陕西省交通基础设施对经济增长的空间溢出效应

为了从外部性角度说明目前陕西省交通基础设施的建设和投资在地域上存在的问题，为陕西省交通基础设施建设方向提供理论帮助，基于陕西省2009~2017年间各市相关数据，在交通基础设施对经济增长效应研究的直接效应和溢出效应基础上，加入空间要素，构建生产函数和空间权重矩阵，通过自相关检验（莫兰指数）、LM检验和 Hausman检验，选取合适的空间面板计量模型对陕西省交通基础设施的经济溢出情况进行研究。研究认为，2009~2017年间陕西省交通基础设施对经济增长的溢出效应（显著）整体为负，但依然存在正溢出的局部地区，即以西安为首的经济聚集区（西安、宝鸡、咸阳）和榆林、延安联合的陕北经济聚集区，资源过于集中和两个高地之间缺乏互联互通是整体呈现负溢出的重要原因。在地域分配的量和质上应充分考虑交通基础设施的溢出效应，避免资源过度集中在西安，在两个经济高地之间打通一条经济要道，并重点扶持相对落后又有发展前景的城市可促使陕西经济发展由总体集聚向总体扩散转变。     

消费者网评使用习惯对网评效应的影响研究---网评奖励效果的中介和调节效应探索*

本文以网购旅游者为调查对象，分析其网评使用习惯及其在网评奖励效果作用下对网络评论效用发挥的影响。通过问卷调查和数据分析发现，网评使用习惯和网评奖励效果都对网评效应具有显著正向影响，但网评使用习惯的影响力大于网评奖励效果。同时，网评奖励效果对网评使用习惯与网评效应间的关系具有显著负向调节效应，它削弱了消费者网评使用习惯对网评效应的影响；但消费者的网评使用习惯不通过网站的网评奖励效果对网评效应发挥作用，网评奖励效果不具有中介作用。可见，在网评使用习惯、网评奖励效果和网评效应三者关系中，网评使用习惯是个独立的影响因素，它并不通过网评奖励效果发挥作用，并且由于网评奖励效果的加入，反而削弱了网评使用习惯对网评效应的影响。研究结论表明，对于网评奖励政策的效果，需要客观辩证地看待，不应一味夸大。     

Research on Marital Satisfaction and Stability in the 2010s: Challenging Conventional Wisdom

Although getting married is no longer a requirement for social acceptance, most people do marry in their lifetimes, and couples across the socioeconomic spectrum wish their marriages to be satisfying and long lasting. This review evaluates the past decade of research on the determinants of satisfaction and stability in marriage, concluding that the scholarship of the past 10 years has undermined three assumptions that were formerly accepted as conventional wisdom. First, research exploiting methods such as latent class growth analyses reveal that, for most couples, marital satisfaction does not decline over time but in fact remains relatively stable for long periods. Second, contrary to predictions of behavioral models of marriage, negative communication between spouses can be difficult to change, does not necessarily lead to more satisfying relationships when it is changed, and does not always predict distress in the first place. Third, dyadic processes that are reliably adaptive for middle-class and more affluent couples may operate differently in lower income couples, suggesting that influential models of marriage may not generalize to couples living in diverse environments. Thus, the accumulated research of the past 10 years indicates that the tasks of understanding and promoting marital satisfaction and stability are more complex than we appreciated at the start of the decade, raising important questions that beg to be answered in the years ahead.     

Couple-Level Patterns of Disclosure Process Beliefs and Their Association with Marital Satisfaction

Abstract

Grounded in symbolic interaction theory, we used latent class analysis (LCA) to investigate the preexisting patterns of belief surrounding the disclosure process in married relationships. With a sample of 131 heterosexual married dyads from the U.S., we found four classes: two classes represented similarity of spouses’ beliefs (Both High Beliefs and Neither High Beliefs), and two classes represented dissimilarity of spouses’ beliefs (where only the wife endorsed high beliefs, Wife High Beliefs, and where only the husband did, Husband High Beliefs). Husbands’ satisfaction was positively associated with membership in the Both High Beliefs class. An interaction between spouses’ satisfaction was found: the impact of wives’ satisfaction on class membership is dependent on husbands’ satisfaction. Implications for research and practice are discussed.     

