An evidence-based planning support methodology estimating value creation of planning scenarios in the chinese context

In the transition to a market-driven post-industrial society, China's urban planners are dealing with sustainability issues such as reducing environmental pollution while maintaining urban growth. To realize such sustainability goals, planners can make use of the market force to create value for both endusers (residents) and investors (governments and developers). However, the current planning approaches hardly support planners to estimate value creation by planning decisions. This article considers the city-wide effects of planning interventions and proposes an evidence-based planning support methodology to assist planners estimating value creation of planning scenarios. It illustrates the methodology with two planning scenarios in Nanjing China. Results show that new metro construction will influence land prices city-wide instead of just within the direct vicinity of the new metro lines. And redevelopment of heavy industrial areas will have a spill-over effect beyond the redeveloped areas. This methodology can help planners to estimate the city-wide value creation by planning interventions.
