企业创新柔性组态路径研究——一个模糊集定性比较分析

创新柔性对企业在不确定性环境下保持健康稳定发展至关重要,如何提升企业创新柔性受到学界关注。现有文献侧重研究单个因素对创新柔性的净效应,鲜有分析多因素对创新柔性的协同效应。基于组态视角,运用模糊集定性比较分析法(fsQCA),探讨网络能力和知识共创两个层面的5个变量对企业创新柔性的联动效应及其作用路径。结果表明,网络愿景、网络构建、网络管理、联合型知识共创和嵌入型知识共创均不是构成企业高、非高创新柔性的必要条件,且单个前因条件对创新柔性的解释力较弱,说明影响企业创新柔性的因素是多方面的;存在3条提升企业创新柔性的路径,即资源获取型、发展—管理型和单一型;导致企业非高创新柔性的路径有两条,且与高创新柔性路径影响因素存在非对称性关系。研究不仅能丰富创新柔性相关理论,还可为企业提升创新柔性提供思路借鉴。     

一种硬地层高效破岩技术应用分析

沙特阿美ATN区块三开直井段钻遇层段为Jilh、Sudair和Khuff,对应井深在3040-4150m,以白云岩、灰岩及碳酸盐为主,地层坚硬、研磨性强。上部层段页岩不稳定,掉块较严重,造成泥浆比重增大,使得钻进更加困难。使用常规的钻井方法机械钻速低,采用螺杆等井下动力钻具没有效果。现场试验证明,Φ228液动射流冲击器可有效解决硬地层机械钻速慢的难题,针对上述地层岩石抗压强度进行了量化分析,依据液动射流冲击器性能参数与岩石抗钻特性参数关系,结合应用井设计,制定了Φ228液动射流冲击器旋冲钻井提速方案,优选出旋冲钻井参数。在此基础上进一步优化了钻具组合及匹配钻头,并对匹配钻头的抗冲击能力和攻击性进行了分析。在ATN-1123井进行了现场提速应用。应用结果表明,Φ228液动射流冲击器提速效果显著,较邻井平均机械钻速同比提高47%。此次成功应用,为该区块硬地层钻井提速提供了有效技术手段。     

科技型小微企业创新生态系统网络治理研究

建立一个完整、高效的创新生态系统是破解科技型小微企业创新困境、提高创新效率,以及助力新旧动能转换的有效途径。基于生态系统理论和演化动力学模型,构建科技型小微企业创新生态系统网络框架和网络联结模式,利用竞争、互利共生和捕食关系演化模型,分析演化模型的均衡点及其稳定条件。结果发现,创新生态位重叠程度决定了竞争激烈程度,系统演化均衡条件是主体间分工程度高,且嵌入适度。最后,从价值主体和机构主体两个方面〖JP〗提出推进科技型小微企业创新生态系统不断进化的治理策略。     

知识型员工双重社会网络对企业创新绩效作用机制研究

基于企业基础资源观和组织学习理论,从知识型员工个人和组织社会网络两个方面构建知识型员工双重社会网络影响企业创新绩效的理论模型,分析知识共享、组织学习及资源整合在员工双重社会网络对企业创新绩效影响机制中的作用。结果表明：知识型员工双重社会网络对科技型企业创新绩效的作用路径有3条,资源获取与整合、知识共享与学习及员工动态创新能力分别在其中发挥中介作用;在不同类型组织文化环境中,知识型员工双重社会网络对企业创新绩效的作用特征、作用重点以及作用机制存在显著差异,内部整合维度主要通过知识共享和组织学习影响企业创新绩效,外部适应维度主要通过隐性知识传播和资源整合影响企业创新绩效。

Market novelty, competence-seeking and innovation networking

Studies of innovation networking have frequently been concerned with the occurrence of dyadic relationships and with their apparent impact on simple measures of firm-level innovation outputs. This paper takes a more detailed look by analyzing the connection between different types of innovation and forms of networking. Based on the market novelty of innovation outcomes and the extent to which innovation activities require new competences, four types of innovation are identified. It is proposed that these types correlate with various innovation network dimensions, including the volume of networks, the strength and content of ties, and the specificity of ties. Drawing on survey data of 594 innovations realized by Dutch small firms, it is observed that the requirement to access new competences for innovation correlates positively with the number of network partners involved. We also note more subtle connections between types of innovation and networking, including that novel innovation outputs correlate with using network partners as a source of inspiration, whilst new competences associate with networking for knowledge capital. In the latter case, these activities also draw on new and intended ties relatively often, i.e. network partners which are actively sought out for the specific contributions they may make to the innovation process. Finally, innovation which is simultaneously new-to-the market and requires new competences uses strong ties relatively often. Implications for innovation policy and practice are discussed.     

滨里海盆地Adaiski区块盐下成藏主控因素分析

Adaiski区块位于滨里海盆地东南部,构造上属于南恩巴坳陷区。滨里海盆地在早二叠世晚期发育巨厚盐岩,盐岩覆盖之下的的泥盆系-二叠系以碳酸盐岩和碎屑岩沉积为特征。经已钻井证实Adaiski区块盐下油气资源丰富。在对该区块盐下油气基本成藏条件分析的基础上,详细分析了盐下成藏的主控因素,指出盐下成藏的主控因素是碳酸盐岩台地和生物礁的发育和分布,其次孔谷阶盐岩盖层的分布对成藏有重要影响。     

The U.S. tourists’ perceptions of destination China over two transformative periods

This study conducted a textual analysis of The New York Times to examine the U.S. tourists’ perceived image of China as a destination by comparing the two periods of January 1980–May 1989 and January 2005–December 2015. The study found a drastic shift of the U.S. tourists’ affective image of China as a destination from being favorable and positive in the early period to being unfavorable and negative in the recent period. The affective image was characterized by the two domains of Exoticism and Sense of Superiority in the 1980s, as compared to the two domains of Ordinary and Negative National Image in the recent 10 years. Paradoxically, such a sentimental shift on the part of the U.S. tourists occurred while their perception of China’s destination attributes either did not change or grew more positive.
