摘要
资源约束条件下的经济增长研究对中国经济的可持续发展具有重要的理论和现实意义。本文从宏观经济的微观基础分析入手,结合当前中国社会和经济发展的实际,在传统效用函数的基础上,引入了社会地位和资源两个影响因素,通过模型的静态及动态分析,重点研究资源约束对经济系统均衡条件、动态转移的影响。分析结果表明:①当期资源的使用量取决于资源的边际效用、消费的边际效用和时间贴现率的大小。②消费资本比足够大或消费足够多且资本与消费的边际替代率足够小是经济系统存在鞍点均衡的必要条件。③资源消耗足够多时,消费资本比将显著下降。并从资源约束这一角度解释了中国经济增长的投资消费失衡问题。最后从实证角度,利用协整理论验证了资源消耗与消费资本比之间的反向关系。
Studying on economic growth under the conditions of resource constraints is of great theoretical and practical signifieances to China＇ s economic sustainable development. In views of both the microscopic foundation of macroeconomy and China＇ s social and economic development, this article introduces two variables---social status and resource, based on traditional utility functions. It studies the equilibrium of the economic system and the corresponding dynamic transfers. The result from the model shows three main theoretical conclusions. Firstly, the quantity of the resources used depends on marginal utility of the resources, marginal utility of consumption and the discount rate of time. Secondly, higher c/k or more consumption, and smaller capital-to-labor marginal rate of substitution are necessary conditions that the saddle point equilibrium exists. Thirdly, if the resources are excessively used, c/k will decline significantly. At the same time, in view of resource constraints, the article also shows why there is the imbalance between investment and consumption in China. Finally, by co-integration testing, it is verified that resources consumption has a negative association with consumption-capital ratio.
