"Construction industry" refers to the construction industry as a category of industry. Like "chemical industry", "petroleum industry", "steel industry", "machinery industry", etc., it is an industry first, and then it is an industry of different categories; "Construction engineering" first regards the construction industry as a "project" different from "industry", and then divides "construction engineering" into different categories such as "housing engineering", "civil engineering", and "installation engineering".
The construction industry emerged with the development of social producing countries and people's needs. As one of the three major industries, it is an important part of the national economy.
