An experiment-based policy-making model based on China's experience attempts to reconcile such debate by arguing that policy makers can consciously make policies without deliberately designing them. That is, policy makers can encourage or initiate multiple small-scale experiments that will cumulatively translate into incremental policy changes. Through a case study of urban housing policy changes in China, this paper investigates the underlying logic of incremental policy changes, specifically the role of policy makers in successive policy experimentation. Our case study illustrates that the role of local policy experimentation has been overestimated because the central government controls the experimental variables, judges what constitutes the success of the experiment, and chooses which experiments are replicated at the national level. 收起
