众创空间类型如何塑造创业服务行为？基于制度逻辑视角的分析

文章基于制度逻辑视角,以浙江省746家众创空间为样本,分析了政府、高校、民营企业三类主体设立的众创空间和创业服务行为选择的关系。研究发现：（1）制度逻辑对众创空间的创业服务行为选择具有塑造作用,持有行政逻辑的政府型众创空间会将时间更多的分配给办公场所服务,而持有专业逻辑的高校型和持有公司逻辑的民企型众创空间,则分别会将时间更多的分配给培训咨询服务和投融资服务。上述发现在替换了其它两种因变量测量指标后依然成立。（2）国家级认证会使民企型众创空间显著减少在投融资服务上的时间分配比重,而显著增加在办公场所服务和培训咨询服务上的时间分配比重,这种调节效应在另外两类众创空间中并不显著,在替换了省级认证后结果依然成立。这表明,相较于公司逻辑,政府逻辑和专业逻辑更具稳定性,更不易受高阶制度因素的影响和干扰。文章拓展了制度逻辑和众创空间创业服务行为关系的理论认识,为创业者的众创空间入驻决策以及政府针对众创空间的政策制定提供了实践启示。     

Managing leverage of infrastructure projects: Aggregate and sectoral risk effect

Funding for infrastructure projects recently shows that debt has a portion more than equity, triggering public debates. Therefore, leverage as an instrument to measure the ability and willingness of project sponsors to fund becomes the utmost importance to discuss. Relating to leverage, risk and government participation are two main factors that can explain the choice of funding decisions by the project sponsors. For this reason, this study would analyze the effect of risk and government participation on leverage through the two main sectors of infrastructure projects, namely the transportation sector and the energy sector, and derivating risk to political risk and financial risk. The objects of research were 976 infrastructure projects listed in the Asian Development Bank during 2007−2016. We use censored regression to examine the model by infrastructure sectors, both as individual and through interaction effects. The analysis showed that overall, leverage of infrastructure projects was rather influenced by financial risk than by political risk. However, the leverage of infrastructure projects in the transportation sector was more vulnerable to risk than that in other sectors.     

地方政府人才引进政策促进了区域创新吗？——来自准自然实验的证据

高技能人力资本对于我国经济转型的重要性不言而喻。本文以2009—2012年间39个城市集中出台的地方人才引进政策为准自然实验,采用多期政策的双重差分法,结合机制分析和异质性分析,探究了人才政策出台前后区域创新能力的变化及其背后的机制和深层次原因,并分析政策效应在不同的地区营商环境、科教事业投入力度、知识产权保护程度下的差异。本文主要结论包括,地方人才引进政策总体上提高了当地的专利授权总量和专利价值总量;显著增加了研发投入的规模,但创新效率没有得到明显提升;在营商环境较差的地区,政策的效应侧重于提高专利数量,营商环境较好的地区则侧重于提升专利价值;在科教投入力度本身就很大的地区,政策效果较小,在科教投入弱的地区效果会更明显;在知识产权保护程度弱的地区,政策效果更多地表现为提高专利数量,保护程度强的地区,则侧重于提升专利价值。上述结论对地方政府优化人才激励政策、实施创新驱动发展战略具有一定的政策启示。     

政策不确定性对公司投融资行为的影响研究

本文以2003-2013年中国A股上市公司的财务数据和31个省市自治区地方官员的变动数据为样本,采用地方官员变动率作为地方政策不确定性的代理变量,研究了政策不确定性对企业投融资的影响。研究发现,政策不确定性显著降低企业的债权融资,但是对股权融资影响不显著。政策不确定性对企业投资的影响存在两种渠道,一是通过降低企业融资来影响投资,二是通过企业资本运作降低融资对投资的影响系数,即政策不确定性越高,企业债权和股权融资对投资的正向作用会越小,这种作用机制在国有企业、大企业等与政策联系紧密的企业中作用更为显著。融资可获得性是政策不确定性影响投资的重要前提之一,融资可获得性较小时,政策不确定性显著降低了企业投资;在融资可获得性较大时,政策不确定性影响不显著。加强长期制度建设,降低政策不确定性,对于稳增长具有重要意义。     

Government support and bank performance during the 2007–2008 financial crisis

Though previous studies suggest a state participation has a negative impact on banks, this paper highlights the potential benefits of state ownership for confidence and stability in the post-crisis period that can outweigh the inefficiencies and potential for corruption of political intervention. We find that the state guarantees are valuable during the crisis. The negative (positive) relation between state ownership and bank profitability (risk) is mitigated in the post-crisis period. Financially troubled banks that receive a transfer payment or capital injection experience improved performance during the post-bailout period.     

