The role of technological catch up and domestic market growth in the genesis of emerging country based multinationals

The paper presents a model that evaluates how upgraded technological capabilities of emerging country based multinationals (EMNCs) and an increase in the domestic market size of large emerging countries affect value chain location choices and the competitiveness of emerging country based firms versus advanced country based ones. The model shows that, even without possessing a competitive advantage in terms of technology and/or brands, EMNCs from large or rapidly technologically advancing countries can become dominant players in the global system. The model highlights the central role of firm level technological intensity and product differentiation in determining the location of value chain activities as well as defining organisational boundaries. Empirical analysis of the location choices of the world's top multinationals from large advanced and emerging countries in 2010 supports the model's predictions.     

基于循环经济深入发展的减物质化多重因素分解

从减物质化的内涵出发,阐述减物质化是循环经济深入发展和维持生态经济大系统均衡和功能的关键。基于拉斯拜尔指数和完全分解模型,对减物质化进行多重因素分解,研究物质强度、经济结构和经济规模对物质减量的影响,分析物质消耗的反弹效应与减量效应,以1985年～2006年我国能源消耗为例进行实证研究。结果表明：经济规模扩张是驱动我国能源消耗的主导因素,21年间共计驱动能源消耗23.6×10⁸t标煤。经济结构的不尽合理增加能源消耗1.82×10⁸t标煤,经济规模效应与结构效应的叠加使我国能源消费量呈逐年递增趋势。能源强度的减量效应共节约能源9.67×10⁸t标煤,但强度因素的物质减量效应被经济规模扩张效应的增加所抵消,能源消耗的反弹效应明显。因此,在通过物质强度指标调控物质流动路径和方式的同时,应注重经济结构良性调整产生的减量效应,进而减小与抑制反弹效应,通过物质绝对减量指标测度循环经济的发展水平,实现经济发展与生态环境的良性互动。     

知识经济时代服务业发展的新趋势

从20世纪90年代开始,在经济全球化和信息化浪潮推动下,全球产业结构开始从“工业型经济”向“服务型经济”转型;从21世纪开始,随着信息技术、网络技术、数字技术等新兴技术的快速发展,整个服务业中知识化、专业化趋势不断加强,全球范围内的服务业发展又出现了一次新的转型,即从传统型服务经济向知识密集型服务经济转型.在知识、技术和全球化力量的推动下,服务业表现出了新的发展趋势.     

对我国土地使用权制度的思考

近几年来,随着人们财富的增加,社会财富为保值增值,到处寻求投资渠道,而土地限期使用制度则严重限制了投资领域,并促进工商实业投资行为短期化,从而导致经济社会发展躁动不安,社会资源难以沉淀为永久性社会财富。因此,必须改革和调整土地生产关系,逐步征收集体土地,全面推行土地国有,推行土地永久使用制度,从而调节社会资金流向,平抑社会投机,给社会实业提供一个长期稳定的持续发展平台,以实现经济社会的稳定、健康、持续、和谐发展。

Innovations in creative education for tertiary sector in Australia: present and future challenges

Abstract

Recent significant changes in technology such as Artificial Intelligence (AI) and big data analysis have a wide impact in many areas of human societies, not least in education. Advances in efficiency of new technologies, with impacts in renewable energy and transport affected by environmental concerns and climate change mitigation, demand a reassessment and adjustment of the industrial structure of the economy. Technological advances enhancing creativity and analytical skills mean people must learn and adapt to a fast-changing economic environment. This paper present some key changes in Australian educational areas in recent years that are important and relevant to the subject of education innovation and philosophy to achieve outcomes in training and sustainable economic development, as anticipated by the community and government. Education courses and curricula in many countries have been transformed by technological advance. It is the swift incorporation of new technologies that best prepares students for the dynamics of economic and social change. Even though technological responsiveness is not a new phenomenon, it is established that the teaching methods found to be most successful include complementary and supplemental courses producing multi-skilled and creative graduates. These courses are delivered with significant emphasis upon self-development skills and are less focused upon traditional content. A move toward horizontal focus and a student-centric balance is the current trend, displacing vertical over-specialisation of learning. Yet, the central role of educator is seen as still appropriate and necessary where the aim is to equip graduates with creative and adaptive skills.

Do universal social and emotional learning programs for secondary school students enhance the competencies they address? A systematic review

While universal school‐based social and emotional learning (SEL) programs claim to target various SEL competencies, earlier reviews have not provided a clear overview of the competencies in question. We therefore wished to identify the competencies targeted in SEL programs for secondary school students. We also aimed to examine the effects of these programs on SEL competencies and psychosocial health. The specific SEL competencies directly addressed in the programs' primary learning targets were identified based on the Collaborative for Academic, Social and Emotional Learning (CASEL) framework for SEL. Five bibliographic databases (PubMed, PsychINFO, Education Resources Information Center (ERIC), Applied Science Premier (ASP), and Web of Science) were searched for relevant research papers published between 2014 and 2018. We included 40 studies that investigated 32 programs focusing on two or more SEL competencies. While most programs targeted four or five of the SEL competencies, many of the included studies did not measure the programs' effects on all the competencies targeted. Our results showed that the SEL programs had substantial effects on the SEL competencies they addressed and on psychosocial health. Although the programs focused predominantly on self‐management skills and relationship skills, the largest summary effects were found for self‐awareness and social awareness.     

生态旅游扶贫对农民收入增长的实证研究——以广西壮族自治区巴马瑶族自治县为例

生态旅游扶贫是自然资源禀赋但经济社会发展落后地区,特别是西部民族贫困地区精准扶贫的重要举措,而农民收入持续增加是精准脱贫的硬性考核指标。论文以广西壮族自治区巴马瑶族自治县为例,基于生态旅游发展和农民收入的实际情况,利用SPSS统计软件对巴马生态旅游发展和农民收入的相关数据进行了实证分析,结果表明:生态旅游发展不仅对农民收入增长存在强正相关,也是农民收入持续增加的关键驱动力。应通过建构政府引导、企业经营、农民参与的三方协同机制,进一步发挥生态旅游扶贫的减贫效应,促进农民增收。
