本文首先对2008年-2016年28个省的居民部门、地方政府部门和非金融企业部门杠杆率进行了详细测算,并基于该数据使用门槛回归模型,来研究省级分部门杠杆率对于经济增长的影响。研究发现:各省的地区经济发展水平、地方政府治理水平、金融规模、投资率、通胀率和城镇化在杠杆率对经济增长起到影响的过程中存在显著的门槛效应,从而各省不同的初始条件,决定了在不同省份、不同部门实施"去杠杆"政策的异质性经济效应。据此,建议各省结合本地实际的初始条件,因地制宜地发挥不同部门杠杆率对经济可持续增长的动力。各省均不应降低居民部门的杠杆,而"去杠杆"的重点应放在去低政府治理水平地区、或低金融规模地区、或低GDP增长地区的非金融企业部门杠杆,以及去低通胀地区的地方政府杠杆。

A critical challenge to the commercialization of clean and high-efficiency solid oxide fuel cell(SOFC)technology is the insuf-ficient stack lifespan caused by a variety of degradation mechanisms,which are associated with cell components and chemical *** components related degradation refers to thermal/chemical/electrochemical deterioration of cell materials under operating conditions,whereas the latter regards impurities in feedstocks of oxidant(air)and reductant(fuel).This article provides a thermodynamic perspective on the understanding of the impurities-induced degradation mechanisms in *** discussion focuses on using thermodynamic ana-lysis to elucidate poisoning mechanisms in cathodes by impurity species such as Cr,CO_(2),H_(2)O,and SO_(2) and in the anode by species such as S(or H_(2)S),SiO_(2),and P_(2)(or PH_(3)).The author hopes the presented fundamental insights can provide a theoretical foundation for search-ing for better technical solutions to address the critical degradation challenges.
