This article offers a bottom‐up contribution to the fixity–motion literature. It aims to unravel the apparent contradiction of real estate spatial fixity in Spain, which is portrayed both as a barrier to accumulation and as a unique source of investment by different capitalist actors. Empirically, it describes the shifts in real estate ownership and changes in profit‐making strategies that have taken place across the real estate sector during the crisis years, and the role of the state in these shifts. The article asserts that the idea of spatial fixity representing a spatial barrier for accumulation does not necessarily apply in the Spanish case. It further claims that the tensions in capital circulation through real estate are not only to be found in the action of time, but in different state strategies pursued by various actors. The opposing representations of fixity are the result of state regulation of interest rates, taxation and risk weighting. The state also increasingly promotes land rents as a source of liquidity creation.  相似文献

This paper uses a spatial econometrics approach to study the industry risks in China’s stock market. We comprehensively consider the real linkage and information risk transmission channels and analyze the risk spillovers of specific determinants. Our empirical results show the following: 1) The real linkage channel and information channel are both effective transmission channels for driving spillover effects, and the information channel is of the utmost importance. 2) The spillover effects of specific determinants exist and are persistent. The superposition of spillover effects may lead to extreme risk. 3) The transmission channels and spillover effects are asymmetric in different regimes.  相似文献

Recent methodological developments provide a way to incorporate the temporal dimension when accounting for spatial effects in hedonic pricing. Weight matrices should decompose the spatial effects into two distinct components: bidirectional contemporaneous spatial connections; and unidirectional spatio-temporal effects from past transactions. Our iterative estimation approach explicitly analyses the role of time in price determination. The results show that both spatio-temporal components should be included in model specification; past transaction information stops contributing to price determination after eight months; and limited temporal friction is exhibited within this period. These findings highlight the decidedly non-linear temporal patterns of such information effects.  相似文献

This study investigates Chinese tourists’ views of nature, interest in animal experiences and their preferred natural landscape interpretation content from a generational perspective. Eight hundred and eight self-administered questionnaires were collected at Wulingyuan, a UNESCO World Natural Heritage Site, in China. It suggests that overall Chinese traditional cultural values and beliefs, notably the thinking of tian ren he yi (oneness of nature with humans), still have considerable impacts on Chinese tourists. They were found to have a strong sense of connection with nature and a preference for cultural interpretations of natural landscapes. Meanwhile, Chinese might be reaching a point of convergence in terms of attitude towards nature and animals with their Western counterparts, as reflected by their weak anthropocentric view, and strong ethical and aesthetic appreciation of animals, regardless of generation cohorts. Yet, the study shows significant generational gaps: older generations have a stronger connection with nature, are more concerned about environmental issues and show more support for the Western approach towards nature protection; the younger generations hold weaker anthropocentrism, and are more interested in animals, yet are less likely to learn about nature through tourism interpretation.  相似文献

本文利用全国592个国家级贫困县的数据,采用空间计量模型实证分析了普惠金融对县域资金外流的影响,并验证了贫困县资金外流是否会产生致贫效应。本文研究发现:如果普惠金融只注重解决贫困地区对金融机构的接触性排斥,会进一步加剧资金外流,对减贫产生负向影响,即存在显著的致贫效应。这种致贫效应具有明显的空间外溢性,邻近县域的贫困状况在很大程度上会彼此“传染”,并具有空间衰减特征的地理边界。因而需要客观认识普惠金融的本质,有针对性地选择恰当有效的实施载体,解决好对信贷产品等关键金融服务的使用性排斥问题。  相似文献

This paper estimates a spatial autoregressive (SAR) model of price dispersion using publicly available internet bookselling data. It uses a semiparametric adaptive estimator that does not require the usual Gaussian assumption of maximum likelihood (ML) estimators. The results suggest that both price competition and seller heterogeneity are key drivers of the observed price dispersion. The paper finds that sellers with large sales volume, newly established sellers and US mainland states-based sellers tend to price lower. The identified significant spatial interaction is evidence of spatial price competition. Controlling for everything else, a seller asks a lower price when large sellers charge relatively high prices, which is also evidence of price-based selling and undercutting.  相似文献

This study examines whether and how competitive experience affects gender difference in the preferences for risk and trust as well as academic performance. By utilizing the provincial differences in college admission rates as an indicator of competitive experience for students, we assess its relationship with gender difference in risk preference, trust preference, and academic performance. We find that females from provinces with lower college admission rates are more risk averse and less trustful, and perform better in more competitive environment, compared with their male counterparts. Our study suggests that observed gender differences may partially reflect the effects of schooling environment rather than inherent gender traits.  相似文献

Poor bank governance has disastrous consequences for economies as the 2007–2009 financial crisis has shown. In the aftermath, board diversity is identified as an effective mechanism to enhance bank governance. Diversity, creating cognitive conflict between board members, is expected to enhance board's independence of thought to better perform monitoring and advising functions. Age is a key demographic measure and age dissimilarity between the chair and the CEO in non-financial firms leads to better economic outcomes (Goergen, Limbach, & Scholz, 2015). In this paper, we examine whether chair-CEO age dissimilarity can mitigate banks' excessive risk-taking behaviour. Using a unique sample of 100 listed banks in Europe between 2005 and 2014, we find that age difference between the chair and the CEO reduces bank risk-taking. A chair-CEO generational gap –defined as a minimum of 20 years' age difference– has a larger impact in reducing risk-taking.  相似文献

国土空间用途的权衡决策方法研究   总被引:1,自引:0,他引:1  
研究目的:探索国土空间用途冲突协调路径,为中国"多规合一"及国土空间规划提供理论与方法指导。研究方法:在分析冲突根源的基础上建立国土空间权衡决策模型,构建"战略理性+技术理性+沟通理性"的国土空间权衡决策模式,并以丰县为例开展实证研究。研究结果:(1)国土空间利用的冲突本质上是利益相关者之间的利益冲突,只有利益权衡,没有利益优化;(2)国土空间权衡决策准则、国土空间价值评估、价值权衡和沟通定权共同组成国土空间权衡决策模式;(3)实证研究表明:经济发展战略下丰县镇村、农业、生态空间占比分别为18.51%、74.20%、7.29%,粮食安全战略下占比分别为16.07%、76.66%、7.27%,生态文明战略下占比分别为17.88%、69.06%、13.06%,权衡结果较合理。研究结论:国土空间权衡决策受国家战略驱动、以沟通为基础、以技术为手段,可有效解决国土空间用途冲突问题。  相似文献
