To deal with various risks in the production of space,local governments have to cease the monopolization in land requisition and expropriation,and establish the balance of interests between correlative groups and national institutions in the circulation of lands.To deal with risks in the games of new society,local governments must adjust the systems and policies concerned,and avoid just scratching the surface of a problem.To deal with risks in reallocation of social resources and social administration concerned with policy output,many local governments already have material condition to effectively break them,and the key is to improve their administerial skills in policy making and implementation.To deal with risks in vicious competition between city governments in urbanization,which are actually the manifest of malfunction of market mechanism,local governments must put the centralization mechanism into full play,and strengthen the social check and balance mechanism,in order to effectively regulate market mechanism and realize the organic interactions between social units,democracy,and market.

要破解地方政府在空间生产中风险重重的局面，必须改变政府在土地征用征收上的独裁专断格局，完善土地流转中各个相关利益群体间的权利均衡以及国家机构间的权力均衡机制；地方政府在新型社会博弈中的风险，也需要相关制度与政策的调整，不能停留在治标不治本的层次；在社会资源再分配与社会管制等政策输出方面的风险，许多地方政府已经具备了有效化解的物质条件，主观上提高政策制定与执行的行政技能是解决此类问题的关键；我国城市政府在发展地方经济推进地方城镇化中的恶性竞争风险，本质上是市场机制失灵的一种表现，必须通过充分运用集权机制、强化社会制约机制从而有效规制市场机制，实现科层、民主、市场三种机制的良性对接，政府、社会、企业三种力量的有机互动，才能解决。