Heterogeneous treatment effects on Children's cognitive/non-cognitive skills: A reevaluation of an influential early childhood intervention

The 1962–67 High/Scope Perry Preschool Program, a well-known experimental early childhood intervention study that provided quality preschool education to disadvantaged children, has been shown to have had positive impacts on early child development and on a variety of adulthood outcomes. However, most previous analyses have only examined average treatment effects across all program participants without exploring possible effect heterogeneity by children's background characteristics. We investigated this question by first using the 1964–65 Current Population Survey data in combination with the Perry data to construct a scale of child socioeconomic status based on the estimated propensity for inclusion in the Perry program, then analyzing effect heterogeneity within the Perry sample by strata of our socioeconomic scale. We found that the treatment effects of enrollment in the Perry preschool on cognitive and non-cognitive skills were much larger and more persistent among the most disadvantaged children than among others in the Perry program. Furthermore, among the most disadvantaged children, the treatment (i.e., preschool enrollment) affects later outcomes through a reinforcement mechanism of skill development (i.e., early cognitive gain leads to a non-cognitive gain, which in turn leads to later cognitive gain) and a sequential improvement of cognitive skills over time. These findings have important implications for the evaluation of policy interventions in early child development using experimental data.     

儒、商互动与晚明郎署文学权力之下降

奢靡世风之下的儒、商互动,建立在士人逐利、商贾求名基础之上,导致士商相混,界限模糊。这一方面促使郎署文人自觉不自觉地调整、改易着其写作风貌,以前多适用于上流社会的一些应用文体,很大程度上因之走向商贾、市井之家,逐渐普泛化、世俗化。另一方面,它又是“性灵”说的催生剂。同时,还使得一些郎署文人关注通俗文学,自觉参与到小说、戏曲等通俗文学样式的创作、刊刻、批评与传播过程中。这从内外两个层面,对郎署文学形成很大冲撞,致使其文学权力下降。从某种意义上说,这标志着晚明文学开始由以传统诗文为主的雅文学,逐渐向以小说、戏曲为重心的通俗文学转型。     

通过科学立法促进民族交往交流交融的法理探讨

在中华民族“多元一体”背景下，加强各民族交往交流交融，是铸牢中华民族共同体意识的必然要求。而通过科学立法建立完备的法律规范体系，则是运用法治思维和法治方式，促进各民族交往交流交融的根本前提。当前我国的民族法律规范体系虽已基本建成，但仍存在一些法律原则的表达不够严谨、法律概念的界定不够准确、法律规则的内容不够明晰和完整、规范体系的结构不够完备和和谐等缺陷和不足，难以满足在政治、经济、文化、社会和生态建设中通过法治方式有效协调民族关系，促进各民族交往交流交融的需要。这就要求立法者应遵循《立法法》确定的科学立法的形式合理性和实质合理性的要求，妥善处理法律规范体系与现实需要的适应性和可执行性，由此才能为通过法治促进各民族交往交流交融奠定坚实的制度基础。从科学立法与依法立法、民主立法的关系来看，遵循依法立法，是保障法的形式合理性的前提；坚持民主立法，则是保障法的实质合理性的根基。为提升立法的科学品质，必须健全违宪审查机制、协商民主机制和立法理论形成机制，确保依法立法、民主立法原则的有效落实。     

合格境外机构投资者与企业绩效

选取2007—2016年的A股上市公司作为研究样本，考察了合格境外机构投资者持股对企业绩效的影响。研究发现，合格境外机构投资者持股比例与企业绩效显著正相关，即能有效提高企业绩效。还进一步考察了终极控制人性质对合格境外机构投资者与企业绩效之间关系的影响，经验证据表明，与民营企业相比，合格境外机构投资者对国有企业的绩效影响更加显著。     

Does community social embeddedness promote generalized trust? An experimental test of the spillover effect

Despite the theoretical relevance attributed to the spillover effect, little empirical research has focused on testing its causal validity. Addressing this gap in the literature, I propose a novel experimental design to test if the overall density of social links in a community promotes trustworthy and trusting behaviors with absolute strangers. Controlling for social integration (i.e. the individual number of social connections), I found that density fosters higher levels of trust. In particular, results show that people in denser communities are more likely to trust their unknown fellow citizens, encouraging isolated subjects to engage with strangers. However, evidence did not support the idea that community social embeddedness causes an increase of trustworthiness, indicating that the spillover effect works only with respect to trust.     

北洋政府时期的劳动立法问题探析

中国的劳动立法开始于20世纪20年代的北洋政府时期。这一时期，迫于工人运动的压力，政府相继出台了工厂法、矿山交通劳动法、工会组织法、劳工福利法等方面的法规。这些劳动立法，从理论和制度层面上来讲是一大进步。然而，北洋政府制定劳动法规的根本目的是为了抑制工人反抗，调和劳资矛盾，维护统治秩序，并未想从根本上改变劳工的劳动和生活状况及其社会地位。因此，北洋政府时期劳动立法的实施成效欠佳，其制度的建设意义远大于对工人保障的实际意义。
