delivered the opinion of the Court.
This is an appeal from a judgment of the Denver District Court enjoining the City and County of Denver from requiring electrical *183 contractors and electricians licensed by the state to obtain city licenses. We affirm the judgment of the trial court.
In 1975, the Colorado legislature enacted section 12-23-111(15), C.R.S. 1973 (Supp. 1976), which established exclusive state licensing of electricians. Declaring such licensing to be a matter of state-wide concern, the statute prohibited all local governmental authorities from requiring local licenses for electricians licensed by the state. Denver contended, however, that as a home-rule city, its licensing ordinances superseded the conflicting state statute, and the city refused to issue an electrical permit to an electrical contractor and a master electrician who held state but not Denver licenses. Thereupon, the suit was instituted in the district court to enjoin Denver from requiring a local license.
Article XX, section 6, of the Colorado Constitution contains a broad grant of governmental authority to home-rule cities to enact charters to control their “local and municipal matters.” The section provides: “Such charter and the ordinances made pursuant thereto in such matters shall supersede within the territorial limits and other jurisdiction of said city or town any law of the state in conflict therewith.”
While this provision established exclusive home-rule over matters of local concern, statutes dealing with matters of state-wide concern operate to the exclusion of conflicting local ordinances.
See, e.g., Bennion
v.
Denver,
A legislative determination that a matter is of state-wide interest is entitled to great weight,
see Denver
v.
Tihen, 11

(1925). In making such a review, this court must consider the changing needs of the people of the state and the impact of the regulation.
See People
v.
Graham,
However, even where there is a demonstrable local interest, as well as a state interest, a home-rule city does not by virtue of Article XX derive preemptive authority.

The judgment of the district court is affirmed. '
