[Purpose/significance] Data disclosure and openness can release value and promote academic exchange and progress, but few articles discuss the effect of data disclosure and openness on journal influence and specific mechanism. Therefore, this paper studies the relationship between data disclosure and journal influence in social sciences journals with certain practical and theoretical significance. [Method/process] Using the Synthetic Control Method, taking journal A as an example, the paper analyzes the changes of citation indexes before and after the data disclosure, and discusses the mechanism of journal data disclosure on the influence of journals. [Result/conclusion] Publication of social science journal data can significantly increase the impact of journals by increasing the Web's annual download rate and total citation frequency.
