本章首先从宏观、中观和微观三个层面入手研究了推进关中城镇体系协调发展的相关机制：（1）宏观层面重点研究了政府行为对关中城镇体系发展的影响，认为在不同制度环境下地方政府行为选择也是对其它主体行为选择的理性反应，但地方政府行为能否趋于理性化并有利于关中城镇体系的协调发展，关键还是在于尽快完成关中体制创新和制度创新的基础上，规范政府行为，建立有助于地区利益协调的宏观调控体系，并以此为基点确定了关中城镇体系的宏观调控目标与重点；（2）中观层面重点从产业组织和区域经济空间组织两个方面分析了推进关中城镇体系协调发展的产业聚集机制和各城市经济区的区内组织及区际协调机制；（3）微观层面从企业、非政府组织和公众三个方面入手。分析了微观主体的行为特征及其参与关中城镇体系协调发展的积极作用，并建立了促进微观主体主动参与的激励—约束相容机制。

In this scheme, the description of unitary evolution and quantum measurement is unified and the quantum control operation is represented by probability state transition. The algorithm works as follows. At first a measurement is applied on the system. If the state after collapse is not the desired eigenstate, then system evolution will go on. After a period of time, the system is measured again. The process will go on like this until we get the desired eigenstate by measurement. Finally the system is driven to the target state with admissible control as before.
