本文在Solow模型框架下引入了资源中间品生产部门,在开放条件下分析了资源中间品贸易下贸易小国经济增长的基本路径,并考察了资源节约对资源中间品贸易和经济增长的影响。结果表明,资源中间品部门的资本存量和产量与资源中间品的国际价格呈正比,但与本国资本存量的总体规模无关。依据资源中间品的贸易模式,经济增长可以被划分为专业化分工、资源中间品出口和资源中间品进口三个阶段。通常经济增长会在第三阶段进入稳定状态,但当资源中间品国际价格足够低时,贸易小国可以突破资源禀赋存量的约束,实现可持续增长。资源节约可以提高可持续增长的资源中间品临界价格以及稳状资本存量,从而拓展经济增长空间。
In the framework of the Solow model, this paper introduces the intermediate production of resources, analyzes the basic path of economic growth under the trade of intermediate resources under open conditions, and examines the impact of resource conservation on the trade of intermediate products and economic growth. The results show that the capital stock and output of intermediate resources department are directly proportional to the international prices of intermediate products, but it has nothing to do with the overall size of domestic capital stock. According to the trade pattern of intermediate materials, economic growth can be divided into three stages: specialization of labor division, export of intermediate goods and import of intermediate goods. Normally, economic growth will enter a stable state in the third stage. However, when the international prices of intermediate products are low enough, small trade countries can break through the constraints of their natural resource endowments to achieve sustainable growth. Resource conservation can increase the sustainable growth of the critical value of intermediate resources and steady capital stock, thus expanding the space for economic growth.
