Against the background of supply-side structural reform and the real estate financialisation in China, this study investigates the impact of real estate holdings on R&D investment using data of enterprises listed on the Shanghai and Shenzhen stock exchanges. Our empirical results yield five main findings. First, enterprises holding more real estate assets face more serious financial constraints, thus restraining corporate innovation efficiency. Second, when the profit margin gap between entity enterprises and the real estate industry is larger, enterprises are more inclined to transfer industrial capital into the real estate industry, thus reducing R&D investment. Third, when the degree of marketisation is high, intensified market competition, the optimal allocation of factor and product markets, and stronger patent protection will weaken the restraining effect of corporate real estate holdings on R&D investment. Fourth, monopoly enterprises obtain potential profits more than undertaking risks from the real estate industry, they are more willing to hold real estate, thus strengthening the restraining effect of real estate holdings on innovation. Finally, investors' regional preference intensifies the restraining effect of corporate real estate holdings on R&D investment. Our empirical evidence can guide entity enterprises on how to effectively balance short-term (non-productive) and long-term (productive) capital investment.  相似文献

Globally, society has been facing several and growing health problems, which increased the importance of efforts towards social change. In this context, using social marketing to create and implement programs that foster behavioural change has increased in the public health community. One of the health problems that society has been facing is the unceasing need for blood products, so the subject of blood donation became an important research topic in the area of social marketing, as social marketing strategies can contribute to solving this problem. It is essential to understand the factors that motivate individuals to donate blood, to enhance the recruitment and retention of blood donors. Our study aims at evaluating the key personality factors that influence blood donation behaviour to reach a higher understanding of what concerns this global issue. The method used to analyse the data is ANOVA. We conclude that the Personality of potential donors is significantly different from the non-donors' regarding Openness to Experience and Agreeableness. These results suggest that potential donors might perceive blood donation, as well as the associated barriers, differently from non-donors. Based on our findings, we suggest some perspectives for future research in this area.  相似文献

防御性现实主义:进攻性现实主义时代的悲剧   总被引:1,自引:0,他引:1  
作者旨在回答一个重要的问题:防御性现实主义在进攻性现实主义时代的命运如何?这个问题可以分解为两个小问题:进攻性现实主义时代下的防御性现实主义国家面临哪些生存压力?这些生存压力对防御性现实主义国家会造成哪些影响?作者认为,在进攻性现实主义时代,防御性现实主义国家面临五种生存压力:防御性现实主义国家是进攻性现实主义国家进攻的诱因;防御性现实主义国家经常遭遇进攻性现实主义国家的攻击;防御性现实主义国家被进攻性现实主义国家包围;防御性现实主义国家几乎无法和进攻性现实主义国家合作;防御性现实主义国家的军力通常在整体上或在关键指标上落后于进攻性现实主义国家。在这些生存压力之下,防御性现实主义国家的生存质量堪忧,在重要的物质利益和国家的自主性两项指标上的表现难如人意。作者采取了案例分析的方法,以中国宋朝和波兰为例,论证了进攻性现实主义时代的防御性现实主义困境。  相似文献

亚洲工厂及关联度分析   总被引:1,自引:0,他引:1  
依据亚洲零部件贸易数据,作者采用了依存比率的方法对亚洲工厂的规模、工厂内部以及同美国之间的相互依存关系进行了研究。研究结果发现,亚洲工厂的规模超过北美洲和欧洲工厂,成为了世界上最大的工厂。亚洲零部件内部贸易额及比重超过了欧盟,这说明亚洲生产的一体化程度更高。从零部件进出口规模角度看,亚洲地区的经济体均高度依赖亚洲工厂的活动,而亚洲工厂对中国的依存度则最高,对日本的依赖程度只排在第三位,这说明中国是亚洲工厂的核心平台。美国在亚洲贸易中的重要性主要体现为中国的最终产品出口对美国市场存在严重依赖,而亚洲主要经济体对中国市场的出口已经超过对美国的出口,亚洲工厂对于美国的依赖程度并不高,远远低于亚洲工厂对中国内地和中国香港的依赖。相反,美国对亚洲工厂的依赖程度则远高于亚洲工厂对美国的依赖。  相似文献

