Comparative Study On Production Factor Allocation Of Citrus Between China And America

Chinese citrus industry has proceeded successively since market-oriented circulating system reformation of fruit started in 1984. Nowadays, Chinese annual yield of citrus is the second in the world and citrus industry is the fundamental industry to advance Chinese agricultural economy. However, Chinese citrus yield per mou remains low and is far below that of America in the recent 13 years. The second maximal annual yield depends on the maximal planting acreage completely. Besides, Chinese citrus growers have to face the question of decreasing revenues after China entered WTO. Thus, it is urgent to increase yield, decrease costs, enhance competitiveness of citrus industry and increase grower's net revenues. Nevertheless, few researches have analyzed the determinants of citrus yield per mou, especially quantitative analysis on changing of citrus growers' net revenues on the basis of changed input levels. That research has not been made yet in China.The overall goal of this research is to explore the various factors that have impacts on the citrus production and provide basis for optimizing Chinese citrus resource allocation by combining with the principle of optimal production factor allocation. In order to achieve this goal, this research will have the following specific methods:· Establishing the citrus production function model;· Exploring the determinants of citrus yield per mou, quantitatively analyzing influence of various factors on the yield and citrus growers' net revenues , and reckoning contribution ratio of technical progress;· Estimating optimum input levels of citrus production, comparing them to actual input levels, and analyzing the rationality of Chinese and American citrus resource allocation, so as to provide basis for optimizing Chinese production factor allocation of citrus.The system model uses dynamic C-D production function model raised by Tinbergen. The data of yield and input levels per mou from 1991 to 2003 will be used to estimate the above model. The methods of estimation are as below: estimating production elasticity by LS; estimating contribution ratio of technical progress by Solow residual method; estimating optimum input levels by the principle of optimal production factor allocation.The result of the research indicates that Chinese citrus productivity is low and input levels of citrus production change frequently; Chinese citrus industry has the advantage of costs, but still has some hidden troubles; determinants of Chinese citrus production are...
