Huayang Industrial Cluster has independent county-level economic management authority, and can handle the procedures of project establishment, planning, land use, environmental assessment and safety assessment of enterprises in the cluster. At the same time, industry and commerce, taxation, land and other related units have offices in the cluster. We implement a free agency service system for enterprises, one-stop office and lifelong service. For each project, we will strictly implement the six-one tracking service responsibility system of "one project, one leader in command, one department in charge, one working group to implement, one implementation plan to promote and one liaison person to communicate" to create an excellent external environment for the project.
