Abstract

Since the reform and opening up, China's second and third industries continue to develop, the status
of agriculture is also constantly developing and changing, rural breeding industry from traditional breeding to
large-scale breeding across, breeding industry pattern has changed in different degrees. In this process, the
population flow is also increasingly active, the active population flow to the inflow and outflow of social and
economic impact. Reasonable breeding pattern is conducive to solving environmental problems, improving
productivity, optimizing industrial structure and promoting regional development. Therefore, it is of great
practical and theoretical significance to analyze the population flow, spatial pattern and driving mechanism of
rural aquaculture. Based on the data of the sixth national population census of the case study site, this paper
adopts qualitative analysis and quantitative analysis to establish a regression model of migration rate, migration
rate, net migration rate and total migration rate. Through the comparative analysis of the model, this paper
explores the changes of breeding industry on population flow and its driving mechanism. The empirical model
evaluation results show that the coefficient of determination is 0.7583, the adjusted coefficient of determination
is 0.7279, DW statistics=2.27, in addition to the grain output and consumption psychology factors, other
indicators were tested at the significance level of 10%, the model fitting degree is good. The results show that
per capita net income, urbanization rate and average elevation are the main influencing factors of migration
direction and intensity. From the perspective of the spatial agglomeration and evolution mechanism of rural
aquaculture, the regional resource endowment determines its basic spatial pattern, while the consumption
upgrading policy and market interest drive the change of the development pattern of rural aquaculture.