The rapid and sustained growth of several Asian economies led researchers, policymakers, and decision‐makers in the world of international business to search for a plausible Asian model of growth. Numerous explanations of the dynamic growth in Asia have been put forward, including the ‘new structuralist’ approach proposed by Lin (2012). This paper examines the various explanations of what these countries did to unleash their growth potential. Industrial policy and market intervention are two such explanations. While the dynamic Asian economies did not flout the Washington Consensus, they adapted it in different ways. The policies that they followed under the Beijing Consensus allowed them to proactively follow pro‐business policies. They also exploited the concepts of economic statism or state capitalism, which became an integral part of what became known as the ‘Asia model’.  相似文献

Abstract

This study investigates the risk inherent in defined contribution (DC) pension plans on an individual and aggregate basis, based on U.S. data. Our aim is to gain insight into the consequences of a DC pension scheme becoming the predominant pillar of retirement income for an entire society. Using the stochastic simulated output of a DC flexible age-of-retirement model, we first determine the optimal investment strategies. We then examine the demographic retirement dynamics of an entire population of DC pension plan participants.

We observe that even for the most risk-averse plan members there is a high level of uncertainty in an individual’s age at retirement. At the aggregate population level, we find that this uncertainty does not get dampened to any great extent by a diversification effect. Instead, the central role played by the market in determining retirement dates results in significant variation in the dependency ratio (the ratio of retirees to workers) over time. In addition, an attempt to ameliorate the outcome by introducing additional realistic features in the DC population modeling did little to dampen this volatility, which suggests that countries dominated by DC schemes of this type may, over time, be exposed to significant risk in the size of its labor force.  相似文献

Abstract

In this paper we analyze the risk underlying investment guarantees using 78 different econometric models: GARCH, regime-switching, mixtures, and combinations of these approaches. This extensive set of models is compared with returns observed during the financial crisis in an out-of-sample analysis, bringing a new perspective to the study of equity-linked insurance. We find that despite the very good fit of recent models, too few of them are capable of consistently generating low returns over long periods, which were in fact observed empirically during the financial crisis. Moreover, tail risk measures vary significantly across models, and this emphasizes the importance of model risk. Most insurance companies are now focusing on dynamically hedging their investment guarantees, and so we also investigate the robustness of the Black-Scholes delta hedging strategy. We find that hedging errors can be very large among the top fitting models, implying that model risk must be taken into consideration when hedging investment guarantees.  相似文献

Abstract

We show that the only coherent distortion risk measure that is consistent with respect to 3-convex order and hence with stochastic dominance of order 3 is the expected value, thus generalizing previous results of Hurlimann and solving a problem posed by Yamai and Yoshiba.  相似文献

Abstract

In this article we investigate three related investment-consumption problems for a risk-averse investor: (1) an investment-only problem that involves utility from only terminal wealth, (2) an investment-consumption problem that involves utility from only consumption, and (3) an extended investment-consumption problem that involves utility from both consumption and terminal wealth. Although these problems have been studied quite extensively in continuous-time frameworks, we focus on discrete time. Our contributions are (1) to model these investmentconsumption problems using a discrete model that incorporates the environment risk and mortality risk, in addition to the market risk that is typically considered, and (2) to derive explicit expressions of the optimal investment-consumption strategies to these modeled problems. Furthermore, economic implications of our results are presented. It is reassuring that many of our findings are consistent with the well-known results from the continuous-time models, even though our models have the additional features of modeling the environment uncertainty and the uncertain exit time.  相似文献

Abstract

Consider a portfolio containing number of risk classes. Each class has its own demand function, which determines the number of insureds in this class as a function of the premium. The insurer determines the premiums based on the number of insureds in each class. The “market” reacts by updating the number of the policyholders, then the insurer updates the premium, and so on. We show that this process has an equilibrium point, and then we characterize this point.  相似文献
