Financial safety , especially bank safety , concerns the stability of a country and its economy . With the entry of foreign capital into China's banks , it is of great urgency to set up an early-warning system . By researching into six indexes , namely management and equity control , bank business control , bank equity stability , credit control , risk infection and financial supervision , we have constructed a warning index system for foreign-shared banks . The system may help financial supervision sectors with their decision-making in evaluating the effect of overseas financial institutions and setting up an efficient financial safety supervision system .
