Abstract :
This study aims to investigate the impact of ICT capital services on economic growth and energy efficiency in China at both national and industrial levels during the period 2000-2020. To achieve this aim, this study introduces a measurement method for capital services, explores ICT's contributions to economic growth, and analyzes the impact of ICT on energy efficiency. The empirical results of this study indicate that although the ICT capital services scale is relatively small, accounting for only 8.87% of the total in 2020, its growth rate is faster than that of non-ICT capital services, and the distribution of ICT capital services varies widely among different industries. Additionally, based on the economic growth decomposition framework, this study finds that the contribution of ICT capital services to economic growth is 6.95% on average. It is significantly higher in certain industries, such as Financial industry; Information transmission, software and information technology services; Construction; and Manufacturing compared to others. The total factor energy efficiency (TFEE) reveals that industries with higher energy consumption have lower energy efficiency, while the panel regression model illustrates that the development of ICT has a positive impact on improving energy efficiency, with variability across industries. Overall, the findings of this study provide crucial scientific evidence and policy implications for promoting the development of ICT and integrating it with various industries, which can significantly contribute to boosting economic growth and energy efficiency.

Abstract :
The importance and urgency of improving energy and carbon emissions efficiency in mitigating climate change and achieving carbon neutrality have become an increasingly relentless focus in recent years. Assessing the performance of energy saving and carbon emissions reduction is a significant necessity to achieve sustainable economic development. Therefore, from the perspective of production economics, this paper presents a review of the definition, models, and input-output variables for measuring total-factor energy efficiency and total-factor carbon emissions efficiency. Relevant literature in this field, published between 2006 and 2021, has been systematically analyzed using CiteSpace software, which includes a quantitative and visual review of a large body of published literature. This review found that the current definitions of total-factor energy efficiency and total-factor carbon emissions efficiency are confusing and misleading. Furthermore, future research on energy saving and carbon emissions reduction should incorporate subject areas such as economics, energy, and ecology.

Abstract :
This research examines the influence of intellectual capital on financial and environmental performance with a mediating role of green supply chain management and a moderating role of financial resources. Structural model estimation was conducted on the data set of 324 Pakistani manufacturing SMEs and showed that intellectual capital significantly encourages green supply chain management as well as significantly contributes to financial and environmental performance. Green supply chain management partially mediates the relationship between intellectual capital and performance both the financial and environmental. Financial resources significantly strengthen the relationship between intellectual capital and green supply chain management. In light of the results, we suggest that firms should encourage intellectuality among their managers and employees to adopt green practices that can improve their financial and environmental performance. In addition, it is also suggested for managers and CEOs to effectively manage financial resources that are necessary for green practices.

Abstract :
Energy efficiency is crucial to the 2030 UN Sustainable Development Goals (SDGs), but its widely measured indicator, energy intensity, is still insufficient. For this reason, in 2006, total factor energy efficiency (TFEE) was proposed with capital, labor, and energy as inputs and GDP as the desirable output. The later TFEE approach further incorporated pollution as the undesirable output. However, it is problematic to regard GDP (the total value of final products) as the desirable output, because GDP does not include the intermediate consumption, which accounts for a large part of the production activities and may even be larger than the value of GDP. GDP is more suitable for measuring distribution, while VO (value of output) is more appropriate for sustainable production analysis. Therefore, we propose a VO TFEE approach that takes VO as the desirable output instead and correspondingly incorporates the other intermediate materials and services except energy into inputs. Finally, the empirical analysis of the textile industry of EU member states during 2011-2017 indicates that the VO TFEE approach is more stable and convergent in measuring energy efficiency, and is more suitable for helping policymakers achieve the SDGs of energy saving, emissions reduction, and sustainable economic development.

