All organizations involved in services concerning foreign affairs conduct their work publicly in time-limited service. There are government bodies devoted to investors. These institutions are the Guizhou Provincial Investment Promotion Bureau, Guizhou Provincial Service Center for External Investment and the Guizhou Provincial Complaint Center for External Investment. There are one-building institutions in nine prefectures, cities and national-level or provincial-level development zones where investors can enjoy highly-efficient and convenient services.

The investment environment of the province should be monitored and publicized in due time. An evaluation index system for the provincial investment environment has been set up that will supervise and assess the investment environment in different prefectures and development zones. The results will be publicized in the media for investor reference and provide scientific evidence to constantly improve the investment climate in these places.
