Objectives We sought to investigate and evaluate bronchoconstrictor response to provocation by histamine in healthy adults by volumetric capnography, and to compare the relation between volumetric capnography and the standard methods of measuring bronchial responsiveness. Methods Forty healthy adult subjects(median age,35;range,31.95 to 10.66 years) received bronchial histamine provocation test using an automatic

全面征收房地产税对调控中国房地产市场具有重要意义。现有的文献主要研究单一房产税政策的影响,尤其是现行房产税政策的影响,尚未针对现行房产税政策与未来全面征收房地产税政策的不同影响进行研究。论文从住房消费者的角度出发,通过对比现行房产税政策和未来全面征收房地产税政策下居民的购房意愿变化,研究了全面征收房地产税对居民购房意愿的影响。通过分析随机抽取的上海市11个中心城区共21个居民小区901份问卷的调查数据,发现:相对于现行房产税政策,全面征收房地产税会抑制居民的购房需求。具体来说,对房地产税认可程度越低、预期房地产税会抬升房价以及拥有房产越多的居民,在全面征收房地产税后购买房产的概率越低,即全面征收房地产税会更多地影响这些居民的购房意愿。此外,年龄分布在18-25和41-50岁两个年龄段、收入在30-100万、学历为本科的居民,由于受收入水平、购房和持房成本等原因影响,全面征收房地产税会改变其购房意愿。因此,未来全面征收房地产税,政府需要明确不同特征居民的住房需求,保证居民的基本需求不受房地产税政策的影响。

【问题】公共选择理论表明,联邦体制下政府间竞争会减少民生服务供给,但我国地方政府债务竞争并不会直接导致民生服务的减少,相反,债务规模越高,人均公共服务水平也越高。因此,应如何解释我国地方政府债务竞争与民生服务供给的内在机理?【方法】本文基于2013—2017年222个地级市的面板数据,通过构建不同的空间权重,运用空间杜宾模型分析了政府间债务竞争对民生服务供给的影响及内在机理。【发现】(1)同省内地级市政府债务竞争存在空间溢出效应,会增加本地区民生服务供给。(2)同省内地方政府债务竞争可以提升全省范围内民生服务供给。(3)从服务类别看,同省地方政府债务竞争会促进本地区在教育和医疗两类民生服务的支出,但并不会促进社保的支出。【贡献】城投债可以满足地方政府生产性公共品的资金需求,间接增加地方政府预算内民生服务供给的资金。在我国行政发包制债务治理机制下,政府间债务竞争最终会促进同省内地级市政府民生服务的供给。在中国制度背景下对这一问题的研究丰富了传统的公共选择理论。
