The Impact Of Information Security Awareness On The Performance And Stock Price Of Listed Companies

In the context of big data,personal information data is increasingly important to the value of the business.With the extension of the personal information chain,data breaches have occurred frequently.The theory of interpersonal rumors suggests that when people are in a negative rumor environment,negative cognition will occur,and information transparency and control can suppress the generation of negative emotions and weaken their adverse effects.Studies have shown that when information breaches occur,consumers will have fabricated information,negative word-of-mouth and conversion behavior.On the one hand,the occurrence of these phenomena directly leads consumers to abandon the enterprise products,and on the other hand,it will affect the perception of the surrounding consumers,and ultimately lead to the deterioration of business operations.On the basis of systematically reviewing the factors affecting corporate performance,this paper applies interpersonal rumor theory to the business environment,and tests whether the two inhibitors of transparency and control proposed by interpersonal rumors can have a negative impact on firm performance when information breaches occur.To inhibition.Firstly,this paper selects two enterprises whose core business depends on the inventory user viscosity and incremental user growth.After the information leakage incident,compare their core business,financial indicators and DuPont analysis to test whether the different levels of inhibition factors can The negative effects ofinformation leakage play a depressing role.In order to further verify the above assumptions,this paper uses PSM-DID empirical analysis to analyze and analyze the enterprises related to information leakage incidents in the past decade.The empirical results show that the occurrence of information leakage incident will have a negative impact on corporate performance;at the same time,the transparency index has a positive impact on corporate performance,that is,it has a negative effect on the negative impact of information disclosure incidents;and the control rights index has a negative impact on corporate performance.This paper believes that providing users with higher control rights will affect the use and acquisition of user personal data,thus reducing the company's profitability and performance.
