农业产业化地域模式初步研究——以江苏省为例

In this paper the areal model of agricultural integration is defined as the major model of agricultural integration adapted to the sort of leading products, marketing orientation, the degree of rural economic development and the organization level of farmer household in different regions. The formation mechanism of areal models of agricultural integration is as follows:1) sort of leading products is the fundamental factor; 2) marketing orientation is the key factor; 3) the degree of rural economic development is the restrictive factor ; 4) the organization level of farmer household is an important factor; and 5) location,resources and environment are the external conditions. There is great intraprovincial imbalance of social and economic development within Jiangsu Province,and the areal models of agricultural integration should be differentiated with concret conditions of each region.The processing factory driving model,special market radiation model and leading products based model are recommended as the major areal models of agricultural integration in Southern Jiangsu, and the intermediary organization servicing model and the plural participation model are recommended as the major areal model of agricultural integration in Northern Jiangsu. Some typical examples of areal model both in Southern and Northern Jiangsu are analysed in detail: 1) the dairy integration model in Nanjing city region;2)the model of Yangchenghu crab integration in Wuxian county;3)the pearl integration model of China's Weitang Pearl Market; 4)the model of garlic integration in Dafeng county; 5)the model of egg integration in Hai'an county;and 6)the model of laver integration of Yucheng Group Company.
