遵循评价体系构建基本原则,从高等教育生态承载力理论内涵出发,构建省域高等教育生态承载力评价体系。评价体系涵盖了生态弹性度、资源与环境承载力、承载压力度3个系统层,并基于改进熵权法对中国省域高等教育生态承载力进行评价及空间格局分析。研究发现:承载压力度、资源与环境承载力对高等教育生态承载力影响作用最大;中国高等教育生态承载力空间格局差异显著,表现为地区间和地区内不均衡发展;地区间和地区内生态弹性度差异最为明显,多数省份存在明显长短板共存现象。据此,提出相关对策建议,为我国高等教育生态系统高质量发展指明路径。 相似文献

人们对资源的忧虑,经历了一个转变过程。由可耗竭资源的有限储量所带来的紧迫感趋淡。由生态承载力的衰减所引发的负面后果日益明显。从二氧化碳排放所引出的气候变化问题,是自然生态系统容纳和消除污染排放物的能力已然不足的一个反映。通过对贯穿上述认识转变过程的经济学研究文献的梳理可知,国外在此方向上的主要分析工具是气候变化综合评估模型。该类模型的优点是把经济系统与自然生态系统集成在一起,使得对碳排放的预测具有微观基础,但也因模型复杂而处理难度较高。它的一个应用是:碳减排力度是应立即强力推进。还是可渐进强化,研究文献中围绕这一问题的争论就是以气候变化综合评估模型为基础而展开的。 相似文献

This article presents two studies that examine whether leader supportive behaviors facilitate knowledge sharing and employee creative problem‐solving capacity, thereby enhancing creative performance. The findings from both studies indicate that leader supportive behaviors are directly and indirectly related, through both internal and external knowledge sharing, to employee creative problem‐solving capacity. In addition, creative problem solving was related to the two dimensions of creative performance—fluency and originality. However, a test of the mediation model indicated that creative problem solving only mediated the relationship between internal knowledge sharing creative performance and originality. These findings highlight the complex process by which leaders facilitate both internal and external knowledge sharing and employee creative problem‐solving capacity, thereby improving employee creative performance. 相似文献

Today's startups are a major source of innovation, as they employ emerging technologies to invent products and reinvent business models. Corporations that embrace an open innovation strategy increasingly look to startups as a source of external innovation. Corporate accelerators offer a potent approach to nurturing innovations from entrepreneurial ventures. However, the vast differences between corporations and startups make collaboration a challenge. Corporate accelerators need to be designed effectively to add value for startups and create innovation benefits for the company. Based on information obtained during interviews with managers and participants of corporate accelerators (n=40), managers receive a framework and strategies for designing corporate accelerators. To leverage startups’ innovation and to make corporate accelerators an effective part of a firm's overall innovation strategy, managers need to systematically and thoughtfully consider the design dimensions of proposition, process, people, and place. 相似文献

针对突发事件下的应急物资调运问题,考虑了多个地区同时受灾以及多个出救点需要对其进行救灾并且各出救点的运力有限的情况,以最小化总的车辆运输费用,最大化救灾效率、各受灾点的救灾满意度,以及各受灾点得到救助的公平性为目标,建立了该问题的多目标混合整数非线性规划模型,并提出了一个基于两层架构协调的迭代式遗传算法进行求解。基于仿真数据的实验结果证明了所提出的模型和算法的有效性。 相似文献

State capacity has become one of the most discussed concepts in development economics and political economy. In this survey we argue that the study of economic history provides vital insights into the process through which modern states have acquired ‘state capacity’. By evaluating the process of state building across a range of different countries in Europe and Asia, we are able to ‘decompress’ the relationship between state capacity and economic growth. Our analysis emphasizes the variegated nature of the state building process. We focus on recent research that helps to elucidate the mechanisms that relate state capacity to economic growth. 相似文献

传统经济学低估了环境作为生产要素的基础性和重要性,主张把环境容量作为一种基本生产要素,并在此基础上论述了环境容量生产要素市场的宏观调控功能,分析了这种调控机制的政策目标、政策手段和政策运转模式。环境容量生产要素宏观经济调控政策可以作为一种常态政策,同财政、货币等宏观政策共同作用于社会,谋求经济的良性可持续发展。 相似文献

While climate change will expose regions to similar impacts, the extent of those impacts and effective response at the local level will be determined not only by the location's sensitivity and vulnerability but also by local groups and individuals’ capacity, including their institutional links, social networks and motivation to action. In parallel, scientific information and research plays a critical role in informing climate change adaptation by providing both an improved understanding of the actual climate risks and response alternatives.The paper focuses on two local-scale intervention research projects undertaken in urbanised coastal areas in Brazil and in Australia concentrated on improving the dialogue between ‘those who make science’ and ‘those who use science to make decisions’ in order to make climate science more useful, and creating purposeful collective action, respectively. A conceptual model is devised to investigate how intervention research could aid adaptive capacity by generating new knowledge and facilitating change towards climate change adaptation at the local level. Drawing on the findings, a framework is proposed to advance the role of intervention research in policy development for enhancing adaptive capacity. 相似文献
