摘 要:21世纪以来,中国制造业企业进行房地产投资是其“多元化”投资战略的主 要形式之一。本文利用2010-2020年中国 A 股上市制造业企业数据,研究了制造业企业 房地产投资对企业杠杆率的影响,发现制造业企业房地产投资能够提升企业杠杆率。机 制分析表明,制造业企业房地产投资通过发挥挤压效应和抵押效应进而提高企业杠杆率。 制造业企业房地产投资对企业杠杆率的提升作用在非国有企业和小企业中更显著。在区 分长期杠杆率和短期杠杆率后,制造业企业房地产投资对企业杠杆率的提升作用表现在 长期杠杆率方面,同时该提升作用显著提高了企业的财务风险。本文提出企业应当加大 研发创新,促进自身高质量发展;政府监管部门完善系列政策避免制造业企业盲目进行房地产投资而导致“企业空心化”。  相似文献

The behavior and spatial distribution of crime events can be explained through the characterization of an area in terms of its demography, socioeconomy, and built environment. In particular, recent studies on the incidence of crime in a city have focused on the identification of features of the built environment (specific places or facilities) that may increase crime risk within a certain radius. However, it is hard to identify environmental characteristics that consistently explain crime occurrence across cities and crime types. This article focuses on the assessment of the effect that certain types of places have on the incidence of property crime, robbery, and vandalism in three cities of the Valencian region (Spain): Alicante, Castellon, and Valencia. A nonlinear effects model is used to identify such places and to construct a risk map over the three cities considering the three crime types under research. The results obtained suggest that there are remarkable differences across cities and crime types in terms of the types of places associated with crime outcomes. The identification of high-risk areas allows verifying that crime is highly concentrated, and also that there is a high level of spatial overlap between the high-risk areas corresponding to different crime types.  相似文献

瞪羚企业认定是我国创新驱动发展战略的重要措施,旨在培育高科技、高成长性企业,促进科技进步和经济高质量发展。为研究瞪羚企业认定能否切实提升企业创新质量,利用2005-2018年新三板企业数据和PSM-DID方法研究瞪羚企业认定对企业创新质量的影响及作用机制。结果发现:①瞪羚企业认定对企业创新质量有正向促进效应,且这种效应在地区和企业层面均存在异质性;②人力投入是瞪羚企业认定发挥作用的重要渠道;③制度因素对瞪羚企业认定影响的调节效应有限,意味着我国市场化改革和知识产权保护工作仍需进一步完善。最后,为政府有效开展瞪羚企业认定工作、促进企业提高创新质量提出政策建议。  相似文献

We analyze the institutional determinants of U.S. financial market regulation with a general model of the policy-making process in which legislators delegate authority to regulate financial risk at both the firm and systemic levels. The model explains changes in U.S. financial regulation leading up to the financial crisis. We test the predictions of the general model with a novel, comprehensive data set of financial regulatory laws enacted specifically between 1950 and 2009. The theoretical and empirical analysis finds that economic and political factors impact Congress’ decision to delegate regulatory authority to executive agencies, which in turn impacts the stringency of financial market regulation, and our estimation results indicate that political factors may have been stronger and resulted in inefficiencies.  相似文献

代际传承背景下家族企业创新投入是家族企业治理研究领域的重要问题。分析和检验了差异化二代继任方式如何影响家族企业创新投资水平,以及二者关系是否会依赖于家族权威差异而发生变化。研究结果发现:与渐进型二代继任相比,激进型二代继任会削减家族企业创新投入;二代继任方式与家族企业创新投入关系受到家族权威的影响。在家族成员权威和非家族创业元老权威较重的企业,激进型继任者对家族企业创新投入的削弱效应更显著。进一步研究发现,二代继任3年后,激进型继任者对家族企业创新投入的负面影响显著下降,且其削弱效应在规模较大企业以及创立时间较长的企业中更显著。  相似文献

待孵化的技术创业型企业同时具有概念性技术向差异化产品转化的高风险与产品异质性被认同后溢价评估的高收益特点,导致其投资者多处于隔岸观火却欲罢不能的的孵化投资矛盾中。对孵化资本实施有效的风险管控,成为吸引外部资本投入的关键。基于此,选择在可创概念选育与技术创业孵化领域探索出高成功率路径的概念证明中心、YCombinator和创新工场为研究案例,分析其在创业项目筛选、孵化资金运营等关键环节的风险管控方式,以期完善我国孵化资本管控理论、助力我国商业孵化器提高资金风险管控能力、促进外部资本投入。  相似文献

We suggest that the distortion of the positive risk–return relation in the ICAPM is a consequence of trading by informed investors to exploit mispricing. We hypothesize and demonstrate that a non-positive (strongly positive) risk–return relation following positive (negative) market returns is attributed to short-selling (purchasing) of overpriced (underpriced) stocks along with optimistic (pessimistic) expectations conditional on good (bad) market news. We verify this asymmetry in the risk–return relation through the indirect risk–return relation conditional on good (bad) market news. We also find that the attenuation (reinforcement) of the positive risk–return relation is more profound in high- (low-) sentiment periods.  相似文献

This study investigates whether gold, USD, and Bitcoin are hedge and safe haven assets against stock and if they are useful in diversifying downside risk for international stock markets. We propose a combined GO-GARCH-EVT-copula approach to examine the hedge and safe haven properties of gold, USD, and Bitcoin. We then examine the attractiveness of these assets in reducing stock portfolio risk by using downside risk measures estimated by the proposed approach and other competing models. We also evaluate the relative performance of the proposed model in reducing downside risk with the competing models. The findings of the study indicate that the USD is the most valuable hedge and safe haven asset closely followed by gold, while Bitcoin is the least valuable. It is also observed that the proposed combined approach performs best in reducing the portfolio downside risk. The findings of this study are of significance for portfolio managers and individual investors who wish to protect the portfolio value during market turmoil.  相似文献

Using data on Brazil, Colombia, Mexico, the Philippines, Russia and Turkey, our empirical results show that the exchange rates of their currencies have adequate explanatory power in explaining their US dollar-denominated sovereign bonds, particularly in the post-global financial crisis period. We develop a two-factor pricing model with closed-form solutions for the sovereign bonds in which the correlated factors are foreign exchange rates and US risk-free interest rates that follow a double square-root process relevant in the low interest rate environment. The numerical results and associated error analysis show that the model credit spreads can broadly track the market credit spreads.  相似文献

道德风险总是困扰着职业经理人群体,对企业发展产生不利影响。在实践中,作为建立健全社会信用体系的重要环节,职业经理人信用评价是防范职业经理人群体道德风险的基本思路和必要举措。本文基于马克思主义的理论启示,探索职业经理人三个维度的道德关系和道德风险,并围绕三个维度指向的个人信用、职业信用与职务信用等具体信用构成,阐述职业经理人信用评价内涵。进而,结合职业经理人信用评价内涵,构建系统应对道德风险的职业经理人信用评价体系,并以重庆为例进行实证测度。在此基础上,提出促进职业经理人道德意识与信用水平提升、实现新时代职业经理人群体高素质发展的对策建议。  相似文献
