政府监管视角下跨境平台企业数据中心本土化与离境化选择的信号博弈模型研究OACHSSCD

The localization or offshoring of data centers by cross-border platform firms affects both their global operations and data security governance.It is very important to explore the interactive relationship between data center location strategies and gove-rnment regulation in the scenario of asymmetric information,which helps to improve regulatory effectiveness,and guide cross-bor-der platform firms'compliance decisions.Based on this question,we develop the signaling game model to make analysis of the mechanism,that is how firms make choices between data center localization and offshoring,as well as how government make re-sponse.We further take TikTok case to explore the sensitivity of critical parameters and changing in different equilibrium outcomes.The research results show that increasing government penalties can improve data security level in some extent;however,under the scenario of high data risk,excessively severe penalties may be detrimental for the government's ability to find data security risks.What's more,data security risk and per-unit data revenue have a nonlinear relationship.Although higher revenue expands the range of separating equilibrium,it cannot get rid of pooling equilibrium,even in some cases,pooling equilibrium has dominant ad-vantages.Moreover,a higher tax rate can shrink the region of separating equilibrium,meaning that strengthening tax-based regula-tion is insufficient to distinguish the compliance types of cross-border platform firms.These findings indicate that improving the le-vel of cross-border data governance need to make balances between data security and operations efficiency.Government need to es-tablish a differentiated and flexible regulatory system,while cross-border platform firms should enhance its identifiability and resilie-nce through lots of compliance investment and high quality level about information disclosure.
