国家明确以税收优惠的形式鼓励和引导企业和个人参加企业年金计划,并于2014年实施了个税递延政策。基于指标模型构建和数据模拟,本文对我国企业年金在个税递延政策实施前后的保障水平进行了比较,通过参数敏感性分析考察了投资收益、工资增长、退休年龄和缴费比例等因素的影响。研究发现,实施个税递延政策后企业职工的养老保障水平在较大程度上低于政策实施前,但不同性别、不同收入水平和不同缴费比例的企业职工保障水平降低的程度有所差异。收入水平和缴费比例越高的男性职工,个税递延政策实施后保障水平降低的幅度越高,但对女性职工而言,这种影响要弱一些。进一步,可以通过增加投资收益、延迟退休年龄和提升缴费比例等方法来提高企业职工的养老保障水平,这与目前正在进行的一系列改革方向也一致。  相似文献

Although Chinese banks are the major creditors for companies in China, their role in bankruptcy is often neglected. Even if this may be justified in the past, as banks did not assume an important role, it is not the case now as banks have become more proactive in the bankruptcy procedure and begin to conduct debt‐for‐equity swaps under the initiative of the government. This article considers the role of Chinese banks in bankruptcy both in and out of formal bankruptcy procedure. It argues that based on the reality of the country, especially its corporate governance structure, bank intervention is feasible for corporate rescues in China. The debt‐for‐equity swap scheme could be the start. Copyright © 2018 INSOL International and John Wiley & Sons, Ltd.  相似文献

Given the constraints on carbon emissions due to their impact on global warming, carbon disclosure has become an important way to deliver signals to the market. We examine the benefits associated with carbon disclosure from the standpoint of corporate social responsibility (CSR) for China’s manufacturing industries from 2010 to 2014. We divide corporations into heavily polluting and non-heavily polluting groups in order to control the industry factor. Based on the Principal-Agent Theory, we empirically test the relationship between carbon disclosure and financial transparency, and we evaluate the effect of carbon disclosure on agency costs and operations. Our results highlight that carbon disclosure is negatively associated with agency costs. However, we do not find enough evidence to prove what role financial transparency plays in the relationship between carbon disclosure and agency cost. Therefore, the influence of financial transparency as a mechanism is not yet clear. This study provides a way to look at the intentions of firms that disclose carbon information, and it also enhances the literature on carbon disclosure and agency costs in China based on Chinese data.  相似文献

This paper aims to build a theoretical framework for the influence of risk awareness of interpersonal trust (RAIT) on entrepreneurship, and explores the influence of RAIT on entrepreneurship with the micro survey data from the Chinese General Social Survey (CGSS) 2010–2013. The study found that, individuals with higher level of RAIT, their probability of starting new business will increase significantly, and with every increase of RAIT level, the probability of business venturing increase almost 4.0%. No mediation effects of information screening and cooperative mechanism are found in the relationship between RAIT and entrepreneurship. Moreover, during the venturing process, risks accompanying interpersonal trust cannot be reduced by social input; the reduction occurs only in eastern China where the economic system and the industrial development standards are more comprehensive and mature. This paper contributes to the literatures in the following two areas: it provides new evidence on how to deal with risks in the entrepreneurship process that accompanying interpersonal trust; meanwhile, it provides an explanatory mechanism on how the risk awareness affects business venturing.  相似文献

This article investigates the nexus between insurance and economic growth in China with a dynamic interactive mechanism to study different time periods. Using quarterly data from 1999 to 2015, the rolling-window causality test provides evidence of bidirectional causality between insurance activity and economic growth. However, the “supply-leading” pattern tends to dominate the “demand-following” pattern, which implies that in China insurance acts as a stimulus of economic growth during most of the period. Property insurance is more effective than life insurance in stimulating economic growth. Some temporary negative impacts from the development of the insurance sector show that China is in the midst of a transition from a closed economy to a more open economy and policy interventions by the government to liberalize the insurance sector. These findings offer several useful insights for policy makers in transition economies and developing countries.  相似文献

Annual reports are the main sources of information for outside investors’ investment decisions and enable shareholders to supervise the management. Difficulties with the readability of these reports may therefore have serious consequences. Using 19,221 firm-year observations of Chinese A-share listed firms from 2001 to 2015, we investigate the association between annual report readability and corporate agency costs, where readability is proxied by report file length and/or file size. We find that firms with better annual report readability experience lower agency costs, and the negative association between readability and agency costs is more pronounced in firms with higher external audit quality, internal control quality or analyst coverage. These results hold after several robustness checks. The positive effect of annual report readability is stronger in private firms than in state-owned enterprises, and becomes stronger after the implementation of new accounting standards in 2007. Readable annual reports can help in monitoring corporate insiders’ opportunistic behavior and thus reduce agency costs.  相似文献

本文采用时间序列数据对财政支农支出与农民收入之间的关系进行了实证研究。 结果显示财政支农资金对农村居民收入产生了显著的正面影响;财政支农结构中,支援农业生 产支出对农民收入的影响最大,然后依次是农业基本建设支出和农村救济费,而农业科技三项 费用对农民收入的影响不显著。综合考虑财政对三农、教育、健康的投入的研究结果显示,国 家在健康方面的投入对农村居民纯收入的正面影响最大,其次是对“三农”的支出,农村居民 的受教育水平对农村居民的纯收入的影响为负,但对农村居民的经营性纯收入和工资性纯收入 的影响为正。在此基础上,结合国家精准扶贫背景,本文建议应继续加大财政对“三农”的支 持力度,同时重视对农村健康和教育方面的投资,在健康与教育之间,应该优先选择提升农村 居民的健康水平。  相似文献

货币政策由数量型向价格型调控转型过程中,价格似乎变得更为重要。尽管如此, 货币数量与资金价格仍是观察“硬币”的两面,数量的趋势或能预判价格的变化。金融严监管 的背景下,货币数量尤其是广义M2在过去一年出现剧烈的收缩,而另一个货币数量指标社会 融资规模却仍然强劲,二者的分化使得我们感知货币松紧以及经济冷暖出现分歧。本文基于 M2和社会融资组成结构的异同点,分别对M2和社会融资近年来在金融自由化和金融监管收紧 过程中的变化机理进行梳理,并对未来趋势予以预判。首先,文章区分了M2和社会融资的组 成结构异同点,从共同的影响因素信贷入手进行分析和预判;其次,依据货币派生的机理,从 商业银行资产负债表来分析引起M2变动的主要矛盾进行深入解读;再次,对于引发社会融资 变动的信托和委托变化趋势予以分析。最后我们得出结论,由于监管重点的时间差异使得此轮 M2先于社会融资回落,未来二者分化将逐步收敛。  相似文献

We study a credit term determination problem in the context of a supplier-buyer supply chain. The supplier's credit term decision is simultaneously made with its production and inventory decisions, and most importantly, it is impacted by the buyer's order quantity. We present a new game-theoretic framework to model this problem, which captures the interaction between the supplier's credit term decision and the buyer's order decision in a multi-period setting. An exact method based on nonlinear programming is implemented to obtain the optimal solutions. We apply our methodologies on a real world case. The computational results show that our approach significantly outperforms the heuristics with fixed credit terms, and either a short or a long credit term can be sub-optimal for the supplier in profitability. Our work offers the first data-driven model and solution approach that assists purchasing and supply managers to make optimal dynamic credit term decision in conjunction with production, ordering and inventory decisions in a game-theoretic setting.  相似文献
