我国构建数字经济税收法律制度的现时难题和优化路径

传统税收法律制度在对数字经济企业实施税收征管时存在征管依据缺失、征管技术落后等不足,进而诱发税基侵蚀和利润转移问题,导致无法对数字经济进行充分有效的征管。各国对数字经济的利益诉求不同,使得在国际层面具备广泛共识的数字税方案难以达成。从国内层面来看,我国对于数字经济的税收征管仍旧依靠传统税收模式进行,并未将数字税作为独立税种在法律上予以确认。这种税收模式在数字经济持续发展的当下已经无法满足数字经济税收征管的现实需要。对于当前中国构建数字经济税收法律制度的路径,可以通过升级数字税收监管技术、发挥数字经济平台的监管作用和加强国际税收合作等手段进行优化,并积极参与和推进具有广泛共识的国际数字税收法律规则的制订。     

财政分权、政府竞争与企业税负

财政分权通过地方政府的税收竞争与支出竞争影响企业税负,其影响是中性的。利用沪深A股上市公司的面板数据,实证分析了财政分权对企业税负的影响,并考察了这种影响在不同性质企业间的差异。上市公司的税负整体上与财政分权程度呈U型关系,中央企业的所有权属性与企业税负没有显著关系,但地方国企与非国有企业的所有权属性与企业税负显著正相关。东、中、西部地区地方政府的竞争偏好差异,决定了财政分权程度与企业税负的U型关系。长期而言,应建立新型央地财政关系,赋予地方更多税权,合理引导地方政府间的税收竞争;短期而言,改进税制才是降低企业税负的关键。     

完善我国个人所得税制的思考

个人所得税是调节国家与个人利益分配关系的重要杠杆,随着我国经济的快速发展、居民收入水平的大幅提高,个人所得税将是一项最有前途、最有发展潜力的税种。但我国个人所得税政策不尽人意,执行起来既失公平,又欠效率。文章分析了我国个人所得税制存在的问题,提出了相应的对策。     

中小企业税务筹划探析

税收作为国家宏观经济调控的手段,调控作用愈来愈明显,为企业税务筹划提供了施展的空间,尽管中小企业税务筹划的主观愿望是为减轻税负,客观上却促进了中小企业在国家税收杠杆引导下,走优化产业的道路,反过来,对完善税法又起到了促进作用。使中小企业正视税务筹划、区分偷税、漏税以正确选择合法的税务筹划方法。     

“营改增”政策试点的市场初步评估

会计市场咨询表明,＂营改增＂政策是一个相当积极的信号,对于上海行业细分和服务外包的发展、尤其是总部经济的发展有重大的推动作用。但从政策实施的实际效果看：首先受益的是制造业服务业分离企业,部分服务企业实际税负尚未降低;部分中资企业对于政策的了解较为局限,不懂得如何从＂营改增＂中获益;没有完整会计账册的小微企业无法享受增值税抵扣带来的税负减轻,反而由此在同业竞争中与大中企业相比丧失了部分议价竞争能力。针对上述问题,应采取相应的对策措施逐步加以解决。     

Supply Chain Strategies and International Tax Arbitrage

What motivates the geographic footprint of the supply chains that multinational firms (MNFs) deploy? Traditional research in the operations and supply chain management literature tends to recommend locations primarily based on differentials in production costs and the ramifications of physical distance ignoring the role of taxation. MNFs that strategically position parts of their supply chains in low‐tax locations can allocate the profits across the divisions to improve post‐tax profits. For the profit allocation to be defensible to tax authorities, the divisional operations must possess real decision authority and bear meaningful risks. Generally speaking, the greater the transfer of risk and control, the larger the allowable allocation of profit. These transfers may also create inefficiencies due to misalignment of business goals and attitudes toward risk. We model these trade‐offs in the context of placing in a low‐tax region a subsidiary that oversees product distribution (as a limited risk distributor commissionnaire, limited risk distributor, or fully fledged distributor). Our analysis demonstrates that the MNF's preferences regarding the operating structures are not necessarily an obvious ordering based on the amount of risk and decision authority transferred to the division in the low‐tax jurisdiction. We derive and analyze threshold values of the performance parameters that describe the main trade‐offs involved in selecting an operating structure. We find some of the optimal decisions to exhibit interesting non‐monotone behavior. For instance, profits can increase when the tax rate in the low‐tax jurisdiction increases. Numerical analysis shows that the Limited‐Risk Distributor structure is rarely optimal and quantifies when each alternative dominates it.     

分税制以后我国财权配置问题实证研究

1994年推行的分税制是不彻底的,财权配置缺乏协调性和统一性,致使各级政府在公共产品和服务提供中责权利不对称。因此,需要调整财权配置,以保证事权和财权的统一。     

Missing item imputation for quality-of-life instruments with application to asthma quality-of-life questionnaires

There has been increasing use of quality-of-life (QoL) instruments in drug development. Missing item values often occur in QoL data. A common approach to solve this problem is to impute the missing values before scoring. Several imputation procedures, such as imputing with the most correlated item and imputing with a row/column model or an item response model, have been proposed. We examine these procedures using data from two clinical trials, in which the original asthma quality-of-life questionnaire (AQLQ) and the miniAQLQ were used. We propose two modifications to existing procedures: truncating the imputed values to eliminate outliers and using the proportional odds model as the item response model for imputation. We also propose a novel imputation method based on a semi-parametric beta regression so that the imputed value is always in the correct range and illustrate how this approach can easily be implemented in commonly used statistical software. To compare these approaches, we deleted 5% of item values in the data according to three different missingness mechanisms, imputed them using these approaches and compared the imputed values with the true values. Our comparison showed that the row/column-model-based imputation with truncation generally performed better, whereas our new approach had better performance under a number scenarios.     

中国房地产税制:存在问题与改革设想

在现代市场经济条件下,房地产税制具有十分重要的功能。现阶段中国房地产税制存在房地产税收功能分散,房地产税种设置交叉重叠现象突出,计税依据不符合国际惯例,房地产保有环节税负偏轻和房地产税权分布结构不合理等问题。中国房地产税制改革已进入基础性制度建设阶段,必须按照"宽税基、简税种、低税率"的原则,实现房地产开发流转环节税收为主向房地产保有环节税收为主的房地产税制转型,去土地财政化,这就要适时开征房产税。开征房产税可以分两步走,近期对居民新购商品房超免税标准部分征收房产税,中长期覆盖到居民已购存量房地产。     

全球化进程的正反方、分野及其转化

本文试图从国际政治经济学的视角考察全球化之动力与反冲。全球化既造就了赢家,也产生了输家。有理由认为,那些从全球化进程中获益相对较多的国家或社会群体,将成为全球化的坚定支持者,从而推动进一步的开放。反之,那些因全球化而受损的国家和群体,很可能成为全球化的反对力量。尽管如此,赢家与输家的分野并非一成不变。如果各国政府能够以行之有效的政策手段来调和赢家与输家之间的分歧和对抗,那么全球化面临的反对力量就有可能被转化为动力。
