局部平稳部分线性面板数据模型的统计推断

部分线性模型是一类非常重要的半参数回归模型,由于它既含有参数部分又含有非参数部分,与常规的线性模型相比具有更强的适应性和解释能力。文章研究带有局部平稳协变量的固定效应部分线性面板数据模型的统计推断。首先提出一个两阶段估计方法得到模型中未知参数和非参数函数的估计,并证明估计量的渐近性质,然后运用不变原理构造出非参数函数的一致置信带,最后通过数值模拟研究和实例分析验证了该方法的有效性。     

Local mobilisations and the formation of environmental networks in a democratizing Tunisia

ABSTRACT

This study examines the environmental protests that occurred in Tunisia after the 2011 uprisings. It analyses the factors underpinning the rise of the environmental networks during the period of transition (2011–2014). It details the mobilising strategies that were crucial for the networks’ growth or survival during this period of institutional instability. The study shows how networks leaders were able to bring together social and political actors from different backgrounds and ideological orientations. It is argued that the ability of networks to develop new distinctive collective identities was crucial for network sustainability. Those networks and actors who did not develop new clearly defined environmental identities and continued to rely importantly on pre-existing (authoritarian) structures and practices were more negatively impacted by ideological cleavages and political calculations. Empirically, the contribution builds on interviews and observations, as well as documents collected from Tunisian municipalities between 2013 and 2015. Conceptually, the research proposes a bottom-up perspective that highlights the interplay between micro- and macro-dynamics and strategies during a political transition. The analysis details the actors’ capacity to build alliances via interpersonal relations at the micro level, and their strategies to engage with institutional actors and processes.     

地方政府公共服务创新实践的发展与生成逻辑

不断推动地方政府公共服务创新是未来实现中国基本公共服务均等化和供给侧结构性改革目标的重要途经。系统梳理历届“中国地方政府创新奖”下公共服务创新类获奖项目的相关文本，探究当前中国地方政府公共服务创新实践发展和生成逻辑。具体涉及地方政府公共服务创新在时间跨度、地域分布上的外在特征，创新类型、创新方式与供给机制的内在结构，其中制度支持、社会需求和政策企业家是地方政府公共服务创新生成的重要基础。在未来中央政府应给予地方政府更多的公共服务创新空间，地方政府在公共服务创新中应更多地考虑群众公共服务需求、接纳社会组织的参与，同时应吸纳更多的体制内和体制外政策企业家来推动创新的持续发展。     

人工智能辅助地方立法的应用与规制

我国地方立法权随着2015年《立法法》的修改扩至所有设区的市，随之掀起地方立法热潮。但目前地方立法的质量普遍不高，存在诸多问题，人工智能技术的应用能为地方立法开辟新路径。基于互联网及大数据的人工智能，能被应用于资料检索、立项论证、立法公开与意见征集、辅助草案起草、立法后评估与备案审查。与此同时，当人工智能被应用于地方立法工作时，需要确立“辅助原则”，规范人工智能地方立法程序的选用标准，限制人工智能地方立法程序的算法，以此来规制人工智能带来的不利影响。     

地方高校推行教师学术休假制度的现实意义与实施策略

教师学术休假是促进教师专业发展的重要形式，是教师自我完善的需要，是提升教师理论水平、科研能力和教学技能的主要手段，是提高教学质量的有效途径。探讨地方高校推行学术休假制的必要性，提出地方高校推行学术休假的建议，对地方高校教师队伍建设具有重要的现实意义。在实施策略上，应注重4个方面：（1）明确参加学术休假的对象主要是教师和教学科研人员；（2）根据教师职业发展的阶段性确定学术休假的时间；（3）合理设置学术休假人员遴选条件，首先应考虑为工作满5年以上的青年教师提供学术休假，其次应考虑为高级职称教师提供学术休假；（4）明确学术休假期间的教师待遇，并加强对学术休假人员的管理。     

影子银行、地方政府债务及金融发展动态关系研究——基于省级面板VAR模型

基于2004—2017年中国省级面板数据,运用面板向量自回归(PVAR)模型,使用系统GMM估计、脉冲响应函数、方差分解以及格兰杰因果关系检验等方法分析了影子银行、地方政府债务及金融发展之间的动态关系.结果表明:影子银行、地方政府债务与金融发展水平三者之间存在动态耦合关系.在地方政府融资能力受到约束的情况下,影子银行为地方政府提供了多元的融资方式,在增加政府融资能力的同时提升了政府债务水平;而地方政府债务需求显著推动了影子银行规模的快速发展.同时,影子银行过度扩张危害了金融市场的健康发展,降低金融发展水平,继而使地方政府的融资渠道受到约束.但金融发展并不能有效约束影子银行规模,原因在于,政府融资需求是影子银行的主要动力,若不能控制地方政府的借贷行为则无法从源头解决问题.监管机构在去杠杆的过程中,应该综合考虑影子银行与地方政府债务、金融发展之间的动态关系,如此才能够实现预期的政策效果.     

