20世纪90年代以来中国经济的动态效率

本文借助于西方宏观经济学中的索洛经济增长模型和拉姆齐 卡斯 库普曼斯模型 ,讨论了宏观经济中最优消费和储蓄的确定机制 ,并得出判断宏观经济运行动态效率的黄金定律以及修正黄金定律标准。同时 ,借助代际交叠模型从理论上探讨了自由竞争经济出现动态无效的可能性。在此基础上 ,我们利用黄金定律规则对中国实际经济运行的动态效率进行了考察 ,认为 2 0世纪 90年代初起中国经济运行处于一种动态无效状态 ,进而我们深入分析了造成中国经济出现动态无效的原因。根据中国经济处于动态无效的事实 ,并结合原因探索 ,我们最后提出了摆脱动态无效困境的若干政策建议。

Dynamic Inefficiency in China's Economy Since 1990s

The thesis discusses the optimum consumption and the decision mechanism of saving with reference to Solow's economic growth model and Ramsey-Cass-Koopmans model, deriving the golden rule of judging the dynamic efficiency of macro-economic operation and modifying the standards of golden rule. The possibility of dynamic inefficiency in a free competitive economy is also explored according to the overlapping generations model. On the basis, we have investigated the dynamic efficiency of Chinese economy with the golden rule, drawing the conclusion that the economic operation in China since 1990's has been in a state of dynamic inefficiency. Afterwards, we have analyzed the causes of dynamic inefficiency in Chinese economy. In the end, we have put forward some policy suggestions on escaping from the dilemma of dynamic inefficiency based on the facts and reasons of dynamic inefficiency.
