房屋土建工程质量监督管理问题与强化建议探究

随着社会经济的快速发展,我国的房屋建筑工程也随之发展起来。建筑施工中无论是技术还是人员的配置都日趋合理,但同时一些问题也逐渐显现出来,如工程施工人员的素质水平不高、建筑市场混乱等,使得工程质量受到了影响,所以我们必须要加强对房屋土建工程的质量监管。     

How entrepreneurs recognise entrepreneurial opportunity and its gaps: a cognitive theory perspective

ABSTRACT

Previous studies have verified the relationship between entrepreneurial opportunity recognition and performance. However, the influences of a perceived gap between entrepreneurial opportunities before and after launching a new venture have been neglected. This study applied the partial least square method to analyse the entrepreneurial behaviours and performance of 214 Taiwanese new ventures, and adapted the bootstrap re-sampling method for estimating the variables. The empirical results showed that entrepreneurial resource and entrepreneurial alertness significantly influence the perceived opportunity, while the entrepreneurial resource significantly affects the actual opportunity. The results further demonstrated that both the perceived opportunity and actual opportunity considerably influence new venture performance. This study offered a research framework to better understand the cognition path of entrepreneurial opportunity, and suggested the factors affecting the recognition of perceived opportunity by longitudinal method can be further evaluated. To improve performance, entrepreneurs should enrich entrepreneurial resources and allocate them appropriately, and heighten and maintain their alertness to reduce the perceived gap arising from recognising entrepreneurial opportunities.     

Search within or beyond the industrial cluster? The effect of perceived competition and knowledge base tacitness on strategic location choices of external knowledge search

ABSTRACT

From a knowledge-based perspective, this paper highlights the need for a framework linking perceived competition of the industry and firms’ strategic location choices of external knowledge search and examines whether the perceived competition increases the propensity of cluster firms to search more widely from extra-cluster knowledge sources than intra-cluster knowledge sources. Furthermore, we emphasise that cluster firms with varying degrees of tacitness in their knowledge base might respond to such competition differently when conducting external knowledge search activities. Using a sample of 310 cluster firms in the Zhejiang Province of China, we find that the cluster firm would increase the propensity for more geographic boundary-spanning search relative to local search while under the pressure of competition. Moreover, the positive relationship between perceived competition and the propensity towards geographic knowledge search is weaker when the tacitness of the cluster firm’s knowledge base is higher. The findings contribute to the understanding of the relationship between competition and the choice of location strategies in external knowledge search.     

高校知识溢出与企业创新绩效

本文利用全样本数据探讨了作为创新和知识溢出微观主体的高校对企业创新绩效的影响。本文通过ArcGIS测算了2007-2015年上市公司所在地周边全部高校数量，并以企业研发投入金额、发明专利衡量企业创新水平，利用Anselin et al（2000）的KPF方程，采用双聚类OLS检验高校知识溢出对企业创新行为的影响效应与机制。研究发现：第一，高校知识溢出对企业研发创新投入和有效创新产出均具有显著促进作用；第二，知识溢出效应具有显著的地理邻近性特征，而行政边界关联影响较弱；第三，高校知识溢出通过提高企业研发投入，提升员工和管理层人力资本，进而影响企业创新绩效。进一步研究表明，空间异质性、高校异质性、企业异质性、中心城市集聚效应、高铁开通等因素导致高校知识溢出效应存在差异。     

