Practical education is an important part of talent training in urban and rural planning. In order to meet the needs of industry development, deepen educational reform and solve the dilemma of practical education, it is very necessary to study the mechanism of enterprise participating in planning education. After analyzed the main modes of participation of planning enterprises in China and conducted comparative studies at home and abroad, it is found that the paths and mechanisms of Chinese, British and American companies' participation in professional education are similar, but British and American are better in maturity and depth. And there are some deficiencies in enterprise enthusiasm, government driving force, discourse power of industry organizations, school curriculum system of China. To solve these problems, it is the key to proposing the strategies such as government incentive and guarantee, industry organization guidance, joint training of schools and enterprises, as well as the multi-agent collaborative talent training mechanism.
