实行档案提供利用方式的多样化,对档案利用率能够产生显性、半显性和隐性的作用。现有的档案利用率计算公式已不能适应这种多样化的要求,需要进行合理调整。 相似文献

创新是企业内涵式的增长方式,并购是企业外延式的增长方式。在资源有限的情况下,企业如何在这两种战略之间进行权衡?本文以2007-2018年沪深A股上市公司为研究样本,发现如果并购引起企业资产负债率增加,则会对并购后的R&D投资形成"财务侵占",从而对研发产生负面影响;这种抑制作用在主并企业存在融资约束的情况下会更加显著;按企业特征划分,这种抑制作用主要存在于小企业和民营企业。研究结果为基于边界条件的并购如何影响企业创新绩效提供了实证证据,同时也为企业进行相关战略变更和投资决策提供了有益参考。 相似文献

This article presents the Kaleckian model of growth and distribution that sets a budget deficit ratio as an indicator of fiscal policy and examines the short- and long-run effects of an increase in budget deficits and a rise in income tax rates on the economy. The key short-run outcomes are as follows. First, expanded budget deficits have a positive effect on the rate of capacity utilization. Second, the tax rate for wage income does not affect the rate of capacity utilization, whereas the tax rate for capital income has a favorable impact on it. This result implies that raising the tax rate for capital income can be an important policy instrument for stimulating the economy. Third, we find that the economy exhibits a wage-led aggregate demand in the short run. The main long-run results are as follows. First, the effect of expanded budget deficits on the growth rate is ambiguous, since a higher debt burden negatively influences the rate of capacity utilization and hence economic growth, despite the increase in demand caused by government borrowing. A higher budget deficit ratio thus raises the growth rate only if a certain condition is satisfied. Second, the tax rate for capital income has a positive impact on the growth rate. Third, the economy shows a wage-led growth in the long run. 相似文献

Warren Buffett suggested that the ratio of the market value of all publicly traded stocks to the Gross National Product could identify potential overvaluations and undervaluations in the US equity market when this ratio deviates above 120% or below 80%. We investigate whether this ratio is a statistically significant predictor of equity market corrections and rallies. We find that Buffett's decision rule does not deliver satisfactory forecasts. However, when we adopt a time-varying decision rule, the ratio becomes a statistically significant predictor of equity market corrections. The two time-varying decision rules are: (i) predict an equity market correction when the ratio exceeds a 95% one-tail confidence interval based on a normal distribution, and (ii) predict an equity market correction when the ratio exceeds a threshold computed using Cantelli's inequality. These new decision rules are robust to changes in the two key parameters: the confidence level and the forecasting horizon. This paper also shows that the MV/GNP ratio performs relatively well against the four most popular equity market correction models, but the ratio is not a particularly useful predictor of equity market rallies. 相似文献

Using hand‐collected data, we creatively construct an ‘on‐balance‐sheet shadow banking business’ (OBS‐SBB) measure to precisely quantify commercial banks’ shadow banking activity concealed on their balance sheets. We show that OBS‐SBB activities could both increase individual and systemic risks. To further test the underlying mechanisms, we use China’s implementation of Basel III as an exogenous shock and employ the difference‐in‐differences approach. We find that banks demand OBS‐SBB in order to bypass capital requirements, previously less‐capitalised banks significantly increase their OBS‐SBB ex‐post, and greater impact is found among small and medium‐sized banks and during loose monetary policy periods. 相似文献

Financial inclusion is emerging as a new paradigm of economic growth that plays major role in driving away the poverty from the country. It refers to delivery of banking services to masses including privileged and disadvantaged people at an affordable terms and conditions. Financial inclusion is important priority of the country in terms of economic growth and advanceness of society. It enables to reduce the gap between rich and poor population. In the current scenario financial institutions are the robust pillars of progress, economic growth and development of the economy. The present study aims to examine the impact of financial inclusion on growth of the economy over a period of seven years. Secondary data is used which has been analyzed by multiple regression model as a main statistical tool. Results of the study found positive and significant impact of number of bank branch and Credit deposit ratio on GDP of the country, whereas an insignificant impact has been observed in case of ATMs growth on Indian GDP. 相似文献

Does the bond‐stock earnings yield differential model predict equity market corrections better than high P/E models? 下载免费PDF全文
We extend the literature on crash prediction models in three main ways. First, we explicitly relate crash prediction measures and asset pricing models. Second, we present a statistical significance test for crash prediction models. Finally, we propose a definition and a measure of robustness for these models. We apply our statistical test and measure the robustness of selected model specifications of the Price‐Earnings (P/E) ratio and Bond Stock Earning Yield Differential (BSEYD) measures. This analysis shows that the BSEYD and P/E ratios, were statistically significant robust predictors of corrections on the US equity market over the period 1964 to 2014. 相似文献

Motivated by the recent phenomenal growth in Islamic finance and the financialization of commodities, this study makes an initial attempt to investigate the risk–return profiles of optimized portfolios combining (a) Islamic equities with commodities and (b) conventional equities with commodities during the crises and noncrises periods. The findings tend to indicate that Islamic equity–commodity portfolios provide relatively higher diversification benefits than the conventional equity–commodity portfolios during the 1997 Asian Financial Crisis triggered by the financial sector compared to the 2008 global financial crisis triggered by the real housing sector. The findings further suggest that except for a few cases, commodities in general and gold in particular improve diversification benefits. 相似文献

中国全过程减排效应实证研究——以省域二氧化硫减排为例 总被引:1,自引:0,他引:1
全过程污染减排,是以经济发展模式转变为前提,构建从资源能源消费,污染物产生以及到污染排放的全过程减排机制.文章以省城二氧化硫减排为例,根据全过程减排内涵,选择减排率作为全过程减排评价指标,选择节能降耗、技术进步、产业结构、治污、监管激励等环节指标,对中国全过程减排效应进行实证分析.结果表明,全过程污染减排已在中国存在一定程度的效应.作为“中端”减排的三产比重效应较小,而技术进步效应更小,这应该是今后减排工作的重点.由此提出相应的政策建议. 相似文献