Abstract :
Improving energy efficiency is an effective way to address the issues of economic development, energy saving and emissions reduction. For any important industries it is therefore necessary to measure energy efficiency and set a practical target for it. In this paper, we use CCR, SBM and energy intensity to measure the energy efficiency of the paper industries of 22 EU countries. Results indicate that the SBM and CCR efficiency value is more meaningful for policy makers than that of energy intensity, as measurement results of energy intensity deviate from reality and economic efficiency. The CCR and SBM have roughly the same fluctuation trends and the average SBM energy efficiency value is 0.71, always 10 percent lower than CCR model, as it takes simultaneous account of both the optimal input-output and has more discriminatory power in efficiency measurement. Furthermore, EU policy makers could improve energy efficiency by raising energy prices. As for the 2030 EU target of energy saving and emission reduction, the EU should pay more attention to five major paper producers: Finland, Sweden, Germany, the United Kingdom and Italy.

Abstract :
This research evaluates the importance of government support in the financial and environmental performance of SMEs with the mediating role of differentiation and cost leadership strategy. For testing the model, data were collected from 315 owners/managers of Pakistani SMEs through a survey. The results of the structural equation modeling spectacle that both financial and non-financial incentives of government have a significant positive influence on financial performance, environmental performance, differentiation and cost leadership strategy. Differentiation strategy partially mediates the paths between government incentives (financial and non-financial) and firms' performance (financial and environmental). However, cost leadership strategy fully mediates the relationship between government financial incentives and environmental performance, while it partially mediates the connection between government non-financial support and environmental performance. In addition, the cost leadership strategy partially mediates the path between government incentives (financial and non-financial) and financial performance. This research recommends the government and policymakers to provide financial and non-financial incentives to the industrial sector that can configure their competitive advantage and performance. In turn, these firms will able to contribute to environmental and economic growth. Additionally, firms need to build ties with the government to get valuable resources that are beneficial for competitiveness as well as environment and financial performance.

Abstract :
以2009年中关“轮胎特保”案作为外部冲击构建“准自然实验”,考察贸易摩擦对中国上市公司股价波动的影响.结果 表明:贸易摩擦对中国相关上市公司的股价存在着显著的负向影响;短期内贸易摩擦对股价的影响渠道主要是投资者对企业的投资信心,与企业的经营绩效无显著相关;从“时间效应”和“阶段效应”的探讨看,贸易摩擦对股价的影响仅存在“短期效应”,在开始和正式裁定两个阶段对企业股价产生了负面影响;贸易摩擦对前向关联产业的股价具有显著的负向影响,而对后向关联产业的股价影响则不显著.

Abstract :
Multiple tangible and intangible determinants affect the survival and success of a small and medium enterprise (SME). In turbulent markets, however, compared to exogenous effects, a firm's internal capabilities are seen as major sources of economic value creation and sustainable competitive advantage. This study empirically examines the effects of pivotal internal capabilities, namely entrepreneurial orientation, information technology (IT) capability, and intellectual capital (IC), on the financial and non-financial performance of SMEs that operate in the emerging market of Pakistan. Data were collected through self-reported questionnaires, from a sample size of 307 SMEs. The study hypotheses were tested through the structural equation modelling (SEM) technique of AMOS 21. The statistical results show entrepreneurial orientation, IT capability and intellectual capital as significant contributors to both financial and non-financial performance. Despite its limitations, the study offers both future-research directions and policymaking recommendations for practice. Namely each SME ought to focus on self-developing those internal capabilities that render sustainable its competitive posture. © 2019 - IOS Press and the authors. All rights reserved.

Abstract :
文章以2014—2016年发布的《全球创新指数》创新得分排名均位于前50的国家为研究对象,以创新带来的最终市场价值来衡量创新产出,引入非链式两阶段DEA测算国家创新效率与创新中间产出的最优配置情况。结果表明:大部分国家创新效率总体水平偏低,主要原因在于创新的市场化效率落后,创新市场化效率随人均GDP增加呈"U"型趋势;创新中间产出对国家经济发展的支撑程度普遍偏低,创新的高市场化效率并不代表创新中间产出的高利用率,各国均存在不同程度的创新中间产出优化配置低效的问题。不同类型国家应根据自身的创新绩效水平制定相应的改进策略,并根据各国创新中间产出实际情况进行相应调整。
