我国城市公共服务存在重供给改进轻需求表达的倾向,导致公共服务供需错位和有效需求的供给不足。依据谁之需求、如何表达、哪些需求与何以满足的发展逻辑,公共服务的需求表达机制包括主体筛选机制、需求整合机制、需求识别机制与需求吸纳机制。为了实现公共服务的精准化、适配性和有效化,需要将自上而下的公共服务决策与自下而上的需求表达结合起来,实现供给决策与需求表达的无缝对接与融合。 The urban public service in our country has the tendency of heavy supply to improve the expression of light demand, resulting in the supply shortage of public service and the insufficient supply of effective demand. According to who needs, how to express, what needs and how to meet the development logic, the public service demand expression mechanism includes the main body screening mechanism, demand integration mechanism, demand recognition mechanism and demand absorption mechanism. In order to achieve the precision, adaptability and effectiveness of public services, it is necessary to combine top-down public service decisions with bottom-up demand expressions to achieve a seamless connection and integration of supply decision-making and demand expression.
