政治关联和融资约束:信息效应与资源效应

本文探讨政治关联缓解民营企业外部融资约束的微观作用机理。经验证据表明,政治关联确实能缓解企业融资约束,其核心机制在于信息效应和资源效应。政治关联能够起到信号发送功能,降低资金供求双方的信息不对称,这就是政治关联的信息效应;同时,政治关联有助于强化民营企业的资源获取能力,切实提高企业的未来总收益,这就是资源效应。经验研究还表明,资源效应占主导地位,政治关联缓解民营企业融资困境的关键在于资源效应。因此本研究的一个直接政策涵义就是,要解决目前民企融资难的问题,当务之急是要构建公平的市场环境,消解政策性歧视,给予所有企业同等的资源获取机会。     

外层网络资源获取、制度环境与孵化器创新绩效研究

以国家级科技企业孵化器面板数据为样本，构建FGLS计量模型，研究外层网络资源获取能力对孵化器创新绩效的影响。结果发现：孵化器外层网络资源获取能力与创新绩效显著正相关，地区总体制度环境对外层网络资源获取能力与孵化器创新绩效间关系具有显著正向调节作用。同时，通过对政府治理水平、法制化水平和产品市场发育程度3个方面制度子环境调节作用的进一步检验发现，地区制度环境调节机制主要体现为对创新激励和创新效率的促进作用。研究揭示孵化器主观网络支持获取与客观地域制度环境相互作用，共同影响孵化器创新绩效，从而为提高孵化器创新绩效拓宽了管理视角。     

Resource use in patients hospitalized with complicated skin and soft tissue infections in Europe and analysis of vulnerable groups: the REACH study

Background:

Hospitalized patients with complicated skin and soft tissue infections (cSSTI) present a substantial economic burden, and resource use can vary according to the presence of comorbidities, choice of antibiotic agent, and the requirement for initial treatment modification. REACH (NCT01293435) was a retrospective, observational study aimed at collecting empirical data on current (year 2010–2011) management strategies of cSSTI in 10 European countries.

Methods:

Patients (n?=?1995) were aged ≥18 years, hospitalized with a cSSTI and receiving intravenous antibiotics. Data, collected via electronic Case Report Forms, detailed patient characteristics, medical history, disease characteristics, microbiological diagnosis, disease course and outcomes, treatments before and during hospitalization, and health resource consumption.

Results:

For the analysis population, mean length of hospital stay (including duration of hospitalizations for patients with recurrences) was 18.5 days (median 12.0). Increased length of hospital stay was found for patients with comorbidities vs those without (mean?=?19.9; [median?=?14.0] days vs 13.3 [median?=?8.0] days), for patients with methicillin-resistant Staphylococcus aureus compared with patients with methicillin-sensitive S. aureus (mean?=?27.7 [median?=?19.5] days vs 18.4 [median?=?13.0] days) and for patients requiring surgery (mean?=?24.4 [median?=?16.0] days vs 15.0 [median?=?11.0] days). Patients requiring modification of their initial antibiotic treatment had an associated increase in mean length of hospital stay of 10.9 days (median?=?6.5) and additional associated hospital resource use. A multivariate analysis confirmed the association of nosocomial infections, comorbidities, directed treatment, recurrent infections, diabetes, recent surgery, and older age (≥65 years), with longer hospital stay.

Conclusions:

This study provides real-life data on factors that are expected to impact length of hospital stay, to guide clinical decision-making to improve outcomes, and reduce resource use in patients with cSSTI.     

科技金融政策促进科技企业发展的资源配置效率研究——来自北京市的实证调查

以北京市科技企业为调查对象，对科技金融政策促进企业发展的资源配置效率进行问卷调查分析，结果发现：各分项政策效率由高到低排序依次为财政补贴、金融监管、服务平台、税收优惠、科技保险、风险投资、科技担保、科技信贷政策；政策资源配置在不同产权类型、注册资本、行业类型、员工规模、资质类型、成立年限和年营业收入之间的均衡程度不同；政策激励偏重于创业明朗期和成熟期实力雄厚的企业、区级高技术企业以及国家战略扶持或市场需求较强行业，对创业危险期和成长转型期企业、市级高技术企业、风险较高行业激励性较弱。因此，建议政策优化时处理好以下关系：助强与扶弱、需求与供给、优先与平衡、创业与后劲、管制与放开、独立与协同。

Determinants of voluntary environmental management practices by MNE subsidiaries

There have been few empirical studies of the determinants of voluntary environmental management practices (VEMPs) of MNE subsidiaries operating in emerging countries. To provide insight on this issue, this study explores the antecedent factors that drive MNE subsidiaries to adopt VEMPs, using data drawn from a key emerging country – Turkey. Based largely on the arguments of institutional theory and the resource based view of the firm, a number of hypotheses are formulated in order to investigate the effects of stakeholder pressures, perceived polluting potential, customer focus and competitive intensity. Each of these factors, with the exception of competitive intensity, is found to positively influence the adoption level of VEMPs by MNE subsidiaries. Some of the study's parent-level and subsidiary-level control variables are also found to have significant effects on the extent of VEMPs adoption by MNE subsidiaries.     

长春市文化养老消费市场发展实证研究

文化养老关注老年人的精神和情感需求,是我国优秀传统文化与当代人文关怀的有机融合。选取长春市老年居民消费及收入相关数据并利用门限回归模型,实证分析收入水平与老年人文化消费之间的影响效应。研究结果表明,长春市老年人文化消费与收入水平之间存在明显的非线性特征,不同收入阶层老年人的文化消费偏好存在差异;老年人个体异质性对其文化消费存在显著影响。因此,要有效推动长春市老年人文化产业的发展,一方面,应注意挖掘低收入群体老年人的文化消费潜力,设计符合该群体老年人文化消费特点的产品,并施以政策支持;另一方面,更加注重高收入组群老年人个体异质性对其文化消费的影响,设计满足其个性化文化消费需求的产品,从而满足老人们日益增长的精神需求,提高老年人的生活质量。     

Is online education more like the global public goods?

Nowadays with the possibility of synchronous e-learning, online courses are becoming a new paradigm in education. But there are few studies systematically discussing the interplay between online courses and global education equality quantitatively. Here, we indicate that online education is more like the global public goods with on-rival and non-excludable in consumption. We establish an educational outcome model and indicate that popularity of online education is likely to give rise to the human capital augmentation, both for developing and developed countries. And this growth stems from the characteristics of global public goods. To analyze the possibility of the potential growth, we suggest that an online education club would help countries to escape from the dominant strategies of “Free ride”, which is the common dilemma in public goods supply. So the cooperation would bring coordinated growth to countries with different advantages in educational resources. And this win–win situation offers an underlying driving force to the development of human capital and economics. This paper provides a view offering the deep understanding on reducing the gap of education outcome between countries, and get a coordinated development in the Internet or MOOCs Era. It gives more supports to the development of online education in the future.
