本文通过对全国153个地级及以上城市公租房准入政策和条件进行量化分析,运用主成分分析法构建起公租房准入指数,用以反映城市住房保障水平.以此为基础,本文利用中国家庭金融调查的微观数据,实证检验公租房准入指数对家庭居住公租房的影响.结果 显示,公租房准入指数越高,家庭获得公租房的可能性显著增加,从而验证该指数的合理性.文章发现,尽管在大力倡导新型城镇化的背景下,各地公租房仍然对外市户籍人口存在较高门槛.随着城镇化水平不断提高,人口流动持续增强,中央政府应建立对各城市科学合理的住房保障评估体系,重构地方政府激励机制,提高地方政府住房保障的积极性,同时应加大对外来居民的保障力度.  相似文献

为避免均衡性原则适用的模糊抽象,具体化成为学界共识,量化方法颇受关注。阿列克西设计的“权重公式Wij”的影响力较大,发挥着定序量化分析的功能,但公式的适用范围受限及构成要素的赋值不当,降低了其应用价值。解决问题的关键在于重构“权重公式”的适用框架,法经济学的分析方法能强化公式的适用能力,使量化过程更具客观性。在以利益为核心的成本收益分析框架下,“权利”作为公式的适用对象,经必要变量的逻辑改进,“权利”的保护强度作为公式的构成要素;经济学上的价值及“权利”的损害导向确立公式的量化基础,继而“权利”能实现货币等价或价值评估。尤其基于经济学的替代理论,“权利”之间构成了新的权衡模型:“权衡公式Bij。”在“权衡公式”的结果判定上,Bij≥1,手段不符合均衡性,不应改变“初始状态”下“权利”的比例关系;Bij<1,手段符合均衡性,且尽力选择使Bij值更小之手段。“权衡公式”兼具体系化与精细化分析能力,保持了严密结构和强操作性,为更普遍的实践应用提供新思路。在“权衡公式”与成本收益分析的关系上,它是一种融合成本收益分析的均衡性判断。  相似文献

This research presents a theoretical model and examines it empirically to associate attachment orientations with various types of entrepreneurs. The results show clear evidence that attachment orientations not only predict an adult’s tendency to become an entrepreneur but also the type of entrepreneur he will become. Specifically, the results show that attachment anxiety is the dimension that is the most responsible for the variability of becoming an entrepreneur, while anxiety and avoidant dimensions predict his characteristics and attitudes as an entrepreneur. This paper makes five important contributions to the research of both attachment theory and entrepreneurship. First, it adds to the theoretical understanding of the psychology of entrepreneurs. Second, the attachment theory enables us to extend our understanding beyond the predictions of personality traits regarding entrepreneurial intentions in order to further predict the type of entrepreneur he will turn out to be. Third, it stresses the role of early childhood events regarding the prediction of future entrepreneurial orientation. Fourth, it uses a unique data set of real young entrepreneurs in a single industry homogenous design in Israel, which is known worldwide as a startup nation. Fifth, it focuses on the opportunity validation stage (rather than the opportunity identification of the resource allocation stages), which is often neglected in entrepreneur personality research.  相似文献

Exaggerated portion sizes are generally pictured on the front of product packaging in order to stimulate food craving and encourage consumer purchasing decisions. However, one problem with such images is that they can set inappropriate norms as far as food consumption is concerned and hence result in people serving themselves more than they otherwise might. The research reported here builds on the fact that depicting a food portion in a smaller (vs. larger) container (i.e., plate or bowl) creates the illusion of a larger (vs. smaller) portion, although the actual quantity of food remains the same (this is known as the Delboeuf illusion). Here, we demonstrate in two experiments that by presenting food in a smaller container (thus giving rise to the illusion of a relatively larger portion), participants have higher purchase intentions (study 1) and perceive the food as being more appetizing (study 2) but, crucially, decrease the size of the portion that they serve themselves (studies 1 and 2). Overall, by giving the impression of a larger portion on product packaging, the Delboeuf illusion could potentially be used to nudge consumers to find food more desirable, while at the same time leading them to reduce their serving, thus potentially benefitting both consumers and the food industry.  相似文献

