摘　　要：本文建立了一个由资源部门和一般产品部门构成的两部门Ramsey理论分析框架,在此基础上分析了资源部门的资本密集程度提高、生产难度加大、垄断定价(垄断高价或者低价)、对外依存度提高对我国经济增长和社会福利的影响。研究表明:(1)资源部门开采难度越大越不利于社会福利的改善和短期的经济增长;(2)资源部门的资本密集程度与社会福利状况为"U"型关系;(3)对资源部门的垄断定价会损害两部门之间最优的资本和劳动力配置状况,降低短期经济增长速度,造成社会福利损失,且垄断低价对经济造成的损失大于垄断高价;(4)如果国外始终具有根据国内资源部门的生产成本进行垄断定价的优势,资源部门对外依存度越高,则国内的社会福利损失越大。此外,上述这些因素均不影响经济的长期增长率。This paper develops a two- sector Ramsey model,which includes one energy resource sector and one general products sector. It analyzes the effects of the energy resources production difficulty,capital- intensive of natural resource sector,the monopoly pricing of the resource and the external dependence of resources,on china ＇s economic growth and social welfare. The increase of the energy resources production difficulty is not conducive to improving the welfare of the whole society and the short- term economic growth. It also found that there is U- shaped relation between capital- intensive of natural resource sector and the welfare of society. The monopoly pricing,including high and low monopoly pricing in resources sector,damages the balanced allocation of domestic capital and labor between sectors,which further harms the short-term economic growth and social welfare. The negative effects caused by monopoly low prices are greater than that caused by high prices. If resources price always keeps domestic production cost oriented pricing,the external dependence of resources would slow down the short- term economic growth and the long term social welfare. However,these factors do not affect the long- term economic growth.
