Livability Assessment of Urban Communities considering the Preferences of Different Age Groups

الملخص EN

Livability is one of the major guiding principles for urban planning and policymaking, of which the definition and evaluation have become the crucial research topic.

As the progress in socioeconomic development accelerates, the microscale living conditions require more urgent attention.

However, few researchers have addressed the assessment of urban livability at a finer spatial scale such as the community scale.

Thus, this article aims to evaluate the urban environmental quality at the community level given the residential community as the basic unit of urban living areas.

We select eighteen objective indicators from five dimensions to establish an objective indicator system.

Taking the preferences of different age groups into account, a comprehensive evaluation framework for the livability of communities combining both subjective perceptions and objective indicator is constructed.

Then, it is applied to evaluate the livability of 1,394 residential communities in Ningbo City.

There are three significant results from the study.

First, different age groups have diverse preferences of demands to the livability of an urban community.

The indicators they valued most concentrated in the following two dimensions: the convenience of transportation and the completeness of supporting facilities.

Second, there exists significant heterogeneity in the livability of communities among districts.

Third, the livability of communities shows a decreasing spatial pattern from the city center to the surroundings.

These empirical results can be advantageous to urban planning departments and other relevant stakeholders.
