Abstract:Based on the phenomenon that fishing scale is narrowing and income of fishermen household is declining in upstream of Beijiang river,this paper,from the perspective of element investment,experience-dependence and resource conditions,theoretically analyzes and empirically tests the fishing input-output of fishermen household in this area.The result shows that capital and labor input have positive simulative effect on quantity of fishing and value of fishing; experience-dependent phenomenon exists in upstream of Beijiang river and the resource conditions will only affect number of fishing through capital input and have not any impact on value of fishing.Therefore,this paper concludes that in order to increase fishermen’s income,it is essential to maintain and ppropriately increase hours of labour and not to blindly increase capital input.Technological innovation can be achieved through training and education and fishing places can not be changed randomly.
