异质性产业集聚对城市创新发展能力的影响

城市创新圈是创新要素的高聚集、高密度的创新系统。本研究尝试将产业集聚和数字经济同时纳入城市创新发展能力的分析框架,基于中国2005—2020年262个地级市面板数据,通过理论分析与GMM模型实证检验相结合,讨论产业集聚对城市创新发展能力的影响。主要结论如下：产业集聚均对城市创新有着正向的促进作用,并且促进效果顺序是制造业集聚大于协同集聚,生产性服务业集聚排在最后。异质性检验表明,在产业集聚对城市创新的影响中,南方地区城市均表现显著的促进作用,北方地区城市则只有制造业集聚对城市创新存在显著的促进作用。数字经济只在制造业集聚对城市创新的促进作用中发挥正向调节作用,在生产性服务业集聚和协同集聚对城市创新的影响中均发挥出负向调节作用。     

论城市房屋拆迁中的法律问题

在当前城市拆迁过程中,由于诸多复杂因素,引起了许多纠纷与矛盾,有的甚至非常严重。从法律关系的角度来看,这其中涉及到复杂法律关系的处理,包括行政法律关系和民事法律关系。这两种法律关系处理的好坏,直接关系到城市拆迁活动的顺利进行,也关系到拆迁法律关系中各方当事人利益的保护问题。同时,现有的城市拆迁法律制度的不完善,在一定程度上给这类问题的解决带来了不便。本文拟从城市拆迁中的法律关系、拆迁法律制度中存在的问题和城市拆迁中行政机关的角色定位等方面进行分析和探讨,以期更好地认识和解决拆迁过程中产生的问题。

论政治文明的文化选择

文化即人化,它是人类所创造的精神成果和物质成果的总和;文明是文化的结晶,是文化主体对人类文化中野蛮性、愚昧性不断扬弃的结果,是人类有目的、有选择地过滤人类文化、形成合理文化内核的过程。中国当前的政治文明建设,需要走出“精华”和“糟粕”的简单二分的误区,用外来文化中国化、传统文化现代化,来开辟中国文化发展之路。弱化暴力色彩,强化仁政效应,构建中国特色的政治文明。     

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.

     

Female fertility history and mid-late-life health: Findings from China

China’s middle-aged and older women suffer from poorer health than men. Using national baseline data from the China Health and Retirement Longitudinal Study (CHARLS), a survey conducted from 2011 to 2012, this article applies logistic models to investigate the association between female fertility history (parity, early childbearing, late childbearing) and middle-aged and late-life health. We find that parity is related to the mid-late-life health of women. Women with four children or more are more likely to suffer from activities of daily living (ADL) impairment and poorer self-rated health than those with one to three children. Early childbearing is associated with ADL impairment; however, the correlation is mediated by socioeconomic status. Early childbearing is related to self-rated health in later life by an indirect-only mediation effect via educational attainment and personal income.     

Minimum 2-distance coloring of planar graphs and channel assignment

A 2-distance k-coloring of a graph G is a proper k-coloring such that any two vertices at distance two get different colors. \(\chi _{2}(G)\)=min{k|G has a 2-distance k-coloring}. Wegner conjectured that for each planar graph G with maximum degree \(\Delta \), \(\chi _2(G) \le 7\) if \(\Delta \le 3\), \(\chi _2(G) \le \Delta +5\) if \(4\le \Delta \le 7\) and \(\chi _2(G) \le \lfloor \frac{3\Delta }{2}\rfloor +1\) if \(\Delta \ge 8\). In this paper, we prove that: (1) If G is a planar graph with maximum degree \(\Delta \le 5\), then \(\chi _{2}(G)\le 20\); (2) If G is a planar graph with maximum degree \(\Delta \ge 6\), then \(\chi _{2}(G)\le 5\Delta -7\).
