The Research On Macroeconomic Allocation Efficiency Of Green Public Investment In Hunan Province

Ecological environment is the basic space of human survival and development, thequality of regional ecological environment is directly related to the local population’shealth status, regional economic and social sustainable development. With the rapidgrowth of high-speed development of the socioeconomic and demographic, economicgrowth and population growth pressures brought to the ecological environment is alsogrowing. Scarcity of resources, Sharp drop in species diversity, Eco-environmentaldegradation, such as a growing number of environmental problems continue to appear,hampered sustained regional economic development gradually, even threat thenational security and social stability. Therefore, increasing environmental problemscaused great concern of the whole society. In this social context, it has a veryimportant practical significance on study of green public investment deeply.In this paper, Hunan green public investment for the study, in order to optimize thesize and structure of green public investment,for the purpose of increase the macroallocation efficiency of green public investment in Hunan, using normative andempirical analysis explore the green public investment in Hunan. First, on the basis ofdefining green public investment and allocation efficiency connotation, in-depthanalysis of current situation from the vertical and horizontal configuration of greenpublic investment in Hunan, and comparing Hunan with other provinces of the centralregion and individual provinces of east and west, the results showed that the scale ofgreen public investment in Hunan is insufficient, and the structure needs to beoptimized. On this basis, use the relevant mathematical models related to theforegoing analysis results to confirm the conclusion. The results show that the optimalsize of a green public investment in Hunan is10.23%,but the green public investmentin Hunan proportion of GDP is well below the optimal size. Green scale efficiency ofpublic investment in Hunan from the overall look is invalid； structural efficiencycoefficient is0.1921,compared with the developed areas at a low level, macroconfiguration efficiency there is a large room to improve. finally, based on the studyfindings and its factors, puts forward the following recommendations：attention toregional differences；develop green public investment planning with local conditions；improve policies and increase its enforcement；increase the level of marketization inthe green public investment； well-developed evaluation system for green public investment. This research expects these explorations can provide effective theoreticaland policy basis for the local government to improve the overall efficiency of publicinvestment and improve the ecological environment quality area.
