人口迁移与流动对我国各地区经济影响的实证分析

在对近十年来我国人口迁移和流动的时空演变格局进行初步考察的基础上,文章利用面板数据的变系数模型分别实证考察了人口迁移和流动对我国各地区(省域)经济的影响。结果发现:(1)我国各地区间人口迁移相对平稳,而人口流动在2000年以后呈现出持续快速增长的态势,且空间流向极不均衡;(2)人口的迁移和流动对中国整体经济来说是一个帕累托改进;(3)户籍制度对于发达地区起到了人才沙漏的作用;(4)对于中部的绝大部分地区以及西部的一些人口输出大省,伴随人口迁出而引起的人力资本流失对当地经济的负面影响开始凸显出来,人口流出虽然基本出现一个正面影响,但对本地经济发展的贡献并不如我们预想的那么明显。     

社会融合中的性别差异:流动人口工作搜寻时间的实证分析

文章以扩展传统的流动人口社会融合的静态研究视角,使用国家人口计生委2010年上半年流动人口动态监测调查数据,从男女农村流动人口工作搜寻时间的角度进一步比较农村流动人口融入流入地劳动力市场过程的性别差异及影响因素。文章采用持续时间模型,通过研究农村流动人口在流入地城市找工作所花费时间的影响因素,发现虽然在给定时间内,女性流动人口在流入地找到工作所花费的时间比男性要短,但女性找到高收入工作的概率要低于男性,而接受低收入工作的概率要大于男性,从而导致性别区隔的流动人口社会融入模式。     

水电工程移民收入测算模型构建及其应用研究

移民安置的目标已不再仅仅是按照水库蓄水的要求如期将淹没区居民和有关企、事业单位迁出库区,而且还要特别关注移民生产生活水平的恢复与提高。本文在构建水电工程移民收入测算理论模型以及第一手调查数据资料的基础上,建立符合实际经济社会发展状况的西南地区水电工程移民收入的测算模型,研究成果可以在西南地区水电工程移民收入的测算中推广。收入测算的结果也可以为移民政策的调整、改革及完善提供依据。     

城镇企业职工基本养老保险基金支付能力预测研究

随着人口老龄化进程的加剧。我国城镇企业职工基本养老保险基金收支出现了巨大缺口并呈现逐步扩大的趋势,导致基金支付能力持续下降。本文应用社会保障精算方法与技术,以社会养老保险现行政策为导向。引入2005年颁布的《国务院关于完善企业职工基本养老保险制度的决定》中新养老金计发办法的经济参数。构建城镇企业职工基本养老保险基金收入与基金支出测算模型,其中以2006年新政策实施年为时间界限。分别构建“老人”、2006年前退休的“中人”（“老中人”）、2006年后退休的“中人”（“新中人”）、“新人”四类群体的基本养老保险基金支出洲算模型。从而推导出城镇企业职工基本养老保险基金支付能力预测精算模型。以期对养老保险基金失衡风险和支竹能力危机进行及时预测。并为社会养老保险政策调整和制度完善提供量化依据。     

黑河流域人口承载力预测分析

人口承载力的研究对象是由若干个内部关系错综复杂、相互之间联系紧密的子系统所组成的“自然-经济-社会”复合巨系统,本文运用系统动力学建立复合模型仿真模拟预测黑河流域人口承载力状况．并建立黑河流域人口承载力的预警指标体系。复合模型预测数据显示,黑河流域人口承载力呈超载状态．而预警目标值Z=0．979〈1,说明该区没有实现持续发展,乃“磊、乙三个指标小于1,说明黑河流域生态环境和固定资产投资占比是影响黑河流域发展的主要因素。     

“一带一路”战略与中国对阿拉伯国家出口潜力分析

欧美的贸易保护主义盛起之时转变外贸地理方向成为我国外贸的一项重要工作,恰逢中国率先提出的“一带一路”战略规划了东亚开放的地区主义,处于“一带一路”交汇处的阿拉伯国家便成为了我们天然的经贸合作伙伴,从而对阿拉伯国家的外贸出口呈现出愈来愈强的重要性。本文基于贸易引力模型,通过中国对阿拉伯国家联盟中的20个国家2001年～2010年间的货物贸易出口数据,测算了同各国间的贸易潜力,基于中国与阿拉伯国家间存在的较大贸易潜力提出了几点结论与启示。     

