以重庆库区为例 ,首先从静态和动态两个方面分析了三峡库区经济的二元化特征。静态特征表现在城乡之间资本存量、生产率和收入水平三个方面的差异。动态特征主要表现为投资结构变化中工业投资比重远远高于农业 ;比较劳动生产率演变中工业部门的比较劳动生产率远远高于农业部门 ;城乡收入水平和消费水平变动中非农业生产者的收入和消费水平远远高于农业生产者的收入和消费水平 ;产业演进过程中 ,产业内部的产业分工和技术等级上的二元性。其次 ,探讨形成三峡库区二元经济结构的成因。最后 ,提出改变库区二元经济结构的具体途径是加强库区中心城市与周围地区的经济联系 ,发挥中心城市对库区的带动作用 ,实现城市工业与乡村工业互动和工业化与城市化互动。

Taking Chongqing reservoir site as an example, this paper analyzes the characters of dual economic structure in the Three Gorges Reservoir Area firstly from static and dynamic state The static characters represent the dualities in capital accumulation, productivity and urban rural income standard The dynamic characters represent the proportion of industrial investment being much higher than that of agriculture, comparative productivity of industrial sector higher than that of agricultural sector, the income and consumption standard of urban producers higher than that of rural producers Additionally, in the Three Gorges Reservoir Area, besides the agro industrial or urban rural duality, there exists duality in the division of industrial sector and the grade of technology, which makes the duality in the Three Gorges Area go beyond the bound of agro industry or urban rural area given by the traditional dual economic theory, hence putting up a multi termed character Secondly, this paper discusses the four reasons which lead to the duality in the area, including: 1) accompanying capital economy before liberation made the duality come into being immediately; 2) after liberation, the adoption of Super Industrialization Model enhanced the dual constriction between urban and rural areas in the Three Gorges Area, making the duality expand swiftly and taking on an extra intensive state; 3) relatively close productive structure and the shift to an earlier time lead to the lower acceptance for surplus labor forces, this makes the dual economic structure appear an excessively stable state; and 4) the large span between inter industries or inside industries leads to the clear dual structure in the division and the grade of technology Finally, the paper gives the pipelines for changing the dual economic structure in the Three Gorges Area The method is to strengthen the economic relation between central urban areas and rural area around, exert the driving effect of central cites to reservoir areas, realize the industrialization in urban and rural areas at the same time Thus starting in light of economic relation and seeking the mutual compensative chain to establish the industrial contacts is a good and practical pipeline to reduce the dual discrepancy in the Three Gorges Area
