海洋经济信息资源是海洋资源规划、管理、保护和合理利用的基础信息,是国家重要的基础性、战略性信息资源之一。然而,"共享"与"保护"之间的矛盾性造成了我国海洋经济信息资源管理缺乏协调性、统一性,因此需要开展海洋经济信息资源统一化、标准化管理,加快实施海洋经济信息资源的共享关键技术,建立海洋信息共享机制,建立海洋经济信息资源的安全管理体系,积极参与海洋经济信息资源共享的国际合作。  相似文献

The objective of this research is to examine the role of sector-specific information technology (IT) developments and their significance in terms of the revenue and earnings before tax of Logistics Service Providers (LSPs), as well as the impact of these developments on the flexibility and integration of LSPs. A survey questionnaire was conducted with 284 LSPs participants. The data provided by the 51 responding enterprises provided a representative sample for the analysis of the sample population and the drawing of general and relevant conclusions related to basic population. It can be concluded that their revenue, earnings before tax and degree of integration into the supply chain depend on the sector-specific IT developments carried out by the given enterprise. IT investments will remain important in the future and the introduction and leveraging the best technologies may yield competitive advantages and higher financial rewards for LSPs.  相似文献

在就跨境电商对华商网络贸易所具有的替代效应与互补效应进行理论分析的基础上,利用古诺模型分析市场均衡的结果及贸易效应,采用面板数据实证检验跨境电商对华商网络贸易的影响,结果表明跨境电商对华商网络贸易的互补效应大于替代效应:一方面,由于华商网络对出口贸易的影响尤为显著,而跨境电商平台又以出口贸易为主,从而跨境电商对华商网络出口贸易的影响较大;另一方面,跨境电商平台偏向于差异化产品贸易,因而跨境电商对差异化产品的华商网络贸易有着较大影响。也就是说,跨境电商对华商网络贸易的互补效应在出口贸易与差异化产品贸易上表现得尤为显著。  相似文献

采用2005—2014年我国上市公司独立董事对议案事项意见的独特数据,从明确监管议案事项、非明确监管事项和股权分置改革等三方面深入考察其对独立董事出具否定意见的影响。研究发现,在我国上市公司中,对明确监管议案事项出具否定意见概率低,说明“逆淘汰”机制和“任人唯亲”董事会文化的存在使得监督效果大打折扣。同时发现,在股权分置改革后,独立董事对议案事项出具否定意见概率更低;出于规避法律风险的考虑,独立董事对明确监管事项出具否定意见的概率相对较高。因此,监管层应加强对各类议案事项检查力度而非仅仅明确监管事项;科学厘清独立董事在董事会决策中的责任边界,明确独立董事承担的法律风险。  相似文献

Research Summary: We study the use of corporate philanthropy as a form of reputation insurance, developing a formal model of such insurance to examine how the terms of insurance in equilibrium change under different assumptions about the firm and its stakeholders. We then test the predictions from this model in the U.S. petroleum industry and find that philanthropic donations offer insurance‐like benefits, but are also positively associated with subsequent oil spills—firms that give more, spill more—with this association being stronger for spills that are under firms’ control and in states with low civic capacity. These results are consistent with an adverse selection/moral hazard equilibrium and suggest that the use of philanthropy as reputation insurance may benefit firms at the cost of society. Managerial Summary: Firms that donate to social causes develop a reputation for being socially responsible, and are often given the benefit of doubt when negative information about them comes to light. But are philanthropic firms truly more responsible? We argue that firms that donate more may be more likely to do harm—those that expect to do harm later are likely to give more now, and those that know their reputation protects them may become less careful. Evidence from the U.S. petroleum industry is consistent with this argument, with firms that give more having more subsequent oil spills, but only the type of spills that are under the firm's control, and only in states where the firm faces weaker scrutiny.  相似文献

This article develops theory about an agency problem affecting the strategic human capital (SHC) of the firm. It proposes three categories of SHC‐related choices managers must make that imply a trade‐off between near‐ and long‐term performance. Dispersed shareholding, firm coverage by securities analysts, and their practice of publishing quarterly earnings forecasts are argued to entail a bias in management incentives, shifting the balance in this trade‐off toward near‐term performance. To restore the balance, securities analysts would need to distinguish transitory from recurring effects of SHC‐related choices in their valuation models (e.g., treating certain labor cost savings during cyclical downturns as transitory). Restoring the balance would also require them to anticipate long‐term effects in their long‐term earnings forecasts (e.g., long‐term positive effects of retaining employees with valuable skills during cyclical downturns). The article discusses specific transitory cost effects and long‐term effects they could potentially take into account. The skills and incentives needed by analysts to account for such effects are argued to vary across firm segments.  相似文献

基于2003—2016年我国A股上市公司的经验数据,以企业表内列报的预计负债金额与表外附注中披露的或有事项频数为考察对象,实证检验了管理层权力对或有事项信息披露的影响。研究发现,管理层权力与表内列报的或有事项信息显著负相关,而与表外披露的或有事项信息显著正相关;进一步发现,随着环境不确定性的增加,管理层权力对企业表内预计负债列报的负向影响显著增强,而对表外或有事项披露的正向影响明显减弱。在当前外部环境瞬息万变、内部治理机制弱化的背景下,管理层可能会利用其控制权操控或有事项信息的披露方式,自我服务偏好明显。  相似文献

Learning is often a central element of tourism. Tourists can learn actively, i.e. with a specific purpose, as well as passively through the comparison of values, norms and customs. It has been argued that travel supports active learning that has positive outcomes for sustainability, for instance, in the context of conservation. Yet, the complexity of active and passive learning processes and their outcomes for environmental sustainability and sustainable lifestyles remain insufficiently understood. Against this background, the paper discusses selected learning outcomes for transportation (air travel), accommodation (hotels) and activities (theme park visits). Findings suggest that “desirable” learning (defined as pro-sustainable development learning) in tourism may be very limited, while in particular, passive learning processes which redefine social norms frequently have outcomes that are largely detrimental to sustainable lifestyles. They include forms of moral licensing, the diffusion of responsibilities as well as the attenuation of the negative consequences of travel. Given the economic, social and cultural importance of tourism vís-a-vís its global implications for environmental sustainability, learning outcomes in tourism deserve to be studied in greater detail, while strategies need to be devised to enhance sustainable learning effects.  相似文献
