当前融媒体的发展已成为一股不可逆转的潮流。传统媒体的转型需要媒体行业整合自身优势,从资源、内容、宣传、价值等方面入手,对生产运营进行改革,重建媒体与用户之间、新媒体与传统媒体之间的“链条”。论文以杭州二更网络科技有限公司为例,具体阐述了“二更”的传统媒体转型,将新媒体融入“二更”文化,打造属于“二更”的融媒体生态圈。 相似文献

以制造业上市公司为样本,探讨社会资本能否抑制僵尸企业对健康企业创新的挤出效应。结果显示:僵尸企业每增加1%,健康企业的发明专利数降低0.41%。僵尸企业的创新挤出效应大部分由非国有企业承担,国有企业的创新并未受到影响。健康企业通过积累不同类型的社会资本来抑制僵尸企业对其创新造成的挤出效应。非国有健康企业的连结型社会资本对创新挤出效应的抑制作用最强,结合型社会资本的作用次之,桥接型社会资本的作用最小。 相似文献

This paper examines how firm characteristics and local anti‐corruption effort moderate the influence of political connections on enterprises’ private R&D investment using data from 2,587 Chinese A‐share listed enterprises. Our results show that the local anti‐corruption institutional environment significantly moderates the strong relationship between political connections and enterprises’ private R&D investment. Firm characteristics (i.e., firm size and firm age) also show a moderating effect on the relationship between political connection and enterprises’ private R&D investment; larger and older enterprises are more likely to have innovative resources and business cooperation partners, and thus are able to reduce their degree of reliance on political connections and government funding. The results of our study suggest the importance of having a transparent and fair institutional environment for enterprise innovation activities. 相似文献

With rapid increases in global food demand and production, oil palm expansion constitutes a major emerging challenge for forest conservation in Amazonia and other tropical forest regions. This threat is evident in the Peruvian Amazon, where local and national incentives for oil palm cultivation along with growing large-scale investments translate into accelerated oil palm expansion. Environmental sustainability of oil palm cultivation in the Peruvian Amazon is contingent on policy incentives for expansion onto already-cleared lands instead of biodiverse, high carbon primary rainforests. Previous research indicates that while industrial plantations use less land area than local smallholders, companies have a higher tendency to expand into primary rainforests. However, the motivations behind these differing expansion scenarios remain unclear. In this study we combine data from optical and radar satellite sensors with training information, field discussions, and review of public documents to examine the policy incentives and spatial patterns associated with oil palm expansion by smallholders and industries in one of Peru’s most rapidly changing Amazonian landscapes: the Ucayali region of the city of Pucallpa. Based on our satellite-based land cover change analysis, we found that between 2010 and 2016, smallholders utilized 21,070 ha more land area for oil palm than industries but industrial expansion occurred predominantly in old growth forests (70%) in contrast to degraded lands for smallholders (56%). Our analysis of national policies related to oil palm expansion reveal policy loopholes associated with Peru’s “best land use” classification system that allow for standing forests to undergo large-scale agricultural development with little government oversight. We conclude that both sectors will need careful, real-time monitoring and government engagement to reduce old-growth forest loss and develop successful strategies for mitigating future environmental impacts of oil palm expansion. 相似文献

研究目的:基于契约治理和关系治理维度分析农地整治项目治理机制,探究治理机制完善途径。研究方法:理论分析、因子分析、障碍因子诊断。研究结果:(1)农地整治项目契约治理包括控制权配置、风险分担、利益分配和关系协调等机制,关系治理包括信任、承诺、沟通和合作等机制;(2)农户对农地整治项目治理机制的评价(3.50/3.62/3.44)整体处于"一般—比较满意"水平,对政府主导整治项目的评价得分(3.50/3.62)高于非政府主导整治项目得分(3.44);(3)契约治理首位障碍因子为风险分担,关系治理首位障碍因子为沟通;(4)政府主导整治的首位障碍因子为变更通知/技术交底(障碍度5.54%/5.41%),非政府主导整治的首位障碍因子为风险处理程序(障碍度5.42%)。研究结论:合理分担风险、加强信息沟通,是完善农地整治项目治理机制的有效途径;当前农地整治仍应以政府主导为主,非政府主导作为重要的补充形式,还需在实践中继续探索与完善。 相似文献

This paper analyzes the structure of CEO pay in European fixed telecommunication companies, focusing on the impact of state ownership. Results show that, under the (partial or total) control of the state, the level of CEO compensation is lower and pay-performance sensitivity is higher than in privately-controlled firms. This finding suggests the state provides an incentive as well as a monitoring effect. However, when the state holds the majority of the shares, the pay level is significantly affected by the CEO power, suggesting that in these firms, CEOs are more likely to be entrenched with boards and succeed in raising their pay. 相似文献

The forest and landscape restoration (FLR) targets set as part of the Bonn Challenge draw attention to the governance arrangements required to translate national FLR targets into local action. To achieve the targets, actors at multiple levels of the governance scale aim to influence relevant processes on the ecological scale. In this article, we focus on the scale challenges relating to the implementation of Ecuador’s restoration targets, by analysing the implementation of the 2014–2017 National Forest Restoration Plan in the montane Chocó Andino and Bosque Seco landscapes. From 54 semi-structured interviews, a document review, and geographical data analysis, we identified two temporal (i, ii) and three spatial scale challenges (iii, iv, v): i) Political cycles mismatch with FLR timelines; ii) Planning horizons mismatch with FLR timelines; iii) National restoration objectives mismatch with decentralised land use planning realities; iv) The governance level of existing FLR efforts mismatches with the level receiving restoration funds; and v) Tensions exist between the spatial dimensions of biodiversity and water-related restoration efforts. The findings highlight that more attention must be given to scale-sensitive governance to make the process in which national FLR targets are translated into local action more effective. 相似文献

推进建设粤港澳大湾区城市群,尤其应当重视各级政府在该区域治理机制架构中的地位。协调不同法域、不同层级和不同类型地方政府之间的治理权,是推进该城市群协调发展,并率先推进实现新型城镇化转型的基础和保障。就该区域而言,政府治理权的架构可以分为三个层次:根据中央顶层设计的区域布局,推动地方政府转换行使治理权的视阈,合理安排不同地方政府治理权,并建立权力协作机制;由此机制出发,协调区域内各地方的发展方向,深化彼此之间利益共生关系;最后,与利益共享对应,还应当配合财政供给改革,实现区域治理责任的成本共担。 相似文献