The Value of a Statistical Life for Risk‐Averse and Risk‐Seeking Individuals

This article estimates the value of a statistical life (VSL) for Chile under the hedonic wage method while accounting for individual risk preferences. Two alternative measures of risk aversion are used. First, risk aversion is directly measured using survey measures of preferences over hypothetical gambles, and second, over observed individual behaviors that may proxy for risk preferences, such as smoking status, are used. I reconcile the results with a theoretical model of economic behavior that predicts how the wage‐risk tradeoff changes as risk aversion differs across individuals. The VSL estimates range between 0.61 and 8.68 million dollars. The results using smoking behavior as a proxy for risk attitudes are consistent with previous findings. However, directly measuring risk aversion corrects the wage‐risk tradeoff estimation bias in the opposite direction. The results are robust to other observed measures of risk aversion such as drinking behavior and stock investments. Results suggest that, consistent with the literature that connects smoking behavior with labor market outcomes, smoking status could be capturing poor health productivity effect in addition to purely risk preferences.     

地方党政主要领导职位空缺的现状、成因及对策

地方党政主要领导职位空缺是指在领导干部选任和调配过程中，由于诸多常规或非常规原因导致某一地区的党委或政府部门主要领导职位在较长时间内空缺，进而直接或间接影响地方党政工作的特殊现状，广泛存在于各级、各地党政部门。由于我国有关干部职位空缺的制度建设和管理规范尚不完善，地方党政主要领导职位空缺产生一些消极影响，主要表现为不利于地方党政机关运行，存在腐败风险，触发舆论风险等。在充分认识空缺危害性的基础上，深入分析造成职位空缺的干部调配因素、选任导向变革因素以及其他非常规因素等，从完善遴选机制、衔接制度、保障机制、舆论生态治理、干部教育等五个方面切实解决地方党政主要领导职位空缺带来的一系列问题。     

Welfare service privatization and opinions about service quality: The role of political ideology among local politicians and the public

In this article, we join the discussion about the potential consequences of welfare service privatization by examining the relationship between the privatization of welfare service delivery and public opinion about service quality in Sweden. Due to the politically polarized debate about welfare service privatization in Sweden, we also examine the extent to which individualsapos; ideological orientations influence this relationship in both local politicians and ordinary citizens. For local politicians, the results show that a higher municipal degree of privatization is generally associated with slightly lower levels of satisfaction overall with welfare services, although no such relationship exists for the public. Most importantly, however, the results indicate that political ideology constitutes an important moderator in the relationship between privatization and opinions about service quality. Local politicians and, to some extent, ordinary citizens who place themselves to the left on the ideological left–right scale tend to be less satisfied with services as the municipal degree of welfare service privatization increases. For local politicians who position themselves far to the right on the scale, the relationship between welfare service privatization and satisfaction is positive. These findings suggest that there is no clear-cut relationship between privatization and individualsapos; opinions about services; rather, this relationship depends on the ideological predispositions of local politicians and ordinary citizens.     

安大简《诗经》“侯六”“魏九”浅析

通过分析《毛诗·魏风》《唐风》诸篇的诗旨和安大简自身的特点,认为安大简《侯》《魏》两部分内并无“误置”现象。又从战国初期的历史背景出发,并结合诗旨、春秋战国时期的“用诗”特点,赞成安大简《魏》之所以抄写《毛诗·唐风》中的诗篇,当与战国时期魏国国力强盛、占有晋国故地相关。由于抄写《唐风》诗篇的部分被称为“魏”,因此,抄写《魏风》的部分就不能再称为“魏”,必须改题。从《毛诗》诸国风的命名逻辑看,“侯”极可能是地名。不过,若考虑到安大简的特点,“侯”为爵位也未尝不可。从安大简《侯》《魏》的特殊安排看,它无疑是一个改编本,其底本与《毛诗》应该非常接近。
