绿色增长下的导向性技术创新选择研究

针对如何正确引导 GHG 排放的气候反馈经济损失下导向性技术创新，以实现长期的绿色增长这一问题，基于 DICE 模型，重构导向性技术创新不同的动力要素及其与气候变化之间的内生关系，建立了可体现绿色增长“均衡性”、“包容性”和“可持续性”的非线性最优控制模型。数值仿真结果显示: 气候反馈经济损失不容小觑; 偏于生产的绿色技术创新导向下社会生产力强劲但存在气候环境恶化风险，偏于减排的绿色技术创新导向下气候反馈经济损失小但存在增长动力匮乏风险，二者虽均可实现长期的绿色增长，但中性的绿色技术创新导向会更稳妥; 偏于生产的绿色技术创新导向下人均消费变化率在短期内会显著提升。     

教育时空拓展:教师专业成长的机遇与挑战

随着人类文明的进步、社会的发展以及信息技术的普及，教育时间和空间得到迅速拓展。教育时空拓展正如一把双刃剑，给教育活动的实施带来机遇的同时也带来了挑战。教师作为教育活动的主要组织者和实施者，在享受机遇的同时也要迎接教育时空拓展所带来的挑战。通过分析教育时空拓展的内涵与表征，发现教师专业成长正处在社会化、终身化与数字化的发展大潮中，因此教师要充分利用好教育时空拓展带来的机遇，同时慎重应对由此面临的挑战，不断提高应变能力，以促进教师专业成长和教育事业的发展。     

Another economy: towards a cultural dialectics between energy and society

The looming oil crisis, pollution, and climate change have pushed governments, corporations, and individuals to think of new policies, new objects/products and new manners to market them – usually under the label of “green economy” (or the shifting towards a sustainable economy).

The changes that are on the way as a result of the envisaged “green revolution” need a broad vision that couples the economy of energetic techniques with the related socio-cultural economy that is induced by, and at the same time reciprocally influences, the mere technical transformations.

Based on previous analysis of theories of socio-technological change and putting at its center the concept of subjectivation in social sciences, this article proposes a theoretical understanding of cultural shifts and their relationship with changes in the practices of production, transfer and use of energy.

First part presents a schema of subjectivation in triangulation, that links the biological level with the material culture and with the representational realm of normativities in our society. It will be developed through the example of electric vehicle as metaphor of the energetic transition. Through this understanding, second part deals with the modeling of the three items as a processual energetic system by using the concepts of surplus and expenditure. Within this frame, we show how disruptions in one of the poles of this model influences the others and bring about changes in the entire Anthropo-Social level. Third part proposes possible types of emerging subjectivities and advances the idea of extending the realm of consciousness to the energetic transfers and their potentiality.     

Service diversification and growth of professional service firms

This study investigates the impact of service diversification on the rate and mode of firm growth in professional service firms (PSFs). Drawing on the extant PSF literature, we identify differing views regarding the growth impact of service diversification. Specifically, some scholars suggest that the external client benefits associated with service diversification should allow PSFs to expand revenues at a rapid pace and pursue less merger and acquisition activity, whereas others imply that increased diversification can cause internal challenges with respect to learning costs, coordination and innovation that can limit the rate of revenue growth and encourage more mergers and acquisitions. We test these competing views using longitudinal data on 137 accounting firms and cross-sectional data on 125 law firms and find that service diversification is negatively associated with the rate of firm revenue growth and positively associated with the use of mergers and acquisitions.     

科技金融结合试点政策对地区经济增长影响研究——基于科技创新与产业结构合理化的视角

科技金融是"第一生产力"与"第一助推力"的有机结合,承担着带动地区经济高质量发展的重要使命.基于当前我国科技金融结合不断推进的背景,文章以2007—2016年我国共285个地级市的面板数据为例,运用双重差分法(DID)对科技部、中国人民银行等五部门推行的科技金融结合试点政策对试点地区经济增长的带动效应及机制进行检验.结果表明:第一,科技金融结合试点政策能够有效带动试点地区经济增长,这一结论具有稳健性;第二,科技金融结合试点政策对试点地区经济增长的带动作用存在显著的地域性差异,东部最强、中部次之、西部最弱;第三,进一步的机制检验表明科技金融结合试点政策能够通过提升地区科技创新水平和推动产业结构合理化的双重路径带动地区经济增长.为了进一步推动科技与金融相结合,提升地区经济发展水平,各地政府应高度重视科技金融结合试点政策对地区经济发展的正外部性,积极申报试点城市建设.同时,应结合各地市情社情制定差异化试点政策,大力提升科技创新与产业结构合理化水平,充分发挥其对地区经济增长的中介作用.     

乡村振兴：城镇化、制度质量与区域经济增长

在脱贫攻坚、全面建成小康社会的重要阶段，城乡之间发展不平衡和农村发展不充分成为我国社会发展的主要问题。制度质量在城镇化发展与区域经济增长之间的积极效用，为推进区域经济增长、城镇化发展至关重要。文章基于我国30个省(市、区)2010—2015年省级面板数据，实证探究城镇化发展、制度质量与经济增长的内在互动机理。研究发现，制度质量、城镇化发展都会对经济增长产生积极正向的影响，在城镇化发展程度较好、制度质量较高的地区，区域经济增长相对较快。研究结论可为政府缩小城乡差距、推进城镇化发展提供理论依据，为制定经济政策、营造良好制度环境、招商引资提供支持，为地区经济增长产生良好的互动效应。     

高质量发展背景下现代服务业经济增收效应研究——基于重庆市的实证分析

现代服务业的高质量发展在一定程度上决定着当前阶段我国社会主义现代化水平，这是未来一定时期内实现经济发展和产业转型升级的关键引擎。通过择取1996—2017年全国层面的平衡面板数据，基于双重差分法和合成控制法对现代服务业综合政策在重庆市产生的经济增长效应做出合理化评价。实证结果表明：整体而言，现代服务业综合政策对重庆市产生明显经济增收效应。随着时间的推移，这种增收效应具有显著促进作用，但其通过政策红利动力驱动而产生的边际效应却趋于弱化。为解决内生性问题，通过进行一系列安慰剂检验，确保结论的稳健可靠。     

A Qualitative Case Study on Recovery and Personal Growth in Korean Drug Addicts

ABSTRACT

In recent years, crimes related to drug smuggling and production have gradually increased in Korea. This qualitative case study explores the experiences of Koreans recovering from drug addiction and identifies specific details and mechanisms of recovery. For this purpose, participants were selected based on criteria such as engaging in social activities after recovery from addiction for 3 years or more. Next, one-on-one in-depth interviews were conducted with five voluntarily consenting participants. Data were analyzed using the within-/cross-case analysis suggested by Creswell. Substantial personal growth took place in the recovery process for drug addicts. Nineteen themes were identified as manifestations of personal growth through within-case analysis. Four common themes were then derived through cross-case analysis. These four common themes were “reconnection with reality,” “embracing the essence of one's own existence,” “reconstructing oneself in social relations,” and “self-love.” The study's results suggest that a recovery program needs to be developed wherein the program not only enables drug addicts to reflect on their current existence but also allows them to develop their specific coping skills. Future research should be broadened to consider the social support mechanism and viewpoints of people including family and local community members in close contact with drug addicts.
