基于产业结构视角的重庆市宏观投资效率研究

Study of Chongqing municipal macro-investment efficiency based on industrial structure perspective

大量的投资推动重庆经济高速增长,投资效率决定着重庆经济增长的可持续性。利用ICOR指标的分析表明,重庆直辖以来,投资效率不高且有恶化的趋势。从产业结构的角度来看,造成这一现象的原因主要是产业结构不协调,表现为:第一产业投资薄弱;第三产业投资效率低却占用了大量的投资;第二产业的投资效率虽高于第三产业,但还有很大的提升空间。优化投资产业结构、提高投资效率的对策是:加强第一产业基础建设投资;统筹协调第二产业投资,优化产业内部投资结构;发展生产性服务行业,提高房地产和公共事业投资效率。

A large amount of investment promotes rapid growth of the economy of Chongqing, and investment efficiency determines the constant speed of economic growth of Chongqing. The analysis of ICOR index indicated that, since Chongqing became the municipality directly under central government, investment efficiency is not high and has the trend of deterioration. On the viewpoint of industrial structure, the reason for this phenomenon is mainly that industrial structure is incongruous, and that the investment on the primary industry is weak, that investment on the tertiary industry efficiency is low but takes up a large amount of capital, that although the investment efficiency of the secondary industry is higher than the tertiary industry, there is very large promotion space. The countermeasure for optimizing investment structure and raising investment efficiency is to strengthen the basic construction investment of primary industry; to make overall plans and to coordinate the investment on the secondary industry, to optimize the structure of investment inside the industry, to develop the productive service industries, and to raise investment efficiency of the real estate and the government utility.
