In the wave of globalization, central parts of large cities are growing
exponentially. As the phenomenon is expected to continue, the city and the
state are expected to compete with each other in the future. However, the
main factor that influences urban competitiveness, construction of
infrastructure, continues to put decision-makers in cities in a dilemma.
This paper uses data from the national bureau of economic analysis, the World
Bank and the OECD to analyse the relationship between urban infrastructure
investment and GDP, infrastructure investment as the proportion of real
estate investment, the relationship between urban infrastructure
construction investment and urbanization rate and per capita GDP. The above
analysis leads to the finding that the channels match with all kinds of
urban infrastructure investment and financing. Moreover, under perspective
of cost management, the choice of investment and financing channels is
analyzed. Simultaneously, the corresponding processes, principles and
requirements in cost management are elaborated. This paper provides
references for countries choosing different investment and financing
channels.
