First point is about the problems that private enterprises meet in self - development, including structural conflict of their products, non - standard management, lack of talent and experience in the field of foreign trade, low technical content in products, and hardness to get needed information etc. many private enterprises adopt the behavior of pursuing benefit of short period as export with low price, serve with shoddy tort and so on, all those may disturb the export market and lash the normal trading order. the last one is the restriction factor of external operation environment. as the entrance threshold of foreign trade field is high, resonance like professional association does not play a deserved role, the export encouragement policy of government is unsuitable, the land resource has become increasingly intense, and problems still exist in formulating and implementing of p artial laws and regulations
