An Imbalance Analysis of China's Agricultural Machinery Distribution
利用1991-2010年中国30个省份的面板数据，通过洛伦兹曲线和基尼系数从总量、结构和效益三方面衡量农业机械装备水平的不平衡性，发现综合基尼系数呈波动下降趋势，并识别出经济发展水平、政策、自然条件等主要影响因素。
It was vitally significant for establishment of policies to agricultural mechanization to grasp law of regional differences of the agricultural machinery equipment level and find out the main influence factors. In this paper, it was used that panel data from 30 provinces(cities, districts) of China mainland during the 1991-2010, according to the Lorenz curve and the principle of Gini coefficient, it was comprehensively measured the imbalance of agricultural machinery equipment level from three aspects of total amount of agricultural machinery equipments, structure and benefits, the results were shown as follows: During 1991- 2010, comprehensive Gini coefficient of China agricultural machinery equipment level showed the trend of decline in fluctuation. The Gini coefficient of total agricultural equipment and agricultural benefits showed an invertedUtype; the Gini coefficient of large and medium- sized tractor- supporting agricultural machinery which reflected the equipment structure imbalance of agricultural machinery showed a trend ofUtype; the Gini coefficient of small tractors- supporting agricultural machinery showed a downward trend. They were the main factors of influence on regional disparity of agricultural machinery equipment level that economic development level, agricultural machinery development and promotion policy, natural and geographical conditions, planting system.Therefore, according to the different regional economic conditions, natural endowments, farming systems, it should take the appropriate technical route and policy measures to promote the coordinated development of agricultural mechanization in different regions. Not only should main research of grain production mechanization, but also should coordinate the development of efficient characteristic agricultural mechanization in non major grain producing areas,enhance the agricultural machinery's research and development efforts and popularize efforts in Southern China's rice planting area and in hilly region.
