智库、智库产品及智库竞争视角下的智库治理研究

建设中国特色新型智库需要加强智库治理。笔者结合智库内外部治理，提出智库治理的结构模型及影响因素。智库治理包括对智库产品、单一智库以及智库竞争的治理，这三类治理相互影响、相互强化。智库治理问题的本源性因素在于智库产品具有政策导向性、不完全性、难以精确衡量性，而条件性因素在于智库产业环境欠佳、智库人力资源缺乏。可以认为，智库治理应当从内外部两方面入手，围绕建立完善的智库产品及智库评价体系，建立完善公正、公开的多元市场竞争与需求机制，依据相关法律政策，明确智库及智库从业人员的权利、责任、义务、处罚等事项，而培养智库专业人才则应采取多样性、综合性的治理措施。总之，中国智库应当以习近平新时代中国特色社会主义思想为指导，加强对智库本身及智库产业、市场的治理，才能真正实现为中国的发展蓝图而赋予中国智库的新要求、新任务，真正有力促进国家治理体系和治理能力现代化建设。     

京津冀文化消费的影响因素与结构特征

在京津冀协同发展战略中,文化创意产业在取得初步发展成果的同时,还依旧面临着不少亟待解决的问题。采用问卷调查法实地走访采集区域居民文化消费数据,并进一步通过决策树算法进行数据挖掘,发现京津冀文化消费的影响因素及结构特征,据此提出打造区域共同文化品牌、保障居民收入持续平稳增长、针对青少年文化消费市场创新营销模式、培养其正确的文化价值观及文化创新能力等改进措施,从而优化推动京津冀文化消费市场协同发展的路径,打造互联互通、开放统一的区域文化消费市场,使区域居民文化消费需求成为促进文化产品供给的市场新动力。     

从造字到造形：汉字形体结构与书法艺术

汉字作为一种书写形体，笔画组合的丰富多样和间架结构的灵活多变，而使其“字形”成为复杂的美学构成，“书写”成为“书法”，并完成从造字到造形的转变。书法是汉字书写艺术，书法艺术深藏于汉字独特的形体结构之中。三位一体的整体架构、二维方块结体、平衡对称等汉字在形体构造上的诗性特征，既是人们对文字形体的一种审美预期，也是书法学家在书法创作时努力追求的美感。     

Sociolinguistics and modes of social class signalling: African perspectives

The paper evaluates spatial, behavioural, and material signalling of social class in African contexts, focusing on Kenya and Zambia. In particular, it draws on notions of mode of class signalling and intersectionality and a vignette of an interaction between urban‐based Western educated development agents and local participants in rural Kenya to illustrate how social class is implicated in interactions. The paper shows how significant features of class and dimensions of social inequality may be perceived intersectionally so that positionalities in class structures are negotiated in contexts of interaction, thus illustrating how structural conditions of class may be challenged and questioned. The paper concludes that sociolinguistics needs to identify the various ways in which the marginalized challenge social structures of inequality. Otherwise there is a risk that sociolinguistics will work to validate inequalities as permanent and fixed, and victims of unequal treatment as permanently condemned and never able to rise against oppressive social structures that tyrannize them.     

Family Characteristics and Mate Selection: Evidence From Computer‐Assisted Dating in Japan

Research on mate selection rarely considers singles' preferences for their future partners' family configurations and experiences. Using online dating records from a matchmaking agency in Japan, a society with a strong emphasis on family and kinship, we examine how singles' responses to date requests correspond to potential mates' family circumstances. Results showed that singles' preferences for potential partners' family characteristics stem from a concern about future obligations toward the partner's family and stereotypes associated with certain family traits. Singles are less likely to accept requests from those from large families, which are seen as traditional. Being from a large family, however, hampers individuals' dating chances more if they are firstborn and have no brothers, two conditions that make them the designated child to care for elderly parents. We also find that Japanese singles seek partners with more of the universally valued family traits rather than traits similar to their own.     

京津冀人口集聚对能源消费的影响

京津冀作为我国重要的人口集聚区,其区域发展面临严重的能源和环境问题。首先,基于STIRPAT模型构建京津冀面板数据模型,研究1990—2017年京津冀人口密度、经济增长、产业结构和环境规制对能源消费的影响。其次,采用SVAR模型通过脉冲响应函数和方差分解,研究京津冀人口密度变动对能源消费的作用机理和动态影响关系。结果显示,京津冀三地的人口密度、人均实际GDP与能源消费之间存在正向影响关系,其中河北省影响系数最大;北京和天津第三产业占比与能源消费之间存在反向影响关系,河北省第三产业占比对能源消费的影响不显著;北京和天津的环境规制对能源消费影响不显著,河北省环境规制对能源消费具有正向影响;京津冀地区和京冀两地人口密度变动对能源消费的影响在短期呈现负向效应,但是在中长期京津冀地区和三地人口密度变动对能源消费的影响均先上升然后缓慢下降,人口集聚具有集约用能效应。相对于能源消费自身影响而言,京津冀人口密度变动对能源消费的贡献相对较小,其影响效应有限。最后,对京津冀人口流动和能源消费一体化协同发展提出对策建议。     

煤炭上市公司资本结构与公司成长性研究

文章以沪深两市2015-2018年的煤炭上市企业数据为研究样本，研究煤炭企业资本结构和成长性之间的关系，采用因子分析法和线性回归的方法，从盈利能力，短期偿债能力，资产营运水平，发展能力四个方面反映企业成长性，最终得出盈利能力，短期偿债能力和资产营运水平和企业成长性之间存在着负相关的关系，这对促进煤炭企业构建合理资本结构，降低企业财务风险，保证企业经营目标有着实际意义。
