  Taking advantage of nearly 4 million transition records for three years in
London from a popular location-based social network service, Foursquare, we
study how to track the impact and measure the effectiveness of cultural
investment in small urban areas. We reveal the underlying relationships between
socio-economic status, local cultural expenditure, and network features
extracted from user mobility trajectories. This research presents how
geo-social and mobile services more generally can be used as a proxy to track
local changes as government financial effort is put in developing urban areas,
and thus gives evidence and suggestions for further policy-making and
investment optimization.
