平台与互补商协同创新的制度逻辑及其作用机制

平台与互补商的协同专业化对于创新生态系统的构建具有重要作用.然而,平台企业与互补商可能各自具有冲突的或互补的制度逻辑,它们彼此要实现协同创新的目标,就必然在达成协作共识的过程中形成主导型制度逻辑,进而规范双方的创新活动与行为.但是,这种主导型制度逻辑如何产生?它们的作用机制是什么?过去的研究还很少涉及这类问题.本文通过OPPO的案例研究,结果表明:(1)平台与一般互补商合作时,平台的谈判能力相对较强,平台的制度逻辑占据主导地位;(2)平台对瓶颈互补商具有较强的依赖时,互补商拥有较强的谈判能力,平台在两者的合作中会选择妥协,此时互补商的制度逻辑占主导地位;(3)平台与瓶颈互补商的关系是双向依赖时,两方合作形成的制度逻辑是混合逻辑;(4)面对强大的外部制度压力时,平台与互补商的合作会形成或遵循新的制度逻辑.     

科技保险的困境—一个制度供求非均衡分析

现阶段，我国步入了创新驱动引领升级的关键时期，科技创新受到了整个社会的空前重视。科技保险作为分散和转移科技风险的重要手段，可以为科技创新提供有力的风险保障。目前，我国科技保险工作已经进入全面推广阶段，虽然取得了一定的成效，但整体运行并不理想，科技企业参保率低，科技保险缺失严重。究其原因，主要在于制度供给不能适应科技企业对科技保险的需求，科技保险制度供求非均衡，在现行的科技保险制度下积聚着大量的潜在利润，而这些潜在利润既是科技保险制度非均衡的原因，又是科技保险制度创新的动力。     

Design selection for strong orthogonal arrays

Strong orthogonal arrays (SOAs) were recently introduced and studied as a class of space‐filling designs for computer experiments. An important problem that has not been addressed in the literature is that of design selection for such arrays. In this article, we conduct a systematic investigation into this problem, and we focus on the most useful SOA(n,m,4,2 + )s and SOA(n,m,4,2)s. This article first addresses the problem of design selection for SOAs of strength 2+ by examining their three‐dimensional projections. Both theoretical and computational results are presented. When SOAs of strength 2+ do not exist, we formulate a general framework for the selection of SOAs of strength 2 by looking at their two‐dimensional projections. The approach is fruitful, as it is applicable when SOAs of strength 2+ do not exist and it gives rise to them when they do.

Copula‐based semiparametric analysis for time series data with detection limits

The analysis of time series data with detection limits is challenging due to the high‐dimensional integral involved in the likelihood. Existing methods are either computationally demanding or rely on restrictive parametric distributional assumptions. We propose a semiparametric approach, where the temporal dependence is captured by parametric copula, while the marginal distribution is estimated non‐parametrically. Utilizing the properties of copulas, we develop a new copula‐based sequential sampling algorithm, which provides a convenient way to calculate the censored likelihood. Even without full parametric distributional assumptions, the proposed method still allows us to efficiently compute the conditional quantiles of the censored response at a future time point, and thus construct both point and interval predictions. We establish the asymptotic properties of the proposed pseudo maximum likelihood estimator, and demonstrate through simulation and the analysis of a water quality data that the proposed method is more flexible and leads to more accurate predictions than Gaussian‐based methods for non‐normal data.

An additive–multiplicative mean model for panel count data with dependent observation and dropout processes

This paper discusses regression analysis of panel count data with dependent observation and dropout processes. For the problem, a general mean model is presented that can allow both additive and multiplicative effects of covariates on the underlying point process. In addition, the proportional rates model and the accelerated failure time model are employed to describe possible covariate effects on the observation process and the dropout or follow‐up process, respectively. For estimation of regression parameters, some estimating equation‐based procedures are developed and the asymptotic properties of the proposed estimators are established. In addition, a resampling approach is proposed for estimating a covariance matrix of the proposed estimator and a model checking procedure is also provided. Results from an extensive simulation study indicate that the proposed methodology works well for practical situations, and it is applied to a motivating set of real data.     

On the Changes of Modern Chinese Vocabulary: Taking"Nayun(拿云)"as an Example

"拿云"一词是近代汉语新产生的词汇,具有典型的动词性特点,其内部构造具有明显的动宾关系,可以充当定语、状语、宾语、谓语等成分.该词的语用风格具有典雅性,结构具有凝固性;其夸张义、比喻义也比较明显.该词的产生具有深厚的认知基础,具体表现为:基于隐喻的词义引申、语言的陌生化原则和基于构式"拿+X"的扩充."拿云"的词汇化始于语言的重新分析机制,历程是错综复杂的."拿云"的词汇化历程体现了部分近代汉语词汇的演变轨迹.     

CIO自身技能、需求方领导力与数字化创新

现有研究强调数字化创新对企业的战略价值,但学术界对企业如何进行数字化创新的认识却较为有限.借鉴变革型领导理论,本文提出CIO需求方领导力正向影响企业数字化创新水平,同时,CIO结构权力可以增强CIO需求方领导力与企业数字化创新水平的正向关系.此外,从CIO自身技能方面识别出CIO需求方领导力的三个重要前因:战略IT知识、政治悟性以及网络能力.通过采集179份CIO-TMT的企业配对问卷数据进行实证分析,实证结果较好地支持了研究假设.本文提出的假设模型为企业发挥CIO在推进数字化创新中的主导作用提供了理论基础和实践启示.     

从造字到造形：汉字形体结构与书法艺术

汉字作为一种书写形体，笔画组合的丰富多样和间架结构的灵活多变，而使其“字形”成为复杂的美学构成，“书写”成为“书法”，并完成从造字到造形的转变。书法是汉字书写艺术，书法艺术深藏于汉字独特的形体结构之中。三位一体的整体架构、二维方块结体、平衡对称等汉字在形体构造上的诗性特征，既是人们对文字形体的一种审美预期，也是书法学家在书法创作时努力追求的美感。     

What is this moment we are caught in?

Our response to the question ‘What is this moment we are caught in?' is articulated through our collaborative reading of Berlant's (2011) Cruel Optimism (Durham, NC: Duke University Press). Cruel optimism, Berlant suggests, is a desire for something that undermines its own potentiality. As queer academics we expose the cruelty of our desires to live a good academic life, and we do so from our different positions as postdoctoral fellow, tenured academic and PhD candidate. In labouring to consolidate relationships and practices that hold the promise of our own sustainability, we give accounts of the material and affective work we perform to constitute what Berlant calls an intimate public, a collective space of mediation that functions as a key tactic to manage our academic life. These accounts take the form of three vignettes, each inflected by the specificities of our different positions and histories of becoming academics. We use Berlant as a point of departure to both interrogate practices of self‐management and find possibilities for a collective response to the moments in which we find ourselves caught.
