it's a hard question , but i'm sure the reexamination of china's economic policies in the past may lead us to a right answer to the question . after the establishment of new china , our government employed numerous economics policies to stimulate the growth of china's economy . these policies , however , favored our domestic enterprises and protected them from international competition and these policies have contributed a lot to the rapid growth of both china economy and our domestic enterprises . after china's entry into to , chinese domestic enterprises will have to compete with their foreign counterparts . this new situation entails some changes of chinese economic policies . these changes will spur chinese enterprises to strengthen their competitiveness in the long run .
