The Jatropha biofuels sector in Tanzania 2005-2009: Evolution towards sustainability?

Biofuel production has recently attracted much attention. Some anticipate substantial social and environmental benefits, while at the same time expecting sound profitability for investors. Others are doubtful, envisaging large trade-offs between the pursuit of social, environmental and economic objectives, particularly in poor countries in the tropics. The paper explores these issues in Tanzania, which has been an African forerunner in the cultivation of a bio-oil shrub called Jatropha curcas L. We trace how isolated Jatropha biofuel experiments developed since early 2005 towards a sectoral production and innovation system, and we investigate to what extent that system has been capable of developing and maintaining sustainable practices and producing sustainable outcomes. The application of evolutionary innovation theory allows us to view the developments in the sector as a result of evolutionary variation and selection on the one hand, and revolutionary contestation between different coalitions of stakeholders on the other. Both these processes constitute significant engines of change. While variation and selection are driven predominantly by localised technical and agronomic learning, the conflict-driven dynamics are highly globalised and occur primarily as a result of reflexive learning about problematic sustainability impacts. The sector is found to have moved some way towards a full sectoral innovation and production system, but it is impossible to predict whether a viable sector with a strong “triple bottom line” orientation will ultimate emerge, since many issues surrounding the social, environmental and financial sustainability still remain unresolved, especially relating to local and global governance.

我国文化产业投融资问题及策略研究

文化产业资本运营对于促进文化产业快速健康发展具有重要意义。而当前我国文化产业投融资发展尚不完善。为此,从宏观投资支持的层面看,应营造良好投资环境,理清投资范围,优化投资结构,确立投资重点,塑造市场化投资主体,积极培育新的投资形式;从微观融资支持的角度看,应加强内部融资,扩展信贷融资,发挥资本市场直接融资功能,吸引社会资本,建立文化产权交易平台,培育文化产业保险市场,组建相关产业投资基金。

The influence of informal social media practices on knowledge sharing and work processes within organizations

Contemporary information technologies such as social media have invigorated the way knowledge is shared within organizations to the extent that we have to rethink and reassess our understanding of the role and influence of technology in organizational processes and knowledge sharing. This paper uses the strategy as practice lens guided by the interpretivist philosophy to understand the influence of informal social media practices on knowledge sharing and work processes within an organization. The paper uses empirical evidence from the case study of a telecom organization in Tanzania to gain theoretical insight into informal social media practices and knowledge sharing. This research contributes to the Information Systems (IS) literature by asserting that organizational processes are achieved by mundane knowledge sharing mediated by informal social media use within the organization. Also, the study contributes to IS literature by highlighting how emerging informal practices are essential to daily processes within organizations.

资产专用性对企业技术创新的影响：竞争战略的中介作用

基于交易成本理论、技术创新理论与战略管理理论,引入企业竞争战略作为中介变量构建资产专用性、竞争战略与企业技术创新之间作用关系的理论模型,并利用我国在中小企业板上市的243家工业品制造业企业2010-2018年的平衡面板数据对模型进行实证检验.结果表明:企业的资产专用性对技术创新具有显著的负向影响,对成本领先战略具有显著的正向影响,对差异化战略具有显著的负向影响;成本领先战略对技术创新有负向作用但不显著,在资产专用性与技术创新之间起部分中介作用;差异化战略对技术创新具有显著的正向影响,在资产专用性与技术创新之间发挥了完全中介作用.研究结论对企业与政府的管理启示为:企业要设法降低资产专用性对技术创新的阻力,政府的技术创新政策制定应对资产专用性高的企业给予倾斜性的扶持,以促进企业发挥开展技术创新的积极性.
