In regional development, geography should not restrict its applied studies to comprehensive survey, regionalization and planning. It should also take part in policy research and play a role of brain trust.It is very important for geographers to make policy research in regional development: (1) Promoting planning -implementation; (2) Raising the status of geography in social practice; (3) Improving the academic level of geography; (4) Strengthening the rationality of policy.Geographers Can make policy research in two aspects. First, evaluating the effects of policy and predicting its positive and negative influences in the future. Second, putting forward specific suggestions for policy-makers to modify the present policy and formulate a new one.The policy in regional development has the basic features of localizability, phasibility, and relative stability.Geography should focus on the comprehensive policies related to natural, economic and social factors, such as resources exploitation and utilization policy, environmental protection policy, and production allocation policy.
