Some Comments on Tax Competition and Its Potential Effects on Tax Rates and Revenues

Corporate taxation is seen as the price of investing in a country, that is, the price either for the right to do business within the jurisdiction or for the supply of public goods. If consumption of that right or those public goods is mobile between jurisdictions and price competition ensues which will force prices together. Also, in the case of high tax regimes, a fall in the tax burden would be anticipated. In other words, countries will spontaneously harmonize their tax systems or face the loss of intemational investment and the disadvantages they bring.

沉默MPZL1调控β-catenin对A549/Tax细胞干性及耐药性的影响

目的探讨髓磷脂蛋白零样蛋白1(MPZL1)沉默后是否通过调控β-catenin表达对A549/Tax耐药性和细胞干性产生影响。方法采用不同浓度阿霉素和紫杉醇处理A549和A549紫杉醇耐药性(A549/Tax)细胞,观察两种细胞的耐药性差异。实时荧光定量聚合酶链式反应(qRT-PCR)和Western blot检测A549和A549/Tax细胞中MPZL1的表达量差异。对A549/Tax细胞沉默或者过表达MPZL1,进一步将细胞分为对照(control)组、短发卡RNA阴性对照(sh-NC)组、MPZL1沉默(sh-MPZL1)组、过表达阴性对照(OE-NC)组、MPZL1过表达(OE-MPZL1)组,运用细胞计数试剂盒8(CCK-8)和平板克隆实验分别检测MPZL1的表达变化对A549/Tax细胞增殖和克隆形成能力的影响。Western blot检测Wnt/β-catenin抑制剂XAV939和激活剂CHIR-99201处理细胞后,不同蛋白的表达变化。结果A549/Tax细胞对阿霉素和紫杉醇的半数抑制浓度(IC 50)较A549细胞明显增加(P<0.01)。MPZL1在A549/Tax中呈更高的表达趋势。MPZL1敲除后A549/Tax对阿霉素和紫杉醇的IC 50分别为2.731 mg/ml和4.939μg/ml,较阴性对照组的4.541 mg/ml和13.55μg/ml降低(P<0.01)。CCK-8和克隆形成实验结果显示,MPZL1敲除抑制肺癌A549/Tax细胞的增殖活力和克隆形成能力(P<0.05);Western blot结果显示,与阴性对照组相比,MPZL1、肿瘤干性相关蛋白(CD44和CD133)、多药耐药蛋白1(MDR1)、肺耐药相关蛋白(LRP)和β-catenin在sh-MPZL1中的表达水平明显减少(P<0.01)。此外,XAV939可抑制MPZL1、CD44、CD133、MDR1、LRP和β-catenin的表达。CHIR-99201处理细胞后部分逆转敲除MPZL1对上述蛋白的抑制作用。结论MPZL1在肺癌A549/Tax细胞中高表达。敲除MPZL1可抑制肿瘤干性和细胞增殖,增强肺癌A549/Tax细胞对阿霉素和紫杉醇的敏感性。

Research on Tax Revenue Flexibility Based on the Perspective of Central Tax in Chongqing

The paper did an empirical research on national tax revenue flexibility in Chongqing from the total and structural perspectives, and it shows that there are some fluctuations during 2005-2009, which are still within a normal range. Tax revenue promotes Chongqing's economic growth.

Why Has China's Tax Revenue Doubled the GDP Growth Rate in the Past 13 Years?

After 12 years’ sustained and rapid growth,China’s tax revenue is exhibiting a more robust increasing trend at the beginning of the 11th Five-year Plan period,which has aroused more significant implications for macroeconomic operation and the overall economic and social development course.Starting from an analysis of the relation between tax revenue and current tax system,the paper intends to find out the unusual factors supporting China’s sustained and rapid tax increase.On this basis,the paper provides policy judgments and puts forward relevant policy recommendations.

Sustainability of China＇s Tax Revenue Growth： Experience and Prospect

This paper summarizes the main characteristics of China＇s tax revenue growth during the period of 1994-2010, and probes the causes behind the sustained and rapid growth of China＇s taxation from its sources including the fiscal and taxation system, and tax collection mechanisms. Additionally, the author lists the major challenges confronting China＇s sustainable tax growth during the ＂12th Five-Year Plan ＂period （2011-2015）, for example, slowed growth in sources of taxation, a mismatched tax system, lagging reform in fiscal structure and the management system, and restrictions in tax collection and administration capacity. The author proposes the following suggestions： 1） a structural taxation reform should be carried out to promote sustainable economic growth and a change in development model, thereby consolidating the source base of taxation; 2） to consolidate the fiscal and taxation system through taxes and fees reform, standardizing the government budget, advancing reform in the tax-sharing system, and optimizing fiscal expenditure; and 3） to strengthen tax collection mechanisms by promoting taxation by law, implementing comprehensive taxation administration in the government, and improving the tax collection capacity.

Empirical Test of Wagner＇s law in New Public Management Countries＇ Tax Revenue

The essence of empirical test of Wagner characteristic in new public management countries＇ tax revenue is to test the influence of economic growth on tax growth since new public management movement. Under IMF statistical framework, by using E-G two-step method in co-integration test and Granger causality test and empirically testing of the gross tax revenue and classified tax revenue in Australian, Canada, France, America, Britain these five countries, we can find that most indicators in most countries do not confirm to Wagner＇ s law. With the growth of GDP, tax revenue as a percentage of GDP rises periodically but not permanently. This period can be called the validity period of Wagner＇ s law in financial scale.

