基于253家浙江省众创空间的微观数据,文章在运用连续距离的测度方法测算众创空间集聚水平的基础上,采用零膨胀负二项回归等方法实证分析众创空间集聚的影响机制。研究发现,众创空间的地理分布存在显著的区域差异,主要分布在杭州和宁波市辖区,选址具有明显的集聚特征。回归结果显示,区域创新能力和生态环境均对众创空间的地理集聚具有促进作用,但两者之间存在明显的替代效应;尽管不能直接促进众创空间的集聚,政策引导与创新能力之间具有较显著的互补效应。据此,文章从培育创新能力和优化创新激励等方面提出了政策建议。 相似文献

尽管有研究表明社会资本与服务业集聚是服务企业绩效提升的关键因素,吸收能力在社会资本和集聚在企业绩效之间起了中介作用,却鲜有文献深入揭示社会资本、集聚、吸收能力以及企业绩效运作机理。以广东为主的129家服务企业为样本,采用结构方程对其进行实证分析。结果显示,内部社会资本与实现吸收能力显著正相关;集聚度与企业潜在吸收能力显著正相关;外部社会资本与潜在吸收能力以及实现吸收能力均显著正相关。内部社会资本与外部社会资本有共生关系;集聚度与外部社会资本有共生关系,与内部社会资本无显著正相关关系;集聚度及社会资本通过吸收能力中介作用影响企业绩效。 相似文献

经典资本结构理论认为债务具有税盾效应和财务杠杆效应,因此公司会选择适当的负债以获得债务的税收收益。但是,现实中一些公司的负债很低,甚至为零。公司为什么放弃债务的税收收益呢?本文以2007~2011年中国A股上市公司为研究样本,从行为公司金融的视角分析管理者能力是否导致公司采用“低杠杆”策略。结果表明,中国上市公司存在普遍的低杠杆现象,管理者能力的差异是导致公司采用“低杠杆”策略的重要原因。 相似文献

大众传播媒介及农业信息服务网络通过环保信息传播可在潜移默化中培养农户的亲环境价值观,进而影响农户的亲环境行为。基于信息传播培养理论,整合计划行为理论和“信念—价值—规范”理论构建亲环境行为理论模型,并采用甘肃省19个县(区)542户样本农户的调研数据进行验证,结果显示:环保信息的有效传播可以潜移默化地强化农户的亲环境价值观,农户的亲环境价值观、行为态度、主观规范、知觉行为控制及责任归属均对其亲环境行为有显著的正向预测作用,农户经营规模和专业化水平对其亲环境行为也有显著正向影响。应提高农户生产经营的规模化和专业化程度,加强对农户亲环境价值观及主体责任认知、亲环境行为知识和技能等方面的教育和培训,并充分发挥农村干部、党员、能人等的带头示范作用,以有效促进农户亲环境行为。 相似文献

This article aims to improve the predictive ability of KMV model by distinguishing firm size. The evidence suggests that default point would vary with firm size. Using the method of particle swarm optimization, we obtain the optimal default point separately for large firms and small firms. Several statistical tests such as the model confidence set methodology show that our relatively tractable model is more likely to have the strongest predictive ability. 相似文献

Given the importance of communication in the realm of corporate associations, this study analyzes the roles that communication strategies play in the formation of corporate associations. The study examines (1) whether particular types of associations (corporate ability or corporate social responsibility associations) can be developed through CA- or CSR-based communication strategies, and (2) the relative effectiveness of these two association types at amplifying favorable consumer responses across three different industries (consumable goods, durable goods, and stigmatized goods). An experiment was conducted to test the proposed model with six Fortune 500 companies. The results demonstrate that communication strategies can effectively facilitate a particular type of association. Differing levels of association effectiveness were found within each industry. For the consumable goods industry, CA associations are found to be more effective than CSR associations. For the durable goods industry, CSR associations are more influential at enhancing consumer attitudes and purchase intent than CA associations, while CA associations have a larger impact on supportive communication intent. In the case of the stigmatized industry, CSR associations play a determinant role in fostering positive consumer responses. This study provides managers and communication specialists with more concrete guidance for choosing a particular corporate positioning and communication strategy. 相似文献

Despite the vast literature surrounding various aspects of left behind children (LBC)’s development in China, very few studies have examined the development of, and impact on their non-cognitive abilities as a result of parental migration. Using survey data consisting of 5002 eighth graders from 160 middle schools in northwestern China, this paper investigates how parental migration affects children’s non-cognitive abilities, as is measured by Big Five components of conscientiousness, extraversion, neuroticism, agreeableness, and openness, as well as children’s grit. We narrow our analysis to long run and short run migration subsamples and use the propensity score matching method to address the potential selection bias issue. Our results show that mother’s migration is particularly harmful to the development of children’s non-cognitive abilities, as mother is usually the primary caregiver and mother’s migration makes less economic contribution to the family. In the long run, LBC with migrant mother tend to have lower levels of conscientiousness and grit; they also have higher level of neuroticism (or lower level of emotional stability). In the short run, when mother migrates, children tend to have lower levels of conscientiousness, agreeableness and openness. 相似文献

Recent researches have shed light on the effect of cognitive ability on economic decision-making. By measuring cognitive ability applying Raven's progressive matrix test, we obtain two significant results that this effect affects decision-making in two types of experimental ultimatum games. First, the higher the cognitive ability, the larger the amount a sender offers when the offer is smaller than or equal to the half split. Second, the higher the responders’ cognitive ability, the smaller the offer they accept, when they accept it or not with the strategy method. This study not only finds new factors that affect decision-making in experimental ultimatum games, but also provides more evidences that cognitive ability influences economic decision-making. 相似文献
