生物制药产业技术创新能力系统演化的遗传算法模型与仿真研究

基于CAS理论视角,明确生物制药产业技术创新能力的定义,构建生物制药产业技术创新能力系统的概念模型图,找出组成该系统的产业技术创新流程及惯例,并阐述生物制药产业技术创新能力系统的演化机制。与此同时,构建生物制药产业技术创新能力系统演化的遗传算法模型,并通过Matlab软件仿真生物制药产业技术创新能力系统的演化。结果表明,产业技术扩散对生物制药产业技术创新能力强度有显著增强作用,而产业吸收能力作为技术创新惯例则在适应度函数的迭代计算中起到显著约束的作用。     

环境规制与行业异质性对制造业企业技术创新的影响——基于我国沿海与内陆地区的比较

基于行业异质性视角,以2010年—2015年我国省级制造业规模以上企业为样本,将环境规制划分为正式型与非正式型两类,对比分析了沿海与内陆地区环境规制、行业异质性对企业技术创新影响的差异。研究发现：(1)从制造业全行业来看,正式型环境规制对技术创新的影响作用在沿海与内陆地区均显著为正;非正式型环境规制对技术创新的影响作用在沿海地区显著为正,在内陆地区作用不显著;环境规制强度对技术创新的影响作用在沿海地区显著为负,在内陆地区显著为正。(2)环境规制对高污染行业的技术创新作用在沿海地区显著为正,在内陆地区显著为负。(3)环境规制对高搬迁成本行业的技术创新作用在沿海地区显著为正,在内陆地区显著为负。     

国防科技工业军民融合资源效率风险研究

效率可分为价值形态效率和非价值形态效率,研究军民融合效率必须从非价值角度或从投入品和产出品价格相对不变情况下的价值角度出发。对国防科技工业军民融合效率风险相关概念、根源等基本问题进行界定,从竞争与垄断、生产规模、分工、多元化等四个方面分析了军民融合资源效率风险的关系和发生机理。为了规避军民融合资源效率风险,需遵循军民融合发展规律,健全融合管理机制,净化军民市场环境。     

Understanding the topic evolution of scientific literatures like an evolving city: Using Google Word2Vec model and spatial autocorrelation analysis

Topic evolution has been described by many approaches from a macro level to a detail level, by extracting topic dynamics from text in literature and other media types. However, why the evolution happens is less studied. In this paper, we focus on whether and how the keyword semantics can invoke or affect the topic evolution. We assume that the semantic relatedness among the keywords can affect topic popularity during literature surveying and citing process, thus invoking evolution. However, the assumption is needed to be confirmed in an approach that fully considers the semantic interactions among topics. Traditional topic evolution analyses in scientometric domains cannot provide such support because of using limited semantic meanings. To address this problem, we apply the Google Word2Vec, a deep learning language model, to enhance the keywords with more complete semantic information. We further develop the semantic space as an urban geographic space. We analyze the topic evolution geographically using the measures of spatial autocorrelation, as if keywords are the changing lands in an evolving city. The keyword citations (keyword citation counts one when the paper containing this keyword obtains a citation) are used as an indicator of keyword popularity. Using the bibliographical datasets of the geographical natural hazard field, experimental results demonstrate that in some local areas, the popularity of keywords is affecting that of the surrounding keywords. However, there are no significant impacts on the evolution of all keywords. The spatial autocorrelation analysis identifies the interaction patterns (including High-High leading, High-Low suppressing) among the keywords in local areas. This approach can be regarded as an analyzing framework borrowed from geospatial modeling. Moreover, the prediction results in local areas are demonstrated to be more accurate if considering the spatial autocorrelations.

User community vs. producer innovation development efficiency: A first empirical study

In this paper we report upon a first empirical exploration of the relative efficiency of innovation development by product users vs. product producers. In a study of over 50 years of product innovation in the whitewater kayaking field, we find users in aggregate were approximately 3× more efficient at developing important kayaking product innovations than were producers in aggregate. We speculate that this result is driven by what we term “efficiencies of scope” in problem-solving. These can favor an aggregation of many user innovators, each spending a little, over fewer producer innovators benefitting from higher economies of scale in product development. We also note that the present study explores only one initial point on what is likely to be a complex efficiency landscape.
