Abstract: 【Objective/Meaning】The strategy of promoting rural revitalization should give full play to the role of financial lubricant and use financial means to promote the settlement of urban-rural income gap, which was of great significance to a certain extent to solve the problem of insufficient and unbalanced urban-rural development and relieve social contradictions in China. 【Methods/Procedures】Based on the VAR model, relevant data of Fujian Province from 1981 to 2017 were selected to analyze the role of the scale and efficiency of financial development in Fujian Province in narrowing the urban-rural income gap by using the Eviews software. Considering the leading role of Fujian's unique status of “One Belt One Road” core zone in foreign trade, the indicators of foreign trade were innovatively introduced to study the role of foreign trade in narrowing the urban-rural income gap. 【Results/Conclusions】The results showed that: The efficiency of financial development and the level of export trade were directly proportional to the urban-rural income gap, while the scale of financial development, the degree of financial bias and the level of import trade were negatively correlated with the urban-rural income gap, which played a positive role in curbing the expansion of the urban-rural income gap. Based on this, it was put forward that the income gap in Fujian Province should be narrowed by promoting the investment in supporting agriculture, developing new financial means to support agriculture, expanding the scale of financial development and adjusting the ratio of fiscal expenditure in urban and rural areas.
