Driven by the impulse for diversified operation and the good demonstration effect of Ping An Insurance，the insurance industry in the special economic zones of China should be expected to make innumerable cases on strategic entrance into the banking. However，so far，except Ping An，the insurance industry in the special economic zones of China gets involved in the banking only concerning financial investment with the aim of pursuing the price difference on the banking shares from the secondary market，while strategic acquisition of bank is rarely seen. This paper，using the empirical data based on which Ping An strategically entered into the banking，tries to make a positive analysis on the synergy of the acquisition of a bank by Ping An，and comes to the conclusions that the banking-insurance synergy of the acquisition of a bank by Ping An is significant and it successfully avoids following the track of overthrown Allianz，and in the future，the insurance industry in the special economic zones of China has stronger intentions and less rick to make strategic acquisition of bank than that of Ping An Insurance at that time. It can be expected that the confidence for the insurance industry in the special economic zones of China entering into the banking will be enhanced and the steps into the banking will be quickened.
