| Investment is one of the main sources of the economic growth, the scale, structure and efficiency of it are not merely influencing the pace of the economic growth, but also the quality of the economic growth. Investment efficiency reflects the quality of investment and determines the continuity of economic growth. Since Chongqing is directly under the jurisdiction of the central government, a large amount of investment has promoted economy to increase continuously and fast, which plays an extremely important role in economic development of Chongqing. Investment efficiency determines the continuity of economic growth in Chongqing, more important to determine whether economy and social-developing goal could be realized smoothly. It has positive realistic significance to study the macroscopical investment efficiency in Chongqing for distributing resources rationally and giving play to the function of injecting capital into to the greatest extent for the purpose of guaranteeing the economic increase of Chongqing continuously, fast and healthily.This thesis makes a systematic and overall research to the macroscopical investment efficiency of Chongqing from two respects of total amount and structure, choosing the time and cross section sequence of the statistical annual for many years of Chongqing and China as the data resource, adopting several methods such as comparative analysis, measuring analyzing, etc. from the perspective of input-output and economical increase on the theoretical basis of macroeconomics, regional economics, industry's economics and the theory of investment.Analysis indicates that the current situation of the macroscopical investment efficiency of Chongqing trends to be low in general, which deteriorates more serious after being directly under the jurisdiction of central government, basically the way of economic increase still limited in inefficient extensive growth.. It is displayed in the following aspects. Incremental capital-output ratio relatively is large and inclined to augment after being directly under the jurisdiction of the central government. Capita-output-elasticity and elasticity of substitution of factor are too slight as well as the variation rate of total factor productivity. The industrial structure of investment is incongruous, the efficiency of the investment on the tertiary industry is low and the ratio between investments relatively too big. The coefficient of investment effect in the main economic zone fluctuates bigger and mean value is relatively low. The allocation efficiency of the capital among the regions is not high and presenting the downward trend in recent years. Author probing into the influence factor of the macroscopical investment efficiency in Chongqing, it is concluded that the scale of investment, investment structure, investment environment and technological progress have influenced investment efficiency together which is the reason lead to the present situation of investment efficiency, and every influence factor is expounded in detail. In the final chapter of this thesis the countermeasure and suggestion to improve investment efficiency is put forward pointedly, including optimize the industrial structure of investment and promote the upgrading of industrial structure; improve the validity that the product market and financial market dispose to the capital; the investment of reasonable overall arrangement, realize developing regionally in harmony; improve the scientific and technological level and realize the intensive economic growth; set up scientific public investment decision system and improve the efficiency of public investments.This is an innovative attempt to the comprehensive application of a regional efficiency analytical method of macroscopical investment. The innovative points of the thesis are that makes a systematic and overall research to Chongqing's investment efficiency at macroeconomic level from two respects of total amount and structure, and establish a analysis framework of a region's investment efficiency at macroeconomic level. But the thesis has not done bibliometric analysis to influencing factors and only chosen two respects of industrial structure and regional structure when researching the efficiency of structure of investment because of incomplete statistical data. |
