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

Summary Consider the problem of finding an estimator for a scale parameter such that its risk function is bounded by a preassigned
constant. As a solution of the problem, two-stage estimators based on only the second sample have been proposed. The paper
shows that these estimators can be improved by combining the first and the second sample. 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 This paper constructs and studies a simple but realistic model of an insurance market. The model has a minimalist construction in the sense that the number of parameters defining it is strictly limited and the elimination of any one of them would destroy its realism. There are 11 essential parameters. Each of the parameters has a physical interpretation. Some determine competitive effects within the market, some barriers to entry, and so on. The effect of each on various aspects of the market is examined in the presence of simulated loss experience. The aspects of the market considered include stability of premium rates, profitability, and market concentration. Some of the parameters are capable of use as regulatory controls. Two parameters, in addition to the original 11, are explicit price controls. Despite its simplicity, the model displays considerably complex behavior. Some results are intuitive, but some are not. For this reason, regulatory controls need to be applied with great caution lest they induce perverse effects, possibly even the reverse of those intended. The effect of the parameters on market behavior is first studied in the absence of catastrophic events from the loss experience. Subsequently, the effect of a single such event is studied. 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 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

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

Abstract In this article, we propose a finite-state Markov process with one absorbing state to model human mortality. A health index called physiological age is introduced and modeled by the Markov process. Under this model the time of death follows a phase-type distribution. The model possesses many desirable analytical properties useful for mortality analysis. Closed-form expressions are available for many quantities of interest including the conditional survival probabilities of the time of death and the actuarial present values of the whole life insurance and annuity. The heterogeneity or frailty effect of a cohort can be expressed explicitly. The model is also able to explain some stylized facts of observed mortality data. We fit the model to some Swedish population cohort data and life tables compiled by the U.S. Social Security Administration. The fitting results are very satisfactory. 相似文献
