“Close” and “Clean” are the core elements of the new type of governmentbusiness relationship which is the basic and key link to promote the modernization of the national governance system and governance capacity. Therefore, the measurement of the level ofthis new type of government-business relationship is of great significance. Taking 11 cities in Zhejiang province as a sample, we builda “close andclean index”of the new type ofgovernment-business relationship of Zhejiang province, including seven aspects of service, support, activity level of enterprise, closeness perception, government incorruptibility, government transparencyand corruption perception.Then, with the efficacy coefficient methodwe measure the level of government-business relationship of 11 cities in Zhejiang province in 2018. The evaluation result shows that the overall situation of the new type ofgovernment-business relationshipofthe 11 cities in Zhejiang province is good, butthe geographical discrimination is distinct and the differencesare obvious. Therefore, this paper proposes corresponding countermeasures to improve the performance of government's service and support to enterprises, and to build a clean government and a transparent government.
