促进有色金属产业集聚是提升贵州省有色金属产业竞争力的主要途径之一,因而准确测度和把握有色金属产业集聚与贵州有色金属产业竞争力的关系是非常必要的。文章把贵州省放在西部九省中进行对比分析,选取区位熵反映有色金属产业集聚度,选择企业数量区位熵反映矿产资源产业区域集聚度,选取产业产值区位熵反映有色金属产业经济集聚度,而有色金属产业竞争力则选取产值利润率借以反映。具体实证数据均来源于西部9个省份的2013统计年鉴与2013年的中国有色金属工业年鉴。通过实证研究认为贵州省有色金属产业存在诸如区域集聚、经济集聚不足,产值利润率低下,产业集聚效应难以充分发挥等问题。最后提出提升贵州省有色金属产业竞争力的相关政策建议。 相似文献

This paper considers the extent to which South African households have deleveraged, since the global financial crisis of 2007/2008. We extend the official South African Reserve Bank business cycle methodology to date financial cycles, from which we identify the peaks and troughs of the South African financial cycle going back to 1966. Our composite financial cycle index peaks in April 1974, January 1984 and May 2007; it has bottomed out in July 1979 and February 1999. Thus, we still await the trough. We further compare and contrast the deleveraging process in the current downward phase to the experiences from previous financial cycles. We find that the average period of the financial cycle in South Africa is much longer (approximately 17.3 years) than that of the business cycle (approximately 5.8 years), and that deleveraging has not yet matched the degree of deleveraging seen in previous downward phases. Our results suggest that further deleveraging is necessary, before we can expect to turn the financial corner. 相似文献

The circular economy emerged as an alternative model to the linear system, which now appears to be reaching its physical limitations. To transition to a circular economy, companies must not only be aware of but also engage in more sustainable practices. For such a transition, companies must rethink and innovate their business models and the ways they propose value to their clients while simultaneously considering environmental and social facets. This systematic literature review sought to map out from the company perspective the key topics interrelated with innovation and the circular economy, describing the internal and external factors to consider in such transition processes. Key lines of research were identified, and suggestions for future research and for facilitating movement toward a circular economy are provided. This work contributes to deepening the literature by identifying the priority areas concerning the circular economy and encouraging future research that meets international standards of excellence. 相似文献

基于2007-2018年中国A股上市公司数据,本文考察了机构交叉持股对企业价值的影响及其作用机制。研究发现,机构交叉持股显著提高了企业价值,在考虑内生性问题和替换主要变量后结论依然较为稳健。交叉持股机构投资者能够成为更加积极的监督者,主动参与公司治理,缓解代理问题,同时促进同行业企业间产品市场协作,改善企业的产品市场表现,进而提升企业价值。此外,相比其他类型的投资者,长期、独立以及稳定型的交叉持股机构投资者对企业价值的促进作用更显著,进一步印证了监督治理渠道的作用。机构交叉持股推动产品市场协作,主要是通过提高企业创新能力和营业利润率。本文结论证实了机构交叉持股的正向协同效应,对完善中国资本市场制度体系和促进企业可持续发展具有重要意义。 相似文献

应用双指耦合结构和枝节加载谐振器(Stub-loaded Resonator,SLR)实现了一款基于阶梯阻抗谐振器(Stepped Impedance Resonator,SIR)的滤波器。该滤波器具有3个通带,带外抑制较好,工作频段提高。通过调整阻抗比可调节第二、三通带的谐振频率;SLR结构能够增加通带数量;SLR结构和双指耦合结构均能改善滤波器的S参数。HFSS软件仿真表明,3个通带的中心频率分别为3.5 GHz、6.6 GHz、9.2 GHz,对应的分数带宽分别为5.7%、3%、2%,S11分别为-18 dB、-22 dB、-24 dB,通带内的S21分别为-1.8 dB、-1 dB、-1 dB。电路的测量结果与仿真结果较为吻合。该滤波器在5G通信的低频段具有应用前景。 相似文献

Using university administrative and survey data drawn from the AlmaLaurea Consortium, we analyze the effect of time to degree on the early labor market performance of Italian graduates. The empirical strategy allows identifying separately the impact of elapsed time to degree on the transition from university to work and on earnings from other determinants specific to the academic path completed. Findings suggest that delayed graduation reduces the employment probability (0.8% points for each year of delay), and this effect is still persistent five years after graduation. Once employed, graduates not completing their degree within the minimum period are also penalized in their net monthly earnings, even five years after graduation. The most penalized groups are women and graduates in non-scientific fields. 相似文献

Workforce composition in organizations has become increasingly diverse. As an important step in determining how workforce diversity leads to firm performance, we proposed relational coordination as a mediator through which diversity in age and education indirectly affects firm performance. We also highlighted two human resource management practices (structural empowerment and multisource feedback) as critical contingencies that moderate the effects of workforce diversity on relational coordination and firm performance. We conducted hierarchical multiple regression on multisource data (including responses from senior directors, department directors, managers, and employees, as well as financial performance) from 189 Korean firms in the manufacturing sector, which yielded support for our hypotheses. These findings offer novel theoretical and practical insights into the effective management of workforce diversity. 相似文献

Banking integration is widely considered as the last stepping stone of economic integration, especially at the regional level. This paper aims to introduce extended measures of banking openness and the overall balanced degree of integration through capital flows. Using the quarterly data from the ASEAN-6 economies (Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam) from 1996Q4 to 2016Q4, the obtained empirical results reveal that: (i) the degree of banking openness, which measures the total inflows and outflows divided by the total banking assets of the given country, remains low and even slightly decreases, despite the increasing cross-border banking and greater economic links among ASEAN-6; (ii) the overall degree of balance, which calculates the balance and the diversification of outward and inward integration, fluctuates over time but reaches the well-balanced level. Furthermore, the research highlights main drivers of the banking integration in this region, such as regulatory quality, bank size and the global credit risk. These findings have important policy implications for banking stability and integration in ASEAN-6. 相似文献
