The successful ...As practical teaching receives higher value in the cultivation of college talents, the cooperation between higher vocational colleges and enterprises becomes a necessity to practice practical teaching. The successful cooperation bases on its management and operation. Establishing and perfecting the relevant laws and regulations and the inspection appraisal system can ensure the cooperation go smoothly. The government should coordinate the relationship among the government functional departments, colleges and enterprises, clarify the dominant and main body status of college-enterprise cooperation, improve the initiative and enthusiasm of all parties, as to ensure the coordinated development of college-enterprise cooperation. The old system,mechanism and conventions should be broken to promote talents＇ cooperation. The building of ＂double type＂ teachers should be intensified to finally achieve the great goal that cultivating the qualified builders and successors for the socialist country.展开更多
