Investment in agricultural research focused on identifying the economic model


And investments in research focus between different regions. 3.2 between the different agricultural research priorities for investment to determine the average benefits from an integrated point of view, the highest total benefits of rice research. Effectiveness of agricultural research than the other three combined, indicating that rice is the most important agricultural products in Jiangsu Province. The total efficiency of wheat after rice research,abercrombie and fitch canada, but in absolute terms, far less than the rice. Cotton research efficiency and Di in wheat. But higher than the rape. Benefits in total benefits of cotton producers accounted for 50%, indicating a greater role in cotton farmers' income. Therefore, if the total effective size of the selection according to research investment priorities should be in accordance rice, wheat, cotton. Rape of the order. '104 · Nanjing Agricultural University 17 However, this does not mean that the research funds fully committed to the total benefits to large products, and the total benefits of lower product not invest in scientific research. There is also a moderate problem, we must consider three factors affecting the party and, one is the product of the question, is irreplaceable. Since different products have different value, and therefore they can not completely replace each other, even less effective, it must be studied. In fact, in order to ensure that agricultural production be maintained at the same level, but also must maintain a certain degree of investment in equilibrium. The second is research the law of diminishing marginal returns. In the research output function, when agricultural research investment of a certain level, the phenomenon of diminishing returns is bound to occur. Because there is always a current level of research investment, and different agricultural research output function may be in different stages of development. If the increase in rice R & D investments increase the total benefits of resource efficiency as a large increase in cotton research, research resources should be put in more time to cotton on. In terms of total benefits as a benchmark of rice research. After calculation. L-fold increase in research funding of wheat, cotton increased 1.4-fold, 3-fold increase in rape in order to achieve the benefits of rice. The third is research investment sensitivity. First, changes in investment analysis and research on the costs of how much impact the success rate, and then calculate the total benefits of investment impact of changes in the sensitivity of the degree of sensitivity for large products, should give priority to increasing investment in scientific research, and vice versa to reduce investment. 3.3 in different agricultural areas of research and asked to identify priorities of agricultural research investment priority setting after. Need to identify key agricultural areas. The following analysis of rice, wheat research resources in the regional distribution. Rice research in four major agricultural products, the total benefit is the highest, which benefits both producers and consumers have the highest efficiency. This shows that the income of farmers or consumers, to meet demand for its food is the most important agricultural products. According to calculations show that research investment in the preparation of rice farming areas are not large differences in the benefits, so the investment in scientific research should be more balanced distribution. However, if the research goal is to make the maximum total benefits should increase investment in scientific research Xuhuai rural areas. The total effective area of ​​research because of 45.4056 million yuan, is the highest. In addition, from the actual situation analysis, to enhance production capacity of rice farming areas Xuhuai. Help ease the demand for rice farming areas in Taihu Lake,nike free run, the area of ​​labor into secondary and tertiary industries go, the higher social benefits. However, if the research objective is to spillover benefits FI largest agricultural areas should be in or Lixiahe Ningzhenyang agricultural areas for scientific research, this time in addition to the Taihu Lake, Xu difficult agricultural areas farmers may suffer small losses,abercrombie canada, caught the rest of the production of agricultural areas can be profitable. The total efficiency of wheat after rice research,burberry pas cher, but research institutes in different agricultural areas produce benefits vary greatly. Maximum efficiency of agricultural research Lixiahe area. Followed Xuhuai agricultural areas. This indicates that these two should focus on rural areas to increase investment. In short. Built using principles of economic surplus model. Determine priorities for investment in agricultural research method is a feasible, high degree of advanced scientific measurement methods, which effectively solve resource allocation decision-making and scientific research issues. Therefore, the results of this study raise the level of China's agricultural research and resource utilization,diesel jeans online, improve the efficiency of input and output of agricultural research, agricultural science and technology to enhance agricultural development in China's motivational, are of great significance.