Environment, Health and Economic Growth： Study on Optimal Energy Tax Revenue Distribution

Under the dual pressures of economic growth and environmental protection,how to curb pollution and raise public welfare without harming the economy or with minimal economic output losses has become a major question facing China in its efforts to transform growth pattern and accomplish economic transition. On the basis of an overlapping generation(OLG) model, this paper introduces the health effects of environmental pollution to systematically discuss the optimal distribution ratio of energy tax revenues in subsidizing household income and emission abatement under given tax rates to reduce the risks of "environment-health-poverty" trap. Our research shows that an optimal distribution ratio for maximizing per capita output or an optimal distribution ratio for maximizing public welfare exists. Based on China's actual parameters, however, this study has found that China's energy tax revenue distribution policy hardly meets the two optimal targets at the same time. Specific distribution ratio is subject to government decision-making preference, and needs to be adjusted according to actual differences.

Discussion on the Improvement of Management System of Government＇s Non-tax Revenue

With the establishment of the aim of public finance, the non-tax revenue management causes extensive concern of both academy and government in recent years, around which the policy of fee-to-tax reform and income-expenditure going different ways etc. was launched. How to manage the non-tax revenue, which constitutes an important part of the public revenue, plays an important role in the rationalization of public revenue and the building of the public finance system. This paper uses international experience as reference to analyze the situation of the current non-tax revenue management, and the innovation of non-tax revenue management mode from both theoretical and practical aspects.

Potential Fiscal Revenues From Hydrocarbon Extraction for the Tourism Region of the Canary Islands

Hydrocarbon exploration that recently took place in the Canary Islands has triggered a controversy over the compatibility between these activities and tourism. Such exploration was strongly rejected by the region, while being supported by the Spanish government. Many environmental and economic impacts of hydrocarbon extraction were explored, except the fiscal revenues, which represent the main benefit for the producing economies. In this paper, the author addresses this missing piece in the controversy, namely, the assessment of fiscal revenues from hydrocarbons for the Canary Islands. To evaluate these revenues, the author estimates an oilfield production profile, constructs oil and gas price scenarios, and considers the new Spanish tax on hydrocarbons. The estimates are also placed in the socio-economic context of the archipelago. The results show less than overwhelming annual fiscal revenues, below 0.7% of GDP, 10.4% of current public transfers to the region, and 5% of current public spending in 2015. These revenues could be welcome, as the region lags behind the rest of the nation in living standards. However, these benefits from exhaustible resources must be compared to the potential damage to the tourism sector, which has been a long-standing economic driving force for the archipelago.

Taxing sugar-sweetened beverages in China:By volume or sugar content? A consumer welfare approach

Using scanner data on the consumption of packaged liquid beverages by Chinese urban households,we estimated the price elasticity of various beverages and compared the effects of volume-based versus sugar-content-based taxation strategies on consumer welfare.Compared to the volume-based tax,the sugar-content-based beverage tax was predicted to cost less in compensating variation under the same amount of sugar reduced,indicating that taxation based on sugar content may be more efficient in preserving consumer welfare.Further comparison across different socioeconomic groups reveals that,given current beverage consumption status in China,the efficiency advantage of the sugar-content-based taxation strategy is more pronounced than that of the volume-based taxation.Our conclusions can provide insights for the food industry and the government to reduce the sugar content in beverages.

TAX1BP1 and FIP200 orchestrate non-canonical autophagy of p62 aggregates for mouse neural stem cell maintenance

Autophagy plays a pivotal role in diverse biological processes,including the maintenance and differentiation of neural stem cells(NSCs).Interestingly,while complete deletion of Fip200 severely impairs NSC maintenance and differentiation,inhibiting canonical autophagy via deletion of core genes,such as Atg5,Atg16l1,and Atg7,or blockade of canonical interactions between FIP200 and ATG13(designated as FIP200-4A mutant or FIP200 KI)does not produce comparable detrimental effects.This highlights the likely critical involvement of the non-canonical functions of FIP200,the mechanisms of which have remained elusive.Here,utilizing genetic mouse models,we demonstrated that FIP200 mediates non-canonical autophagic degradation of p62/sequestome1,primarily via TAX1BP1 in NSCs.Conditional deletion of Tax1bp1 in fip200hGFAP conditional knock-in(cKI)mice led to NSC deficiency,resembling the fip200hGFAP conditional knockout(cKO)mouse phenotype.Notably,reintroducing wild-type TAX1BP1 not only restored the maintenance of NSCs derived from tax1bp1-knockout fip200hGFAP cKI mice but also led to a marked reduction in p62 aggregate accumulation.Conversely,a TAX1BP1 mutant incapable of binding to FIP200 or NBR1/p62 failed to achieve this restoration.Furthermore,conditional deletion of Tax1bp1 in fip200hGFAP cKO mice exacerbated NSC deficiency and p62 aggregate accumulation compared to fip200hGFAP cKO mice.Collectively,these findings illustrate the essential role of the FIP200-TAX1BP1 axis in mediating the non-canonical autophagic degradation of p62 aggregates towards NSC maintenance and function,presenting novel therapeutic targets for neurodegenerative diseases.