Drawing upon the theory of virtue ethics, this study builds a decision tree predictive model to explore the anticipated impact of good traits (i.e., virtuous and personality traits) on socially responsible consumption. Using R statistical software, we generate a classification tree and cross-validate the model on two independent datasets. The results indicate that the virtuous traits of self-efficacy, courage, and self-control, as well as the personality traits of openness and conscientiousness, predict socially responsible purchase and disposal behavior. Remarkably, the largest segment of socially responsible consumers in the study (41 %) scored high in self-efficacy and openness. This result suggests that marketers should focus on these good traits when creating advertisements to encourage sustainable consumption. Our study contributes to enhancing knowledge about the social and psychological aspects of the sustainability movement and provides a new analytical approach to predicting socially responsible consumption.  相似文献

This paper investigates how the timing of social support, both emotional and instrumental support, affects entrepreneurial persistence of nascent entrepreneurs. Drawing on social support theory, we hypothesize that the effectiveness of support depends on when, during the venture development process (number of gestation activities completed), it is provided. We also propose that the impact of social support depends on when during the entrepreneur’s life stage (age) that support is made available. Testing our hypotheses using a longitudinal dataset of nascent entrepreneurs, we find that emotional support is most relevant earlier on during venture development, while instrumental support is most relevant for entrepreneurs who begin their businesses in earlier life stages.  相似文献

One common justification for the pursuit of profit by business firms within a market economy is that profit is not an end in itself but a means to more efficiently produce and allocate resources. Profit, in short, is a mechanism that serves the market’s purpose of producing Pareto superior outcomes for society. This discussion examines whether such a justification, if correct, requires business managers to remain attentive to how their firm’s operation impacts the market’s purpose. In particular, it is argued that the value of efficiency, despite views to the contrary, cannot be fully separated from the planning and intentions of business managers as long as those managers direct their firms in an ethically responsible fashion. This position is inspired by, and serves as a supportive clarification of Joseph Heath’s so-called “market failures approach” to business ethics.  相似文献

Professionals are knowledge experts who create customized solutions for clients. Many professionals practice in the context of strong professional institutions that prescribe intense socialization and codes and norms. While some professionals work as employees, many start their own firms in order to practice. Firm start-up for professionals is more prevalent than for most other occupations. While professional institutions often constraint their activities, firm start-up for professional service entrepreneurs (PSEs) involves similar entrepreneurial activities as other entrepreneurs, creating an interesting paradox worth investigating. This paper explores the uniqueness of PSEs and the firms they start, and the distinctiveness and value of research in the context of PSEs and professional service firms.  相似文献

保定市主要作物需水量和缺水量特征分析   总被引:1,自引:0,他引:1  
[目的]对作物需水量及缺水量的研究是了解和合理配置农业灌溉用水的基础,对提高农业用水效率有重大意义。[方法]选取河北省保定市为研究区域,利用Penman-Monteith公式和分段单值平均作物系数法对冬小麦、夏玉米和棉花的作物需水量和缺水量等指标进行计算,通过Mann-Kendall检验法对保定市近60年来的作物需水量和缺水量等的变化趋势进行分析。[结果]3种主要作物的需水量、有效降雨量和缺水量的最大值均出现在作物发育中期;其中除冬小麦的有效降雨量以0.208mm/10年的速率呈不显著性增长趋势外,其他作物的各指标变化则均呈减少趋势;从突变现象来看,夏玉米和棉花的各指标发生明显变化的时期相近,需水量出现明显拐点的时刻在2008年以后,有效降水量在1968年以前和2014年两个时期,缺水量分别在2011年和2012年。[结论]该研究结果为保定市乃至河北省的农作物灌溉效率的提高及水资源规划与管理的完善提供了理论依据,具有一定的现实意义。  相似文献

The behavioral approach of decision making has emerged as a diversified solution in the presence of risk and uncertainty. Using the popular cumulative prospect theory as an objective function for portfolio selection, this study implements the classical mean–variance model to compare the portfolio performance of high behavioral stocks with that of stocks with lower behavioral values. Based on a sample of 37 international stocks over the period from October 1998 to November 2017, empirical results from D-vine pair copula GARCH-GEV indicate that the portfolio of high behavioral prospect stocks outperforms the portfolio of stocks with low behavioral scores. This finding may suggest that portfolios with high behavioral values coincide with rational efficiency sets.  相似文献
