migrants in the context of China's rural‐urban dichotomy. As demonstrated in this study, chengzhongcun accommodate, with little in the way of government resources and assistance, millions of rural migrants because of their social accessibility and affordability. While not denying their social problems, we argue that chengzhongcun in fact act as an innovative and positive agent to promote urbanization in present day China by housing massive numbers of rural migrants and assimilating them into cities. Current government policies towards chengzhongcun have generated a wide range of interest conflicts and confrontations. The consequences of such conflicts show that the government policies were problematic and unworkable, as they violated basic market principles as well as citizen rights. Policy strategy towards the redevelopment of chengzhongcun must acknowledge their credibility in the Chinese road to urbanization and requires more thoughtful and prudent consideration of migrants' demands for affordable housing.     

Regional economic performance in China1

This paper investigates convergence patterns among China's provinces using GDP data for the period 1952–97. We analyze convergence behaviour on the basis of Markov chains proposed by Quah (1993 ) and the generalized entropy decomposition proposed by Shorrocks (1980, 1984 ). Both sets of results show similar evidence of convergence within the pre‐defined geo‐economic sub‐regions, but no evidence is found of convergence between the sub‐regions. This finding has important policy implications for regional economic development in China. JEL classification: C33, E20, O47.

区港合一与厦门港城经济发展

区港合一指的是保税区、港口码头作业区实行一体化运作,在货物监管上采取一线放开、二线管住、区内宽松的自由贸易模式。按照构想,在厦门实行区、港合一,主要是充分利用象屿保税区坐落在东渡港区、区内无居民而便于实行隔离监管的优势,将象屿保税区与东渡港区进行组合,形成一体     

新时期广东省山区人口控制探析

20世纪90年代以来，广东省的山区人口增长速度虽然得到了控制，但与珠江三角洲相比还存在一定差距，地区之间发展也不平衡，生育水平仍不稳定，有效的人口控制机制尚末真正形成。因此，必须建立保障体系 和切合实际人口控制工作新机制，把人口控制工作寓于服务之中；加强计划生育队伍建设，提高队伍整体素质和工作效率。     

当前邮政储蓄机构违规经营原因与治理

近几年来,我国邮政储蓄业务迅速发展,已成为我国金融业中的一支不可忽视力量.邮政储蓄业务在高速发展的同时,也存在高息揽储、汇转储、公款私存、乱拉存款、乱设机构等违规行为,必须改革邮政储蓄机构管理体制、取消利率优惠政策、加强内部管理和强化金融监管,保证邮政储蓄机构健康发展,维护金融秩序稳定.
