The great divergence on the Korean peninsula (1910–2020)

Before the 1960s, North Korea's GDP per capita was 30%–50% higher than South Korea's due to industrialisation during the 1930s. However, the governments of the two Koreas pursued different goals in the 1960s, which resulted in a reversal. The South Korean government made economic growth its ultimate goal. They did this by self-implementing, adjusting and instituting an export-oriented development strategy. On the other hand, the North Korean government tried to maximise its ability to survive by sacrificing gains from economies of scale. These differences brought about remarkable differences in economic performance. The gap between the two economies has continued to grow since the income level reversal in the 1970s.     

榆林市某羊场舍饲陕北白绒山羊羔羊死亡原因研究

本文旨在研究榆林市某羊场舍饲陕北白绒山羊羔羊的死亡情况及死亡原因,为治疗和预防羊场疾病提供理论依据。本文主要采用实地考察和访谈方式,了解羊场的饲喂、管理、配种以及产羔情况,并对羊场的消毒防疫、发病症状、病理变化和羔羊死亡数量做了详细记录。经统计分析得出羔羊死亡主要原因:繁殖障碍,哺乳失常,管理不当,肺炎和痢疾等。其中肺炎占死亡总数的13.9%,痢疾占死亡总数的68.7%,繁殖障碍死亡占死亡总数的5.2%;哺乳不当弱胎饥饿占死亡总数的7.8%;管理不善及其他原因占死亡总数的3.5%。主要防治措施:以预防为主,治疗为辅,标本兼治,加强饲养管理,全群注射三联四防苗,使羔羊死亡情况得以控制。

Power Relations and Social Mix in Metropolitan Neighbourhoods in North America and Europe: Moving Beyond Gentrification?

Research on spatial segregation has suggested that social mix may be a temporary phase in class displacement, where relations between different groups are at best divided or ‘tectonic’, for instance in England. Political and policy discourses, by contrast, tend to uncritically valorize social mix as a means to breaking up concentrations of poverty and providing neighbourhoods with a middle‐class voice. In the literature, little attention has been paid to power dynamics in socially mixed neighbourhoods and the implications this may have for understanding theory and policy. The five articles that make up this symposium address the ways in which social and ethnic groups interact in major cities in Europe and North America and, as the title suggests, this involves taking into account power relations, domination and negotiation between the different groups. There is a need to connect the experience of the deployment of power within neighbourhoods (and between them) with the discussions of power mechanisms at work in wider urban processes.     

A ‘new’ economic history of the Middle East and North Africa (MENA) region

This article argues that there is a need to develop a ‘new’ economic and social history of the Middle East and North Africa (MENA) region that is based on exploiting novel sources of data, including (a) primary papyrological sources from the medieval period, (b) primary sources at the region's local archives and European (colonial) archives, and (c) primary sources from the ancient (pre-Islamic) period. The proposed ‘new’ history of the MENA region must be inter-disciplinary for two reasons: (a) digitizing and employing these novel data sources in research requires the collaboration of social scientists, historians, archaeologists, anthropologists, demographers and papyrologists, as well as the co-operation of MENA-based scholars who have better access to MENA's local archives, and (b) even if these novel sources are digitized, data limitations are likely to impose a constraint on the reach of quantitative analysis and thus necessitate an inter-disciplinary methodology that combines quantitative evidence with historical analysis.     

海关支持综合保税区高水平开放高质量发展研究——以江苏省综合保税区为例

2019年1月12日,国务院印发了《关于促进综合保税区高水平开放高质量发展的若干意见》(国发〔2019〕3号,以下简称《若干意见》),推出21项政策措施加快推进制度创新、促进综合保税区(以下简称“综保区”)升级发展。文件出台后,各地综保区围绕“五大中心”的建设目标,在海关及其他相关职能部门的支持下,加强政策宣传,推动改革创新,强化考核评价,努力推动各项政策落地。为了更好地推进综保区高水平开放高质量发展,课题组对江苏省综保区发展情况开展全方位调研,并且以江苏省综保区为例,对当前制约综保区发展的原因,特别是影响《若干意见》实施效果的原因进行了深入分析,按照制度型开放的要求,从管理机制、发展目标、监管模式等角度提出合理建议,探索新时期海关支持综保区高水平开放高质量发展的路径。     

深度休闲对主观幸福感的影响研究——以苏南地区城市居民为例

深度休闲对优化苏南地区休闲产业建设,进一步提升居民休闲生活质量有重要影响。文章通过问卷调查的方式收集苏南地区城市居民深度休闲行为的数据,研究苏南地区城市居民深度休闲行为特征及深度休闲对主观幸福感的影响。结果发现:(1)苏南地区城市居民进行深度休闲活动的场所主要为户外;(2)闲暇时间不足是限制苏南地区城市居民进行深度休闲活动的主要因素;(3)苏南地区城市居民的深度休闲活动总体程度不高,愿意在深度休闲活动上投入大量时间和金钱的人更是少数;(4)苏南地区城市居民从事深度休闲活动产生的强烈认同感和坚持不懈的毅力对主观幸福感有着显著的积极影响。     

Fertility and the puzzle of female employment in the Middle East and North Africa

Female labour force participation rates across the Middle East and North Africa (MENA) region have remained low for over four decades even though, in the same period, women's education rapidly increased and fertility rates substantially decreased. This study provides a better understanding of this surprising phenomenon by testing whether the number of children affects the mother's labour supply (using twins at first birth as an instrumental variable.) Despite a strong first stage, it does not find statistically significant effects in the second stage, even in the combined sample of over 100,000 observations. This non‐result, however, does not rule out that fertility affects women's employment in these countries. But it rejects impacts larger than 0.09. Similar twin‐studies in the United States found effects between 0.12 and 0.31. The paper discusses the implications of this result in understanding the puzzle of female participation in MENA and in designing policies to increase women's employment.     

新冠肺炎对江苏省商贸流通业的影响与应对措施

2019年底、2020年初,一场猝不及防的新冠肺炎(NCP)病毒突袭我国的武汉地区。在地点上,武汉地区是京广线的重要节点城市,长江水运与京广铁路构成中国交通十字形的重要枢纽;在时间上,正逢中国传统春节,是中国节日经济的一个重要时期。病毒的“精准投放”并蔓延,在全国造成了严重后果,使全国上下纷纷动员进行应对,造成社会生活的暂停和群众生活的困难,对我国经济发展产生了重大影响,江苏商贸流通业也不例外地受到重创。江苏在中央的英明领导下进行了坚决的防治,商贸流通业也做了大量的工作,后期将继续做好止损增销工作。
