He submitted his nomination on 16 February, with 641 of the 796 Election Committee members nominated him which guaranteed his electoral victory before the polling day. He faced challenge from the pan-democrats who backed Civic Party legislator Alan Leong to run against him. Tsang was elected by the 796-member Election Committee on 25 March 2007 with 649 votes, compared to Leong's 123 votes. It was seen as the first competitive Chief Executive election featuring two candidates from different political camp with debates held between the candidates which changed Hong Kong's political culture.

He also proposed a series of revitalisation projects that would add a new dimension to Central. For instance, to reduce the development density of the Central Ferry Piers site and open up the public space along the waterfront for entertainment, recreational and cultural uses; to remove the Central Market from the Application List and hand it over to the Urban Renewal Authority for conservation and revitalisation; and to convert the Murray Building into a hotel through open tender
