In the context of personal income tax (PIT) reform in China in 2018, this paper examines some of the major issues of concern regarding the reform and income distribution. Using the China Personal Income Tax Micro‐simulation model, the paper compares the differences between the 2011 and 2018 PIT systems, and finds that residents relying on different income sources may face a large degree of real tax rate change. Once the tax system is altered to PIT 2018, the coverage of PIT for wage earners will decrease from 46.9 to 23.4 percent, the income redistributive effect will drop from 1.95 to 1.22 percent and the PIT's role in fiscal revenue will also be negatively affected. Nevertheless, if individual income continues to grow, the share of PIT in fiscal revenue is expected to return to the 2018 level in 2022, but its income redistribution function is difficult to recover in the short term. The paper finds that the effect of PIT on income distribution depends on the tax structure. Gradual transition to an “entirely comprehensive” tax system when conditions are appropriate will achieve better income redistribution results at a lower average tax rate. 相似文献

Most studies on the predictability of moving average (MA) technical analysis use the discrete (buy/sell) trading recommendations. However, it is possibly incomplete or unreliable to explore the predictability of MA by only employing its generated trading signals. To further explore the forecastability of MA, we study its measurable impact on the stock market returns by using a conventional predictive regression framework. Our empirical study on the US stock market with respect to more detailed price information finds, (i) that the proposed predictor, MADP (MA based on daily prices) shows significant predictability in‐ and out‐of‐sample, and significantly outperforms the historical average (HA) benchmark as well as the MA based on monthly prices, (ii) that the predictability of MADP centers on the short‐term lags (within the most recent 10 days) and disappears when lags are beyond 20 days, and (iii) that the economic evaluation of the portfolios based on trading strategies confirms the superior performance of MADP with short‐term lags against the benchmark even though considering transaction costs. 相似文献

旅游收入是旅游经济活动的重要内容,它一方面反映了旅游者的旅游需求通过旅游经营者的旅游供给而不断得到满足,另一方面又体现着旅游产业部门和企业在产经营活动的价值运行与价值实现。旅游收入与分配是旅游经济运行的前提,对其进行考察分析,是十分重要的。本章从收入和分配两个方面入手,对旅游收入分类、指标、旅游企业收入和分配以及旅游收入乘数的作用等进行了分析和阐述。 相似文献

Theory suggests that a close match between revenue and expenditure assignments at sub-national levels benefits allocative efficiency, and hence economic growth. That is, a convergence of revenue and expenditure assignments at sub-national levels of government should, according to the theory, be positively associated with a higher growth rate. In the case of China, this paper shows, divergence, rather than convergence, in revenue and expenditures at the sub-national level of government is associated with higher rates of growth. A panel dataset for 30 provinces in China is used to examine the relationship between fiscal decentralization and economic growth over two phases of fiscal decentralization in China: (1) 1979–1993 under the fiscal contract system, and (2) 1994–1999 under the tax assignment system. The seeming contradiction between the theory and evidence in the China case is reconciled by taking into account the institutional arrangements that prevailed during the two phases of fiscal decentralization, in particular the inconsistency between the assumptions of the theory of fiscal decentralization and the institutional reality of China. 相似文献

一个国家或地区的经济开放程度涉及很多方面,如贸易国际化、资本国际化、劳动力跨国流动、技术引进和输出等。基于操作上简便易行、指标上具有可比性和连续性、资料易于搜集和量化等原则,本文拟选择出口额、实际利用外商直接投资额与GDP建立对外开放度这一指标。通常情况下,有些学者还会考虑国际投资开放度这个指标,但是.在计划计算苏南、苏中及苏北的国际投资开放度这一指标时发现:一方面由于统计资料的限制.另一方面由于苏南、苏中及苏北的对外投资数额很小, 相似文献

我国救济性投资的救济力度远远低于救济需求,在社会救济意识、救济管理、资金来源、投资形式等方面存在不足,投资增长缓慢,且存在城乡失衡和地区失衡.应创新公民的社会保障观念和思维模式,建立健全救济性投资的管理机制,着力解决救济性投资的不平衡问题,并且投资形式要向着多元化、多层次的方向发展. 相似文献
