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

For a variety of reasons, this article argues, electricity must be seen by policy‐makers in South Africa not as the sole provider of all future household energy needs, but rather as one component of an energy mix which includes such ‘transitional’ fuels as coal, gas and paraffin. The reasons for this are that electricity is expensive for poor households; it is subject to power failures and disconnections for non‐payment; the poor find it difficult to monitor and to control their consumption; appliances are expensive and several are required to make best use of electricity; people prefer other fuels because they are familiar and have strong personal and cultural associations, and because Eskom is not trusted owing to its past ties to illegitimate local authorities and misunderstanding of electricity and how its use is monitored and charged for. Further, it is mistaken to equate ‘development’ with total electrification: most developed countries have fuel mixes which include gas and coal, particularly for cooking and heating. Accepting an affordable fuel mix for the poor in particular would focus attention on the problems currently associated with paraffin, gas and coal, namely fires, poisoning and air pollution. 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

Bentler and Raykov (2000, Journal of Applied Psychology 85: 125–131), and Jöreskog (1999a, http://www.ssicentral.com/lisrel/column3.htm, 1999b http://www.ssicentral. com/lisrel/column5.htm) proposed procedures for calculating R 2 for dependent variables involved in loops or possessing correlated errors. This article demonstrates that Bentler and Raykov’s procedure can not be routinely interpreted as a “proportion” of explained variance, while Jöreskog’s reduced-form calculation is unnecessarily restrictive. The new blocked-error-R 2 (beR 2) uses a minimal hypothetical causal intervention to resolve the variance-partitioning ambiguities created by loops and correlated errors. Hayduk (1996) discussed how stabilising feedback models – models capable of counteracting external perturbations – can result in an acceptable error variance which exceeds the variance of the dependent variable to which that error is attached. For variables included within loops, whether stabilising or not, beR 2 provides the same value as Hayduk’s (1996) loop-adjusted-R 2. For variables not involved in loops and not displaying correlated residuals, beR 2 reports the same value as the traditional regression R 2. Thus, beR 2 provides a conceptualisation of the proportion of explained variance that spans both recursive and nonrecursive structural equation models. A procedure for calculating beR 2 in any SEM program is provided. 相似文献

There is a sizeable group of self-described Christian companies which have declared their belief in the successful merging of biblical principles with business activities. As these companies have become more visible, an increasing number of anecdotal newspaper and magazine articles about these companies have appeared. Surprisingly, no rigorous research has been conducted prior to our recent study. This article provides national estimates of the size and predominant characteristics of self-identified Christian companies. In addition, the study investigated the types of relationships these companies maintained with their employees, customers, communities, and suppliers.Nabil Ibrahim is an Assistant Professor of Business Administration at Augusta College, Augusta, Georgia.

We consider a country with two factors and two industries, each of which faces technical and price uncertainty. Entrepreneurs choose outputs in order to maximize the expected utility of profits. They also draw factor payments and purchase consumption goods after the uncertainty isresolved. They enter and exit from an industry according to whether participation there increases their expected utility. Within this model, the validity of the propositions of neoclassical trade theory depends on how the entrepreneurs' entry decisions are affected by parameter changes via their roles as risk bearers, consumers and factor owners. 相似文献

The solutions that Jane Jacobs proposed to improve neighborhoods created a paradoxical problem: improvement increased demand for the amenities of the area, which caused land prices to rise. The net result was at least partial displacement of the old residents of the neighborhood with new ones. Jane Jacobs has been criticized for ignoring gentrification, but she was clearly aware of this process and tried to find means to counter it. By combining the ideas of Henry George about land taxation with the ideals of Jane Jacobs about neighborhood diversity, we can mitigate the negative effects of gentrification and direct the energy of market forces into producing a greater supply of desirable neighborhoods. 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
