Firstly,this paper discussed differences between traditional urbanization and new urbanization. Then,from current situations of financial support for new urbanization,it analyzed existing problems in financial support for new urbanization. The problems include difficulty in infrastructure financing,shortage of funds for small and medium sized enterprises,narrow scope of financial services,and uneven industries of financial support. Finally,it came up with pertinent recommendations,including implementing diversified infrastructure financing modes,solving financing difficulty of small and medium sized enterprises through many channels,strengthening service level and expanding service scope of financial institutions,and changing the situation of uneven industry of financial support,in the hope of providing helpful references.

随着数字技术更迭推新,数字普惠金融迎来了跨越式发展,其零距离接触长尾客户群体、提供低价便捷的服务,延伸了金融服务半径,满足了中低收入家庭的借贷需求,对居民杠杆率的传导效应不容忽视。本文利用2011—2018年北京大学数字普惠金融发展指数与我国30个省(自治区、直辖市)的相关经济数据,采用固定效应模型实证检验数字普惠金融发展对居民杠杆率的影响。研究结果表明:(1)数字普惠金融发展对居民杠杆率产生正向影响。分维度来看,数字普惠金融发展主要通过覆盖广度和使用深度对居民杠杆率产生正向影响。(2)异质性检验结果显示,数字普惠金融发展对居民杠杆率的影响随着杠杆率分位数水平的上升而下降;数字普惠金融发展对西部地区和中高收入群体影响程度较大。本研究的发现为认识居民杠杆率成因提供了新的证据,也为有关部门分类施策管控居民杠杆率提供了经验证据。

A rapid and efficient procedure,the STE(sodium chloride-Tris-HCl-EDTA) method,for isolating high quality total RNA from polysaccharide-rich mycelia of the edible fungi Lentinus edodes,Ganoderma lucidum and a Polyporus *** *** quality of the total RNA isolated by the STE method was superior to that obtained using the Trizol *** A260/A280 and A260/A230 ratios of RNA isolated by the STE method ranged between 1.80～2.10 and between 1.90～2.30 respectively,whereas the A260/A280 ratio of RNA isolated by the Trizol method was below 1.80,and the A260/A280 ratio was outside the 1.90～2.30 *** distinct bands representing 28S,18S and 5S rRNA were observed following electrophoresis of total RNA isolated from the three test strains by the STE *** of total RNA isolated using the Trizol method resulted in dark bands corresponding to 28S rRNA and 18S rRNA,indicating partial degradation of the *** data demonstrated that the total RNA isolated by the STE method was of a quality eminently suited for downstream applications.
