It is the intent of the Legislature by the passage of this article to authorize the incorporation in any municipality of commercial development authorities to acquire, own, and lease projects for the purpose of promoting trade and commerce by inducing commercial enterprises to locate new facilities in any municipality and expand existing facilities in any municipality. It is intended that each project be self-liquidating. It is not the intent of the Legislature to authorize any authority itself to operate any commercial enterprise. This article shall be liberally construed in conformity with the intent.
