Research summary : This study suggests that strategy and organizational scholars seeking to analyze the impact of exploitation on exploration would benefit by moving away from the generally assumed unitary perspective on exploitation. Specifically, we propose a multifaceted perspective on exploitation by theoretically and empirically distinguishing between repetitive exploitation versus incremental exploitation. We argue that repetitive exploitation can impede exploration and delay firms' responses to environmental changes, while incremental exploitation can impel exploration and accelerate firms' responses to environmental changes. We test our arguments using extensive longitudinal data from the hard disk drive (HDD) industry, and our supportive empirical findings highlight the relevance of our distinction between the two types of exploitation and their very different effects on exploration. Managerial summary : This study offers a solution to the puzzle of why many believe firms cannot excel at advancing existing practices and developing new initiatives, typically described as the trade‐off between exploitation and exploration. We introduce the distinction between repetitive and incremental exploitation and show that only the former type of innovation generates rigidity toward exploration, whereas the latter actually promotes exploration. More specifically, our evidence from the hard disk drive industry shows that those firms emphasizing incremental innovation (as opposed to repetition of their existing practices) were most likely to remain explorative over time, whereas firms emphasizing more repetitive innovation proved less open to changes. We discuss the implications of our findings as suggesting that firms seeking to optimize their innovativeness over the long term should strive to remain active in incrementally innovating their existing practices.

A企业应收账款内部控制面临的问题及对策 总被引:2,自引:0,他引:2
随着信用社会的到来,我国绝大多数竞争性行业的企业都面临"销售难、收款更难"的双重困境.适度的应收账款,是企业适应市场竞争、扩大销售、节约存货资金占用和降低存货成本的需要.但过高比例的应收账款,导致销售收入的增长只能给企业带来账面利润,不能带来维持经营、扩大生产规模所必需的现金流入,使企业的营运能力和偿债能力下降.建立系统、有效的应收账款内部控制制度是企业加强资金周转,提高资金使用效益,保护财产的安全完整的重要手段.本文根据内部控制理论和应收账款内部控制的目标分析了应收账款内部控制的具体方法,目的是发现应收账款控制的薄弱环节进而加强企业应收账款的内部控制. 相似文献

中国石化原油管道运营发展战略探讨 总被引:3,自引:0,他引:3
原油管道运输与铁路、公路、航空、水运等其他原油运输方式相比,具有投资省、成本低、输量大、能耗少、损耗低、污染小、连续、稳定、安全等优势。目前我国原油产地与加工地布局不太合理,特别是中国石化所辖的华北、华东、中南地区,原油加工能力远远超过原油的生产能力。中国石化要用好国内外两种资源、提高整体竞争能力,有必要从战略高度审视管道运营的发展问题。中国石化原油管道发展的战略目标是:根据国内外两种原油资源的供求状况,持续优化调整现有原油管道运营结构,使原油流向更科学、合理、经济;以国内现有的华东、东北地区原油长输管网为基础,与中国石化现有原油管道相结合,建设新的原油长输干线与其联成一体,共同构建一个有机的、能充分接纳国内外两种原油资源的,以及连通华北、华东、中南和东北地区的环形原油管道运营网络系统。为实现上述目标,应持续优化调整原油管道运营结构,扩大原油管道运营市场。 相似文献