A social-media-based approach to assessing the effectiveness of equitable housing policy in mitigating education accessibility induced social inequalities in Shanghai,China

Social inequalities induced by education accessibility are widespread and concern land use policy makers globally. Yet much of existing research heavily emphasizes on uncovering the spatial patterns of housing price in relation to education resources. This paper aims to renew our understanding of this classical topic by bringing the importance of temporal and institutional dynamics to the fore. Specifically, this research presents a detailed examination of the relationship between school quality and housing rental dynamics under the intervention of equitable housing policy, with special reference to Shanghai, the most developed megacity in China, also one of the first Chinese cities granting equal rights for renters to access schools within the catchment area. Based on time-series housing rental data collected from social media, the t-test discovers that school quality has a significant impact on housing rental prices after the introduction of this new housing policy. Moreover, housing rental prices within high-quality school districts are significantly higher than those within ordinary school districts. The hedonic model and variance partitioning further confirm that school quality is capitalized into housing rental prices, and its relative contribution varies with temporal periods. More specifically, how the relative contribution of school quality changes over time is consistent with the schedule of primary school enrollment and sensitive to policy intervention. The difference in difference model foregrounds that the equitable housing policy does result in rental prices hike in high-quality school districts, i.e., a 13.5 % rental premium of housings within high-quality school districts compared with those within ordinary ones. We conclude that the equitable housing policy fails to achieve the expected goal and propose alternative suggestions for mitigating social inequalities in education accessibility. This study demonstrates a novel methodological framework for evaluating the social consequence of equitable housing policy based on social media data. It unravels how housing rental changes with school district division and the capitalization effect of school quality in housing rental prices.     

Forecasting the urban skyline with extreme value theory

The world’s urban population is expected to grow fifty percent by the year 2050 and exceed six billion. The major challenges confronting cities, such as sustainability, safety, and equality, will depend on the infrastructure developed to accommodate the increase. Urban planners have long debated the consequences of vertical expansion—the concentration of residents by constructing tall buildings—over horizontal expansion—the dispersal of residents by extending urban boundaries. Yet relatively little work has predicted the vertical expansion of cities and quantified the likelihood and therefore urgency of these consequences.We regard tall buildings as random exceedances over a threshold and use extreme value theory to forecast the skyscrapers that will dominate the urban skyline in 2050 if present trends continue. We predict forty-one thousand skyscrapers will surpass 150 meters and 40 floors, an increase of eight percent a year, far outpacing the expected urban population growth of two percent a year. The typical tall skyscraper will not be noticeably taller, and the tallest will likely exceed one thousand meters but not one mile. If a mile-high skyscraper is constructed, it will hold fewer occupants than many of the mile-highs currently designed. We predict roughly three-quarters the number of floors of the Mile-High Tower, two-thirds of Next Tokyo’s Sky Mile Tower, and half the floors of Frank Lloyd Wright’s The Illinois—three prominent plans for a mile-high skyscraper. However, the relationship between floor and height will vary considerably across cities.     

内部控制、僵尸企业与审计特征

以2010—2017年深沪两市全部A股上市公司为研究样本，分析僵尸企业的审计特征并探讨内部控制对两者关系的调节效应。研究发现：相比于非僵尸企业，僵尸企业具有倾向于支付更低的审计费用、更有可能收到非标意见和更有可能选择非高质量审计师进行审计的特征，同时，僵尸企业内部控制环境更差。进一步研究发现，更高的内部控制质量使得僵尸企业更有可能收到标准无保留的审计意见，但非僵尸企业审计收费更高且更有可能选择高质量审计师。基于产权性质的进一步研究发现：（1）国有僵尸企业支付更低的审计费用，且中央国企支付的审计费用更低；（2）民营僵尸企业更有可能收到非标审计意见；（3）民营僵尸企业和地方国有僵尸企业更有可能选择非高质量审计师进行审计，且地方国有僵尸企业倾向性更强。从公司治理角度研究僵尸企业的审计特征，为识别僵尸企业提供了经验证据。     

General or central government? Empirical evidence on political cycles in budget composition using new data for OECD countries

Previous studies used general government data to examine whether national governments’ electoral motives and ideology influenced budget composition in OECD countries. General government data includes, however, the state and local level. Using new data for general and central government over the period 1995–2016, I reexamine political cycles in budget composition. The results suggest that, both at the general and central government level, leftwing governments spent more on education and less on public services than rightwing governments. Defense expenditure was somewhat lower under leftwing than rightwing governments and in election years; especially in federal states. Effects of government ideology on the individual expenditure categories are larger at the central than general government level. Scholars need to re-examine results on ideology-induced effects that have been derived from general government data where central government data should have been used.     

Changes in tourists’ perception of well-being based on their use of emotion regulation strategies during vacation

ABSTRACT

Based on the theoretical foundation of emotion regulation, this exploratory study aimed to examine changes in tourists’ perceived well-being and to determine whether these changes were due to use of emotion regulation strategies (ERSs) during their vacation. This study used travel diaries to record tourists’ use of ERSs on a daily basis, and also measured tourists’ perceived well-being one day before and after their vacation. Results indicated that tourists had significantly higher perceptions of well-being after vacation, and those who used ERSs were more likely to indicate a higher sense of well-being after vacation. The results provide new insight into which aspects of tourists’ subjective and psychological well-being can be boosted by taking vacations and how these aspects may be enhanced by using different ERSs.
