本文基于2013年开展的农业部农村固定观察点"‘三农’政策执行情况"农户调查数据,利用有序Probit模型从基础设施建设、土地整理等角度考察了农村政策执行协商对农民政策满意度的影响,并借助双变量有序Probit模型减轻了可能存在的内生性的问题。研究发现,扩大农户参与政策执行协商,对农户的政策满意度有显著的正向影响,该结论从检验方法、变量定义等方面均具有很好的稳健性。研究表明,完善农村基层协商民主制度,推进村级事务的农户协商,能有效缓解农村社会张力,避免激化基层社会矛盾,提高农村公共治理水平。

本文全面梳理新加坡"白地"规划的实施背景与制度,并以具体项目为例全面展示白地规划通过土地预留、混合利用、用途转换和土地溢价让利激发地区发展活力和应对市场不确定性的作用。国内对新加坡白地规划管理的经验引介已久,也已有一定的本土化实践,但真正实现精细化的白地规划极少,其主要原因是中新城市因发展阶段不同而存在应用机制差异,主要体现在规划体系、土地经济和开发经验等方面。在中国迈入城市高质量发展、空间精细化治理的规划阶段后,上述应用机制差异逐步缩小,关键地段进一步应用白地规划具有必要性和可行性,应满足法定规划严肃性和存量规划时代的发展需求,促进产业地块效益最大化开发、公共设施用地弹性预留和城市精细化治理水平的提升。

对含有各向异性层的多层结构中波传播问题的数学描述非常复杂,这一复杂性源于界面的多样性和各向异性介质物理性质的特殊性.针对此问题,基于传递矩阵方法,以界面为刚性连接的各向同性/正交各向异性/各向同性3层结构为例,导出了此类结构中SV波和最低阶模态SH波(即SH0)的反射与透射系数表达式.利用数值模拟研究了入射角度、频厚积和中间层介质对横波传播特性的影响.结果表明:SV波入射多层结构会有临界角存在,SH波入射无此现象.当声波垂直入射,随着频厚积的增大,多层结构中SV和SH波的反射和透射系数曲线会产生多阶谐振.研究结果为实际实验中采用横波入射检测类似于各向同性/正交各向异性/各向同性的多层结构提供了理论依据.

已有研究揭示共享城市是一种正在走向实现的人类文明智慧和可持续发展观紧密结合的理想城市新范式,但目前也存在负效应探讨不足,以及作为城市整体的实践机制研究不足的缺失。在对共享城市概念推动的国内外代表案例进行梳理分析基础上,总结出当前人们主要运用政策制定、空间设计和活动策划的手段,促使城市的实物、空间、服务和技术资源产生更深层次的连接与使用,为城市问题创造更有效率和具有可持续发展潜力的解决方案。综上提出三方面的前瞻性思考:一是建立"充分共享"的规划空间认识,从空间盲目扩张和功能一刀切的旧发展方式转变为对有限空间资源的精细化经营;二是填补"约治共享"的规划管理空白,限制共享经济的非理性空间扩张与负面影响,从制度层面建立新兴共享空间的监管机制;三是创新"激活共享"的规划设计策略,在城市开发中创造更多共享可能的城市空间资源,在城市修补中创造更加紧密交往的居民社会网络。
