资本结构治理效应:中国上市公司的实证研究

资本结构影响公司治理的结果最终会体现在公司绩效的变化上。本文通过对1992-2004年间我国上市公司资本结构影响公司绩效的实证分析发现:资产主营业务净利润率、经营费用率和资产利用率三个指标比股票价值能更好地解释资本结构对公司绩效的影响;国家股比例对公司绩效的负向影响越来越不显著;法人股比例和负债融资比例对公司绩效有不显著的正向影响等。这些结论表明,完善资本结构是完善我国上市公司治理结构从而提高公司绩效的重要途径之一。

南充市城区已婚育龄妇女二孩生育意愿研究

2018年4—5月在四川省南充市城区采用便利抽样,以已婚且未育或已育一个小孩的育龄妇女为研究对象,采用自制匿名问卷,以面对面的形式收集资料,了解实施全面二孩政策后南充市育龄妇女的生育意愿,为南充市的人口研究提供参考依据。在213名调查对象中,56人(26.3%)有二孩生育意愿,140人(65.7%)无二孩生育意愿,17人(8.0%)不确定是否生育二孩。南充市被调查者的理想子女个数均值为1.46,意愿子女个数均值为1.27。不同文化程度(χ2=7.512)、配偶月收入(χ2=12.641)、理想子女数(χ2=66.401)、一孩性别(χ2=5.441)的育龄妇女间二孩生育意愿差异有统计学意义(P<0.05)。Logistic回归分析显示,第一个孩子性别为女孩(OR=2.641,P=0.021)、丈夫月收入越高(OR=1.761,P=0.028)、理想子女数多于1个(OR=29.040,P<0.001)的育龄妇女更有意愿生育二孩。南充市城区二孩生育意愿处于较低水平,经济收入、理想子女数、一孩性别会影响育龄妇女的二孩生育意愿。全面二孩政策对于促进育龄妇女生育二孩的效应有限,应当建立相关的配套政策,以促进全面二孩政策的实施。     

电子商务对区域城市发展辐射力的评价研究

电子商务对于现代区域城市的发展具有重要作用,从产业、技术、社会和经济四个辐射效应构建出电子商务对福建省九个地市发展辐射力的综合评价指标体系,运用熵权法和模糊综合评价法对2016年福建省九个地市电子商务辐射力进行测度与实证分析.结果表明:福建省电子商务辐射效应大小依次是产业、技术、经济和社会效应,区域辐射力强弱状态呈现出明显的三个梯队.研究结果可为电子商务在福建省区域城市发展中的产业合理布局与持续全面健康发展提供决策支持.     

社会嵌入与社区集体经济发展——来自中国城市社区的经验证据

当前中国城市社区集体经济的传统发展模式越来越难以适应新形势的要求,很多城市相继建立了以社区股份合作公司为主要形式的市场化运作模式。然而,社区集体经济发展不仅是经济的发展,更是社区与社会的发展,社区集体经济的市场化无疑偏离了社区发展的轨道,面临着社会脱嵌的风险。具体来看,社区集体经济的社会脱嵌表现为行动脱嵌、规则脱嵌和资源脱嵌,浙江杭州高沙社区的集体经济发展态势为此提供了经验证据。社区集体经济市场化导致的社会风险需要引起地方政府的关注与重视,地方政府应实施积极的干预政策以纠正社区集体经济发展的方向。     

实施乡村振兴战略要防止的几种倾向

乡村振兴战略是要服务于中国建设社会主义现代化强国的目标,是要为建设中国社会主义现代化强国提供稳定的农村基础。 在不同阶段,乡村振兴战略的任务是不同的,尤其是 2035 年之前和2035—2050 年的乡村振兴战略应该是差异极大的。 2035—2050 年的目标是全面乡村振兴,2035 年之前则是为乡村全面振兴打基础的阶段。 没有中国现代化的基本实现,就没有全面振兴乡村的物质基础。乡村振兴战略必须分阶段实施。 当前学界、政策部门、地方实践部门在解读乡村振兴战略时普遍误解了乡村振兴战略的实施阶段性特征,有急于求成的倾向。     

Assessing Risk‐Based Upper Limits of Melamine Migration from Food Containers

Melamine contamination of food has become a major food safety issue because of incidents of infant disease caused by exposure to this chemical. This study was aimed at establishing a safety limit in Taiwan for the degree of melamine migration from food containers. Health risk assessment was performed for three exposure groups (preschool children, individuals who dine out, and elderly residents of nursing homes). Selected values of tolerable daily intake (TDI) for melamine were used to calculate the reference migration concentration limit (RMCL) or reference specific migration limit (RSML) for melamine food containers. The only existing values of these limits for international standards today are 1.2 mg/L (0.2 mg/dm²) in China and 30 mg/L (5 mg/dm²) in the European Union. The factors used in the calculations included the specific surface area of food containers, daily food consumption rate, body weight, TDI, and the percentile of the population protected at a given migration concentration limit (MCL). The results indicate that children are indeed at higher risk of melamine exposure at toxic levels than are other groups and that the 95th percentile of MCL (specific surface area = 5) for children aged 1–6 years should be the RMCL (0.07 mg/dm²) for protecting the sensitive and general population.     

Is Tattooing a Risk Factor for Adolescents’ Criminal Behavior? Empirical Evidence from an Administrative Data Set of Juvenile Detainees in Taiwan

Juvenile crime affects not only the victims of the crime but also the delinquents’ future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents’ criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide. A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery. From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents’ high probability of committing crimes.

Anger Expression and Persistence in Young Children

This study investigated anger expression during toy removal (TR) in 92 young Chinese children, two to five years of age, and its relations to their persistence in responding to obstacles during two challenging tasks with highly desirable goals [TR and locked box (LB)] and one challenging task with a less desirable goal [impossible perfect circles (IPC)]. Anger expression during TR was positively associated with persistence during TR and LB but not during IPC. The results highlighted the positive effects of anger in the development of persistence.
