Abstract：Urban renewal is important in meeting the daily needs of residents and activating the vitality of the city. In the historical
and cultural districts, the renewal should take into account the cultural connotation of the site, continue the production
and living activities, make full use of the resources, and make protective use of the old buildings. Taking the planning
and design program of the National Territory Development Contest for College Students in Anshan Road district in
Tianjin as an example, starting from the renewal of historical and cultural districts based on the catalyst theory, the
study tries to carry out in-depth exploration in the aspects of analysis of the site problems, selection of the catalyst elements
and control of the catalyst reaction. And then, combined with micro-renewal, participatory planning and other
methods, the study hopes to solve the problems in this district: lack of space inconveniences of the living; poor business
types, difficulty in coordinating multiple interests, and ultimately tries to summarize a strategy of using the catalyst theory
comprehensively in the renewal of historical and cultural districts.
