在梳理国内外BIM采纳与扩散相关研究的基础上,从新制度主义理论出发,提出了水利水电工程组织场域并分析了其特征;进而运用技术-组织-环境(TOE)框架和匹配理论,分别讨论了水利水电工程组织场域BIM扩散的主要影响因素,形成一个整体的理论分析框架。分析表明,水利水电工程组织场域BIM扩散的影响因素主要包括:相对优势、兼容性和复杂性等技术因素,组织沟通、资源就绪度和高层领导支持等组织因素,以及制度环境、市场环境等环境因素。 相似文献

木质家具是我国最重要的出口林产品之一。人民币汇率改革后,人民币总体呈升值趋势,这一趋势提高了国产木质家具的出口价格,会产生阻碍出口的作用;与此同时其也会使进口原材料价格相对降低、促进原材料的进口,二者相互作用会共同影响木质家具出口额。通过建立回归模型,研究人民币汇率波动对中国木质家具出口贸易额的影响,结果表明人民币汇率与中国木质家具出口额呈负相关,但是通过人民币贬值来促进出口的策略并不明智。 相似文献

This study examines whether signing auditors from rice planting regions affect audit quality. Using a sample of 12,223 firm-year observations from the Chinese stock market over the period of 2004–2015, our findings reveal that signing auditors from rice regions are significantly negatively associated with the likelihood of unclean audit opinions, suggesting that signing auditors with rice culture are more likely to succumb to the managers and hamper independence, and thus are more inclined to issue favorable audit opinions, and eventually impair audit quality. Furthermore, audit firm size and industry expertise attenuate the negative relation between signing auditors with rice culture and audit quality. In addition, above findings are robust to a variety of sensitivity tests using different measures of audit quality and signing auditors from rice cultivating areas and our conclusions still stand after using the Heckman two-step approach, placebo test and differences-in-differences method to address the potential endogeneity problem. 相似文献

Culture has been known to play an important role in explaining differences in consumption behaviour across countries. Yet, we know very little how it affects spending on non-life insurance products. This paper attempts to shed some light on how cultural characteristics impact the demand for property, accident and health insurance, focusing on the OECD countries in the period 2000–2017. We find, via the system generalized method of moment estimations, that cultural characteristics such as individualism, long-term orientation, masculinity and uncertainty avoidance were the drivers of the expenditure on property insurance, whereas long-term orientation, uncertainty avoidance and hypometropia explained accident and health insurance spending across the OECD countries. In the presence of the global financial crisis, cultural effects on property insurance spending turned out to be relatively minor, with the exception of individualism. These findings provide valuable information for non-life insurance companies, consumers and policy makers in the OECD countries. 相似文献

In Australia and in many parts of the world, older people participate in line dancing. Our phenomenological study explored whether attending a regular line dancing class might offer a group of older people opportunities for active and successful ageing. Our research investigated the meanings and practices fostered in a community line dancing class in Melbourne. We gathered data via an interview with the teacher of the group, observation of a class and two focus group interviews with 25 members. Data were analysed using Interpretative Phenomenological Analysis that is reported thematically under headings of: Belief in the efficacy of line dancing, Physical and emotional benefits, YouTube clips as instructional reinforcement and promotion, and Socialising. The findings show that participation in the class offered older student’s opportunities for dance and music engagement, active and successful ageing, health and well-being, social connection and purposeful leisure. The teacher of the class modelled serious and successful leisure and advocates for dance as holistic training for older people. We position our participants on a continuum of leisure engagement that ranges from the casual to the serious. Further research is required to support arguments for the efficacy of dance as a leisure pursuit for older adults. 相似文献

自然资源资产管理:理论逻辑与改革导向 总被引:1,自引:0,他引:1
研究目的:针对自然资源资产管理的理论诠释不清、改革导向不明、自然资源的资产属性尚未充分体现等问题,本文立足新时代党和国家机构改革背景,分析自然资源资产管理的理论逻辑,明确未来自然资源资产管理的改革方向。研究方法:文献研究法,综合分析法。研究结果:新时代自然资源资产管理应当基于"权利—价值—经营—管理"的理论逻辑体系框架,其中自然资源资产权利应当包含自然资源资产所有权、资格权、使用权和管理权等对象内涵,以完整、明晰和稳定作为权利实现要求;自然资源资产价值显化应当基于生态、经济等价值的全面认知,针对不同资产类型分类采用不同价值评估方法,完善市场培育、价值调节和公平分配机制;自然资源资产经营既要保障粮食安全、生态安全和规避可能风险,又要实现高品质利用,因而应当以底量保安全,以存量、数量、质量、差量和流量保协同,优化完善编制资产负债表;自然资源资产管理则应当打破自然资源资产管理割裂的现状,实现系统统一管理并建立全平台、全过程、全资源和全空间的综合监督机制。研究结论:自然资源资产管理应以"三维立体多权化"、"生态价值具象化"、"安全品质六量化"和"系统监管综合化"为改革导向,以期全面推进未来多维、绿色、高效、安全、品质、有序的自然资源资产管理方式的切实实现。 相似文献

This paper investigates the impacts of different network ties on export propensity of Vietnamese small and medium enterprises (SMEs) in the manufacturing sector. Using data from a survey of over 2,600 manufacturing SMEs in 2015, we found that social networks contribute positively to the export propensity of SMEs, while the size of business networks negatively associates with the likelihood of export. However, bank networks and political networks are not significant for the propensity to export of Vietnamese SMEs. We discuss the results in detail and offer recommendations for SME owners, managers and policy makers. 相似文献