上海自贸试验区负面清单转化为全国负面清单的路径和措施

目前,在中国(上海)自贸试验区的各项实施制度中,"负面清单"制度是其中重要的一项,也将是未来自贸区可复制、可推广的一项关键制度。对此,可借鉴《美国双边投资协议2012年范本》,将上海自贸试验区负面清单转化为全国负面清单,向全国推广。     

The embeddedness of organizational performance: Multiple Membership Multiple Classification Models for the analysis of multilevel networks

We present a Multiple Membership Multiple Classification (MMMC) model for analysing variation in the performance of organizational sub-units embedded in a multilevel network. The model postulates that the performance of organizational sub-units varies across network levels defined in terms of: (i) direct relations between organizational sub-units; (ii) relations between organizations containing the sub-units, and (iii) cross-level relations between sub-units and organizations. We demonstrate the empirical merits of the model in an analysis of inter-hospital patient mobility within a regional community of health care organizations. In the empirical case study we develop, organizational sub-units are departments of emergency medicine (EDs) located within hospitals (organizations). Networks within and across levels are delineated in terms of patient transfer relations between EDs (lower-level, emergency transfers), hospitals (higher-level, elective transfers), and between EDs and hospitals (cross-level, non-emergency transfers). Our main analytical objective is to examine the association of these interdependent and partially nested levels of action with variation in waiting time among EDs – one of the most commonly adopted and accepted measures of ED performance. We find evidence that variation in ED waiting time is associated with various components of the multilevel network in which the EDs are embedded. Before allowing for various characteristics of EDs and the hospitals in which they are located, we find, for the null models, that most of the network variation is at the hospital level. After adding these characteristics to the model, we find that hospital capacity and ED uncertainty are significantly associated with ED waiting time. We also find that the overall variation in ED waiting time is reduced to less than a half of its estimated value from the null models, and that a greater share of the residual network variation for these models is at the ED level and cross level, rather than the hospital level. This suggests that the covariates explain some of the network variation, and shift the relative share of residual variation away from hospital networks. We discuss further extensions to the model for more general analyses of multilevel network dependencies in variables of interest for the lower level nodes of these social structures.     

Assessing reporting patterns of child sexual abuse within the Catholic Church using discontinuities in model parameter timeseries

Prior to 2002, little was known about sexual abuse within the Catholic Church. After the Boston Globe broke the story about John Geoghan - a priest in the Boston Archdiocese who was accused of abusing numerous children, convicted of one count of indecent assault, and eventually murdered in prison - the Church had many questions to answer. To this end, the United States Conference of Catholic Bishops (USCCB) commissioned John Jay College of Criminal Justice to research the nature and scope, as well as the causes and context of child sexual abuse within the Catholic Church.This research analyzes the data from the John Jay studies using a new quantitative technique, capable of adjusting for distortions introduced by delays in abuse reporting. By isolating discontinuities in model parameter timeseries, we determine changes in reporting patterns occurred during the period 1982-1988. A posteriori to the analysis, we provide some possible explanations for the changes in abuse reporting associated with the change-point. While the scope of this paper is limited to presenting a new methodological approach within the frame of a particular case study, the techniques are more broadly applicable in settings where reporting lag is manifested.     

中国式财政分权的宏观经济绩效——基于限制型VAR模型的经验分析

本文从中央政府与地方政府行为角度构建了中国式分权与宏观经济绩效之间的关联框架,指出中国式分权体制下的地方政府竞争行为构成了中国经济增长以及周期性过热的主导力量。由于中国不同省份的自然历史、地理位置以及发展政策差异极大,即使是同样的分权程度也可能产生不同的经济绩效与激励效果,这也就使得面板数据模型回归结论对其设定形式非常敏感。因此,本文采用受限VAR模型来实证分析中国式财政分权对于经济增长率和通货膨胀率的作用效应,结论证实了本文的理论预期。