《经济地理》创刊以来的知识溢出特征与变化

基于引证关系,利用知识图谱、社会网络分析等方法,对1981—2019年《经济地理》创刊以来知识溢出的特征与变化规律进行分析。经济地理学研究的专业综合性、学科交叉性特点,在《经济地理》期刊知识溢出的特征与变化中得以充分诠释。期刊知识溢出的作用与变化,不仅体现在促进作者合作网络形成与机构合作关系的深化上,也体现在对城市化、区域经济发展、区域旅游发展等研究领域的推动作用与变化上。期刊知识溢出的特征与变化在其主题构成、作者贡献、机构力量与前沿引领等的探讨中进一步得以明确。具体地,城市化研究的知识溢出作用,从城市化和城镇化、土地利用、生态环境等方面,逐渐转向新型城镇化、城市网络、生态环境、协调发展等主题;区域经济发展研究的知识溢出作用,经历了从经济联系转向产业集群、再转向空间相互作用关系的主题变化;区域旅游发展研究的知识溢出作用,则从旅游资源、旅游业、生态旅游等方面,逐步转向乡村旅游、旅游经济与协调发展等主题。以国家战略与发展政策为主要导向,促进国内经济地理学的研究与发展,是《经济地理》期刊知识溢出的核心内容与集中反映。     

To Empower or Not to Empower? Multilevel Effects of Empowering Leadership on Knowledge Hiding

It is widely acknowledged that knowledge hiding persists and has detrimental effects in service organizations. With organizations increasingly becoming team based, understanding the interactions between supervisor and team members especially how team- and individual-level empowering leadership behaviors influence followers’ knowledge hiding is important. Using data on 527 followers from 60 departments in 19 Chinese hotels, the study proposes a multilevel model to examine the manifestation of two types of empowering leadership (individual-focused and differentiated empowering leadership) and the dual-level processes on followers’ knowledge hiding. Results show that differentiated empowering leadership is positively related to followers’ knowledge hiding via group relational conflict, whereas individual-focused empowering leadership is negatively related to followers’ knowledge hiding via their psychological safety. In addition, follower’s psychological safety buffers the positive relationship between group relational conflict and followers’ knowledge hiding. We discuss the implications on both theory and practice of empowering leadership on knowledge hiding.     

Give mind to the gap: Measuring gender differences in financial knowledge

Prior research consistently finds a gender gap in financial knowledge where males appear to outperform females. Despite the wealth of studies attempting to explain this gap, none have considered whether the gender gap may be a product of measurement method. This study re-examines the gender gap with item response theory (IRT) which can account for guessing behavior and differential item functioning. Survey data on 184,869 individuals from 39 countries and territories is analyzed. Results show that when IRT is employed, a gender gap exists in only 54% of the sample. In contrast, when a conventional measurement approach is used, there is a gender gap in financial knowledge in 81% of the sample. These results reveal that prior measurements may underestimate women's financial knowledge and inflate the gender gap.     

Immigrants,Financial Knowledge,and Financial Behavior

This research seeks to identify gaps in financial knowledge and behaviors between immigrants to Canada and individuals who are born in Canada. The research aims to evaluate to what extent immigrants involve themselves in financial planning and avoid harmful financial behaviors. Employing the Canadian Financial Capability Survey (2009), the findings of the study suggest that immigrants are less likely to show high levels of financial knowledge compared to born citizens. The knowledge gap between immigrants and born citizens narrows as an individual resides longer in Canada. In addition, immigrants are less likely to prepare themselves financially for their retirement or to have long-term investments. The findings provide a basis for addressing the implications of weak financial knowledge.     

Illusion of safety: How consumers underestimate manipulation and deception in online (vs. offline) shopping contexts

Online commerce changes how consumers shop for products and services—while also giving firms more control over consumers' shopping experience, more access to their information, and leading more firms to use these platforms to their financial advantage. In this research, I examine consumer perceptions of firms when they shop for products and services online (vs. offline), to determine whether consumers feel firms might use certain kinds of manipulative and deceptive tactics against consumers. Results show consumers believe firms are less likely to use manipulative and deceptive practices to increase consumer spending, when they shop online (vs. offline) for products and services. These findings remain consistent despite key individual differences (in ethnicity, gender, age, and time spent online). This research also demonstrates how certain cues can make consumers more (vs. less) suspicious of firms when they shop online and discusses the implications these findings have for consumer financial welfare.
