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.

我国入境旅游发展现状、趋势预测及策略分析

通过对1997—2006年我国旅游服务贸易出口国际市场占有率指数、旅游服务贸易竞争优势指数和显示性比较优势指数的比较，可以看出我国旅游服务贸易国际竞争力尚不强。结合1978—2007我国历年入境旅游人次和外汇收入数据，通过建立时间序列模型，可以对未来五年我国入境旅游发展趋势进行预测。建议根据我国入境旅游消费结构特征，采用从宏观上实行差异化引导等策略。

我国炼油工业应实行改造与新建并举的方针

目前我国炼油工业的生产能力，特别是加工中东含硫油的能力严重不足，为适应国民经济发展的需要，扩大炼油能力十分必要，根据测算，2010年我国炼油工业的加工量应达到3亿吨，2020年达到4．5亿吨，若按开工率90％计，则2010年我国炼油能力应达到3．3亿吨，2020年达到5亿吨，因此，从现在开始的10年内，需新增炼油能力1亿吨左右，在下一个10年，即2010至2020年，还需新增能力1．5亿吨，根据我国国情，因地制宜，充分利用现有装置潜力通过技术改造来发展炼油工业是十分必要的，但是大型，先进，一体化是我国炼油工业今后发展的主要方向，兴建新厂可采用先进的工艺技术和新的管理机制，取得较高的经济效益，因此，我国炼油工业的发展实行技术改造与兴建新厂并举的“两条腿走路”的方针。
