金融结构对产业结构影响的时变特征研究——基于SUR和TVPSS模型的实证检验

金融结构与产业结构的关系一直是学术界的研究热点.文章利用中国1998—2017年的年度数据,构建似不相关回归模型从金融结构规模、效率及深化的角度分析金融结构对产业结构合理化和高级化的影响,建立时变参数状态空间模型描绘了金融结构对产业结构合理化和高级化的动态冲击.实证分析结果表明:金融结构规模提高产业结构合理化水平,促进了产业结构高级化;金融结构效率提高产业结构合理化水平,抑制了产业结构高级化;金融结构深化降低产业结构合理化水平,促进了产业结构高级化.金融结构规模、金融结构效率及金融结构深化对产业结构合理化和高级化的冲击均呈现出时变特征;金融结构对产业结构合理化的影响滞后于其对产业结构高级化的影响.金融结构对产业结构的冲击波幅呈现出前期波动大、后期较为平缓的状态,部分金融结构变量对产业结构的动态冲击呈现出"长尾"现象.当前的中国金融结构已经不适合当前的产业结构,需调整金融结构,以提升产业结构合理化水平和高级化水平.     

东亚文化背景下青少年设计创造力培养的创新

文化是人类活动的深层心理结构,东亚文化是东亚地区青少年设计创造力培养的重要影响因素。东亚文化以儒家思想为核心,有其鲜明特点,深深影响着东亚教育观、教师观、家庭观以及价值观。文化创新是青少年设计创造力培养的推动剂,加强东亚文化创新建设,应采用树立鼓励创造的教育观、培养热爱创新教育的教师、营造非权威的家庭环境、内化青少年创新价值观等创新策略,有效促进青少年设计创造力的发展。     

Deciphering blog users: young adults’ personalities,motivations, and perceived importance of blog features

The present study examines the cyberpsychology of blog readership as well as the digital content preferences of the Millennial generation by examining the links between college students’ personality traits, motivations to read blogs, and preferred blog features. Results indicate that personality influences motivations for reading blogs, which in turn helps predict perceived importance of blog characteristics. Notably, extraversion and neuroticism were related to reading blogs for social interaction; extraversion negatively predicted use of blogs to meet identity needs; openness was related to blog reading for entertainment purposes; and conscientiousness was positively associated with information seeking via blogs. Additionally, motivations for blog readership as explanatory mechanisms for the relationships found between personality traits and perceived importance of blog features are discussed.     

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.     

Parametrizing the Kepler exoplanet period-radius distribution with the bivariate normal inverse Gaussian distribution

This paper presents a simple and robust method for obtaining a comprehensive understanding of the joint period and radius distribution in Kepler exoplanets. The proposed method is based on particle swarm optimization and bivariate Normal Inverse Gaussian distribution. Furthermore, in the construction of the probability density function, this study selects planet-host stars with the GK-type. The injecting approach is also employed to solve the survey completeness of sample. The resulting occurrence rate of Earth analogs is 0.025 with a 95% bootstrap confidence interval between 0.023 and 0.032.     

A phenomenological case study on immigrant workers' gambling addiction in Korea

This study explores the experiences that have led some of Korea's immigrant workers into gambling addiction and examines possible social welfare services that could support treatment. Immigrant workers' gambling experience as aliens in Korea was analyzed through the methodology of a phenomenological case study. The participants, who voluntarily consented to the study, were five immigrant workers addicted to gambling. Data were collected through one‐on‐one, in‐depth interviews over 6 months, starting in July 2018. The essential themes that emerged in the interviews were “changing strategies for survival,” “forgetting oneself without any sense of responsibility or shame,” “gambling as routine daily life,” “obsession with making a fortune in one go,” and “no home to return to.” Based on its results, this study makes suggestions for the prevention of gambling addiction in immigrant workers. Further, future research needs to be broadened to analyze nationwide cases of immigrant workers with more diverse demographic backgrounds.     

Optimal scheduling replacement policies for a system with multiple random works

From the economical viewpoint in reliability theory, this paper addresses a scheduling replacement problem for a single operating system which works at random times for multiple jobs. The system is subject to stochastic failure which results the imperfect maintenance activity based on some random failure mechanism: minimal repair due to type-I (repairable) failure, or corrective replacement due to type-II (non-repairable) failure. Three scheduling models for the system with multiple jobs are considered: a single work, N tandem works, and N parallel works. To control the deterioration process, the preventive replacement is planned to undergo at a scheduling time T or the job's completion time of for each model. The objective is to determine the optimal scheduling parameters (T^* or N^*) that minimizes the mean cost rate function in a finite time horizon for each model. A numerical example is provided to illustrate the proposed analytical model. Because the framework and analysis are general, the proposed models extend several existing results.

高技术复杂度中间品进口会加剧制造业中间品进口依赖吗?

本文在测度制造业和服务业中间品进口技术复杂度的基础上,剖析了中间品进口技术复杂度对中间品进口依赖的作用机制及其作用渠道,并进一步分析了中间品进口技术复杂度对经济量增和质增的作用机制。得到的结论主要有:一是高技术复杂度中间品进口会加剧一国的中间品进口依赖,该结论在多维度检验中均稳健成立,这一机制不仅有助于高技术中间品先发企业成为制衡全球价值链的链主,还容易导致高技术复杂度中间品后发企业成为全球价值链的被俘获者和尾随者;二是高技术复杂度中间品进口通过抑制制造业的资本积累和科研人员规模扩大来加剧高技术复杂度中间品进口国的中间品进口依赖,中国的制造业和服务业中间品进口技术复杂度远高于自身经济发展水平,这使得中国承受的中间品进口依赖压力可能远高于其他国家;三是高技术复杂度中间品进口是经济量增和质增的重要推动力量,促进经济量增和质增战略与降低中间品进口依赖战略之间存在潜在冲突,这一潜在冲突也证实了中国当前以国内大循环为主体发展战略的科学性和正确性。
