    纳税评估是税收管理的重要内容和不可缺少的管理环节。国内外的实践表明,纳税评估在加强税源管理、降低纳税人涉税风险、增加税收收入等方面发挥了日益重要的作用。在国内,由于对纳税评估的客观规律性在不断认识和探讨之中,加上纳税评估制度的建立和具体实施时间不长,其重要作用还没完全得到发挥,并存在法律保障不足、制度保障不足、机构人员保障不足及信息化保障不足等亟待解决的问题。这些问题在基层国税部门开展纳税评估的具体实践之中也普遍存在。因此,加强对基层国税部门纳税评估研究,对进一步发挥纳税评估的职能作用,完善税收管理制度,有重要的现实意义。 本文结合当前工作实际,从理论、实践两方面对基层国税的纳税评估工作进行...Tax assessment is an important part of tax management and an essential management process. Domestic and international practice shows that, tax assessment increase in tax revenue, strengthen the management of sources, reduce the tax risk has played an increasingly important role.

    我国房地产行业经过多年的发展,房地产开发投资模式已经比较成熟,房地产开发企业主要是通过招标、拍卖或挂牌(简称招、拍、挂)方式获得土地用于房地产开发。但在深圳,由于土地资源十分有限,多数房地产开发企业无法通过招、拍、挂方式获得可开发的土地。为了应对土地资源供应不足的问题,早在2009年,深圳首次在全国提出“城市更新”概念,以市场化手段对城中村、旧工业区等存量土地进行二次开发,并允许以协议出让的方式出让土地使用权。在此背景下,传统的房地产开发投资模式在深圳已退为次要地位,取而代之的是集体土地开发(非农建设用地与征地返还用地项目投资)和城市更新项目投资,这一特点显著有别于全国其它城市。但由于开发程序...After many years of urban development, Chinese real estate developers obtain land mainly through biding, auction and listing. But Shenzhen real estate developers cannot grab land through biding, auction and listing because of severe shortage of residential land supply.

    疝气,是人体组织或腹内脏器离开原来正常部位通过人体间隙、腹壁上的缺损或薄弱位置,转移到其他部位。目前,临床上主要通过外科手术和人工补片来修补疝气,每年大约有50万人接受疝修补手术。大部分腹股沟疝能通过人使用工合成补片达到修复目的。腹股沟疝无张力修补术中应用不可降解聚合物补片以增强腹股沟腹壁薄弱区,虽然显著降低了传统腹股沟疝手术的复发率,但不可降解补片易使患者出现慢性疼痛、补片感染和精索损伤等并发症。基于前期研究,我们以羊主动脉为原材料,通过物理或化学的方法有效去除细胞、活性蛋白成分,从而有效降低材料的免疫原性,再经过冻干灭菌等工艺处理,制备出一种新型的脱细胞基质材料。脱细胞后的支架仅保留了胶原...A hernia is defined as the exit of viscera, such as the bowl, through the wall of the cavity or defects in which it normally resides.

    二噁英类化合物(Dioxin-likecompounds)是典型的持久性有机污染物,它们对生物体具有强致癌、内分泌干扰、肝毒性、免疫毒性、皮肤毒性、生育障碍等健康威胁,因此对它们的监控就显得极为重要。目前对二噁英类化合物的分析方法多种多样,但总的来说可以把它们归结为仪器分析法和生物分析法。其中仪器分析法样品前处理过程繁琐,检测周期长,检测成本昂贵,同时对检测人员的技术要求也比较高,限制了该方法在环境监测中的应用。由于二噁英类化合物具有相似的毒性机理,均能通过AhR信号通路影响cyp1a1基因的表达,因此我们设计并构建cyp1a1启动子调控GFP基因的方式,获得稳转的HepG2细胞系与转基因斑马...Dioxin-like compounds (DLCs) are typical persistent organic pollutants that have a health threat to the organism with strong carcinogenic, endocrine disrupting, hepatotoxicity, immunotoxicity, skin toxicity, and fertility disorders, so monitoring them is extremely important.

    在数量型货币政策框架下,法定存款准备金是重要的货币政策工具。但随着货币政策框架由数量型转向价格型,法定存款准备金的作用不断弱化。以英国、加拿大为代表的一些利率调控国家已经将法定存款准备金降为零。 本文首先介绍了货币政策调控中介目标的理论框架,主要分为数量型中介目标、价格型中介目标、普尔的择机中介目标理论,在此基础上探讨了美国、英国、德国、巴西等国家的货币政策中介目标转型实践。 其次,通过比较分析美国、英国、德国和韩国四个国家在货币政策框架转型过程中法定存款准备金制度变迁,指出随着金融深化和货币调控方式转变,法定准备金率的下降是必然趋势。 再次,本文对正在货币政策框架转型道路上的中国的法定...Under the framework of quantitative monetary rule, the required reserve system is one of the most important monetary policy tools.
