[Objective] This paper constructs a financial knowledge graph from the perspective of equity, which provides new directions for financial research. [Context] The existing financial research mainly analyses the data of creditor’s rights. Our study helps regulators and researchers through visualization of financial equity data.[Methods] With the help of knowledge connection, we constructed a knowledge graph for Chinese financial equities based on their ownership and the proportion of shareholdings. Then, we visualized the relationship among the financial institutions.[Results] Our knowledge graph had more than 45.86 million nodes and 145.74 million relationships. Users could query entities and their relationships for up to three layers.[Conclusions] The proposed method analyzes the financial network from the perspective of equity, which breaks through the limitations of existing research focusing on creditor’s rights.
