城市产业结构调整的可拓分析

An Extension Analysis on the Urban Industrial Structure

根据达州和国家的实际经济状况,产业结构比重均为"二三一",但两者之间的比重数据不是很协调。首先分析物元的影响因素:三次产业结构和七大产业部门,构造关联函数Ki(x)。接着运用可拓性质分析达州产业结构的优劣:第一、二产业结构系数的关联度均大于0,均高于全国,较理想;第三产业的关联度小于-1,为不相容问题,急需调整,其涉及部门具体表现在交通运输及仓储和邮政业、批发和零售业、其他三产部门。然后探讨不相容问题,即第三产业产值比重对整个物元产生很大的影响,使综合量值处于可拓域的较差位置。结合达州现状,确定了既要发展优势产业,又要着重发展第三产业的产业结构调整的变换策略。最后粗略估计达州产业结构调整的时间:第一产业比重调整须88年,第三产业比重调整须98年。因而达州产业结构比重要达到全国的理想水平至少需要几十年的调整,重点应放在第三产业。

According to the real economic situation of China and Dazhou, both of the proportions of industrial structure are ＂231＂, but the data of them is not very coordinated. Firstly, this paper analyzes the affecting factors on matter-elements： three industrial structures and seven industrial sectors, constructs dependent function. Then, by using extension properties, it ana- lyzes the advantage and disadvantage of industrial structure on Dazhou： the share of GDP of first and second industry is better; it of third industry needs adjustment, the related sectors specifically are in the transport, warehousing and postal services, wholesale and retail trade,other third industrial sectors. Afterwards, it explores the inconsistent problems, there is a huge im- pact on the whole matter-element for the output value of third industry which makes the comprehensive value to be worse in the extension field. With the present situation on Dazhou, it determines the transformation strategies on the industrial restructu- ring which are to develop both competitive industries and the third industry seriously. Finally, its adjustment time is simply solved： to adjust the proportion of first industry needs 88 years and to adjust the proportion of third industry needs 98 years. So its adjustment needs at least several decades to to achieve the optimal level of China, the emphasis should be placed on the third industry.
