经济发展与区域信息鸿沟

效率优先，兼顾公平，几乎成为20世纪70年代后期以来我国制定国家经济发展战略，尤其是区域发展战略的基本定律。应当说，中国的发展是“成功”的：改革开放以来，我国经济实现了持续高速增长，创造了20世纪世界经济的奇迹：GDP由1980年的4514亿元上升为2004年的近136500亿元，年均增长达9％以上，国家综合国力迈入国际六强行列；国际贸易额由1980年的380亿美元增加到2004年11547亿美元，进入全球前三；外汇储备，1980年仅29亿美元，2004年底达6099亿美元，坐二望一。

Energy Price Shocks and Business Cycles in a Small Open Economy

This paper modifies a typical real business cycle(RBC)model with indivisible labor by explicitly including energy as a productive input and modeling the relative price of energy as an exogenous random process. In closed models, the production technology of firms is described by alternative specifications, which include Cobb-Douglas, regular CES and nested CES functions, respectively. Ours imulation results show that, no matter what production function is,energy consumption and employment are pro-cycle, and oil prices are counter-cycle.
