基于最新统计分类标准的数字经济发展水平测度

随着信息技术的发展,数字经济已经成为经济增长的"新引擎"。但由于缺乏权威的产业统计分类标准,学者们一直面临"数字经济研究缺乏数字依据"的尴尬境地。文章基于国家统计局公布并实施的《数字经济及其核心产业统计分类(2021)》中的分类标准,对各省份统计年鉴的数据进行重新整理,利用熵权法构建数字经济发展指数,测度了我国30个省份的数字经济发展水平,分析了各省份数字经济发展的差异以及时空特征。研究发现,2009—2019年我国数字经济产业发展迅猛,各项子产业都取得了长足的进步。相比较而言,数字要素驱动业发展速度略低于其他三个子产业;数字经济发展存在着明显的区域不平衡。东中部地区的数字经济发展状况明显优于西部地区,南方优于北方,而且区域不平衡有持续扩大趋势。     

Vocational Status,Hukou and Housing Migrants in the New Century: Evidence from a Multi-city Study of Housing Inequality

In the 1960s and 1970s, the countries of Central and Eastern Europe and the Soviet Union experienced an unanticipated stagnation in the process of mortality reduction that was accelerating in the west. This was followed by even starker fluctuations and overall declines in life expectancy during the 1980s and 1990s. We identify statistically the extent to which, since the 1990s, the countries of the post-communist region have converged as a group towards other regional or cross-regional geopolitical blocks, or whether there are now multiple steady-states (‘convergence clubs’) emerging among these countries. We apply a complex convergence club methodology, including a recursive analysis, to data on 30 OECD countries (including 11 post-communist countries) drawn from the Human Mortality Database and spanning the period 1959–2010. We find that, rather than converging uniformly on western life expectancy levels, the post-communist countries have diverged into multiple clubs, with the lowest seemingly stuck in low-level equilibria, while the best performers (e.g. Czech Republic) show signs of catching-up with the leading OECD countries. As the post-communist period has progressed, the group of transition countries themselves has become more heterogeneous and it is noticeable that distinctive gender and age patterns have emerged. We are the first to employ an empirical convergence club methodology to help understand the complex long-run patterns of life expectancy within the post-communist region, one of very few papers to situate such an analysis in the context of the OECD countries, and one of relatively few to interpret the dynamics over the long-term.     

Household Assets,the Role of Government Assistance,and Depression Among Low-Income Families in Shanghai

As China’s economy is rapidly changing from a planned to a capitalist economy, many families find themselves financially struggling. In some cases, conflicting values and attitudes may contribute to mental health challenges such as depression that would lead to further feelings of helplessness and immobilization. Using a random sample of 1006 low-income households from Pudong District of Shanghai, China, this study aims to examine the relationships between household assets, beliefs about government as the primary way to improve economic circumstances and self-reported depressive symptoms. In addition, this study investigates the mediation effects of beliefs that government is the best change agent for improved life circumstances on the relationship between household assets and depression. We found those who indicated that government was the main means for attaining a better life had significantly higher depression levels whereas higher numbers of household assets were associated with lower depression levels. We also found that viewing government as the most important change agent only partially mediated the relationship between household assets and depression (p?<?.001). Findings from this study support anti-poverty policies and social work related practice initiatives aimed at assisting low income families in China, in particular the need to address psychological as well as economic needs.

     

文化转向:大学毕业生城市流动的新逻辑

西方城市人口增长的文献在过去几十年间经历了"文化转向":工作就业等经济因素让位于文化休闲等消费因素成为人口流动的主要吸引力。城市人口流动的"文化转向"在中国同样明显,尤其表现在大学毕业生群体当中。城市在大学毕业生眼中已经不再是简单的工作地点。城市是学习机器,是娱乐机器,越来越多的大学毕业生在城市流动选择中追求价值实现,表达自我,体验生活和分享梦想。青年大学毕业生是城市人口流动最活跃的群体。他们的城市流动目的地选择直接影响到城市社会、文化经济的发展。     

Risk Analysis: Celebrating the Accomplishments and Embracing Ongoing Challenges

As part of the celebration of the 40th anniversary of the Society for Risk Analysis and Risk Analysis: An International Journal, this essay reviews the 10 most important accomplishments of risk analysis from 1980 to 2010, outlines major accomplishments in three major categories from 2011 to 2019, discusses how editors circulate authors’ accomplishments, and proposes 10 major risk-related challenges for 2020–2030. Authors conclude that the next decade will severely test the field of risk analysis.     

广西沿边"适应-竞争-合作"式 城镇演化模式研究 ——以凭祥、东兴为例

新时代不充分不平衡发展问题突出，加大力度支持边疆民族地区加快发展的要求迫在眉睫。广西沿边民族地区发展总体滞后，城镇发展模式趋同；东兴和凭祥在沿边城镇发展模式趋同的情况下，在“适应-竞争-合作”式城镇演化过程中，充分利用国家政策、发挥比较优势、培育优势特色产业、深化内外合作，实现了城镇经济的跨越式发展。本文以生物学“趋同进化”理论为基础，结合新发展理念和东兴、凭祥的发展经验建议：广西沿边民族地区采取“适应-竞争-合作”式城镇发展模式，以创新增强各城镇内生动力，以互补合作促进协调发展，以绿色发展道路助推城镇发展的可持续性，以加强内外市场的联动性来深化城镇开放、合作式发展，以“省-市-县”、“县-镇-村”的互联互通推进共享发展。

WTO协议在我国法院的适用

加入WTO给我们提供了加速发展的机遇,同时也给我们提出了巨大的挑战。为了最大限度地利用好WTO这把“双刃剑”,我们必须首先解决如何执行和实施WTO规则体系的问题。本文拟对WTO协议在国内法院的直接适用问题进行探讨,通过对WTO协议理论和各成员方有关法律和司法实践的分析得出这样一个结论,即WTO协议在我国法院不具有直接效力,还不能得到直接适用。
