Abstract: The production and living conditions of fishermen and their income growth are affected by various factors such as policy environment, aquatic product prices and natural disasters. Based on the fishermen''s household survey data and the national fishermen''s household income and expenditure survey data, the changes in the income and expenditure of fishermen''s households in 2017 and the factors affecting the income of fishermen are systematically analyzed. The results show that: (1)The fishermen''s family operating income is the biggest driving force for the growth of fishermen''s income, but the source of income is still relatively simple, and the structure of income has not changed fundamentally. It is urgent to expand the channels for fishermen to increase their income; (2) the labor costs has been increasing, and it has gradually become a key factor affecting the welfare of fishermen''s families. (3) There is a large gap in the income of fishermen in different regions, and the gap has further expanded. Based on this, it is proposed to build a long-term mechanism for the continuous increase of fishermen''s income, improve the internal income of the fishery industry, and improve the fishermen''s own income-increasing capacity in order to improve the production and life of fishermen and promote the increase of fishermen''s income.
