Study The Mechanism Of Agricultural Investment

Our country is a traditional agricultural country, agriculture is the foundation of the national economy, in shandong province as a big province of our country’s agricultural investment in agriculture to promote agricultural economic growth is particularly important. In recent years, with the speeding up of industrialization in our country, a large number of capital flows to the industrial field, and agricultural development relative lag, therefore, must further increase investment in agriculture, and improve the mechanism of agriculture long-term investment, improve the efficiency of the agricultural investment, to ensure the healthy, stable and sustainable development agriculture, lay solid foundation for the economic and social development.First of all, in this paper, the relevant literature review at home and abroad, a large number of literature agree that macroeconomic factors in the expenditure for supporting agriculture, agriculture, agricultural science and technology, the three basic construction expenditure on agriculture has important influence on economic growth, think the planting area of macro factors, agricultural labor, total power of agricultural machinery, fertilizers, agricultural investment in fixed assets is has an important effect on agricultural economic growth. But there is little literature involves how to improve the agricultural investment mechanism. No sound agricultural investment mechanism, cannot allocate agricultural aspects of investment, therefore, the research on the mechanism of agricultural investment of agricultural economic development is very important.Secondly, this article has carried on the brief review about the present situation of agricultural investment in shandong province, according to different characteristics of different stage of agricultural development in the narrative, emphasize the influence elements of the agricultural economic growth from several aspects, as well as some problems of the agricultural investment. The selection of variables in this paper and model theory basis.On the basis of literature review and theoretical analysis, using the unit root test, cointegration test and granger causality test analysis of investment in agriculture and agricultural economic growth in shandong province, the relationship among study, first, the fiscal expenditure for supporting agriculture in shandong province, the agricultural capital construction expenditure and agricultural science and technology three charges to the increase of agricultural output has obvious role in shandong province. Among them, the fiscal expenditure for supporting agriculture’s contribution to the agricultural output in shandong province, the largest agricultural science and technology three cost contribution to agricultural output after the expenditure for supporting agriculture, agricultural infrastructure spending on the contribution of agricultural output is minimal. Second, fiscal expenditures for supporting agriculture in shandong province, and agricultural science and technology three agricultural capital construction expenditure is the granger cause of shandong province’s agricultural output increase, and the increase of agricultural output in shandong province is not caused in shandong province fiscal expenditure for supporting agriculture, agricultural infrastructure spending and the cost of agricultural science and technology three granger reason.Also, this paper uses c-d production function model, has carried on the empirical research of shandong agricultural investment performance. Research shows that first, crop planting area of contribution to the agricultural output is larger, the agricultural labor appropriate amount and agricultural fertilizer, agricultural machinery total power, fixed asset investment has a great influence on the agricultural output also; Second, the output elasticity of agricultural investment in shandong province is greater than1, show that shandong province agricultural investment in the stage of increasing returns, and the output elasticity of labor value is greater than the output elasticity of capital; Third, crop planting area, the added value of agricultural labor and agricultural machinery marginal showed a trend of increase, chemical fertilizer, the added value of the marginal loss showed a trend of growth, agricultural added value of fixed assets of marginal showed a trend of decline, and crop planting area, agricultural labor, agricultural machinery, fertilizer and agricultural added value of fixed assets of marginal growth is not stable, volatile. Originally from the macroscopic and microscopic factors reflect the relationship with the agricultural production value.Finally, this paper from two aspects of micro and macro impact on agricultural production value are summarized, and puts forward some countermeasures for constructing the long-term mechanism in shandong province agriculture investment advice.
