The rapid advancement of Chinese complex products and systems (CoPSs) enterprises marks their transition into a post-catch-up phase, challenging the conventional theories of catch-up. In this article, we employ a configurational approach to explore the intricate relationships between catch-up environments and strategies, specifically focusing on the distinct paths of state-owned enterprises (SOEs) and non-state-owned enterprises (non-SOEs) within the CoPS sector. Utilizing fuzzy-set qualitative comparative analysis with data sourced from the EU industrial research and development (R&D) investment scoreboard (2017–2020) and corresponding Chinese-listed companies, our research identifies diverse catch-up configurations for SOEs, characterized by “complexity adoption” and “complexity decipher” models. In contrast, non-SOEs encounter challenges in strategically adapting to environmental shifts, which affects their catch-up strategies. Our findings emphasize the critical role of strategic alignment with external conditions, technological learning, and resource utilization in achieving successful catch-up in CoPS. These configurations enable SOEs to effectively align internal resources with external opportunities, resulting in superior catch-up performance. In contrast, non-SOEs encounter significant obstacles in adapting to environmental changes and optimizing resource utilization, which hinders their ability to attain similar successes. Moreover, our study sheds light on specific challenges faced by non-SOEs in responding to environmental shifts. This enriched understanding provides valuable theoretical insights into the catch-up of latecomer CoPS enterprises and has practical implications for both policymakers and business practitioners.
中国复杂产品与系统(CoPSs)企业的快速发展标志着它们进入了后追赶阶段,这对传统的追赶理论提出了挑战。在本文中,我们采用了一种构型方法来探讨赶超环境与战略之间错综复杂的关系,尤其关注国有企业(SOE)和非国有企业(Non-SOE)在CoPS领域的不同发展路径。我们的研究利用模糊集定性比较分析和欧盟工业研发(R&D)投资记分牌(2017-2020年)及相应中国上市公司的数据,确定了国有企业的不同追赶配置,其特点是 "复杂性采纳 "和 "复杂性破解 "模式。相比之下,非国有企业在战略适应环境变化方面遇到了挑战,这影响了它们的赶超战略。我们的研究结果强调了战略调整与外部条件、技术学习和资源利用在实现 CoPS 成功赶超中的关键作用。这些配置使国有企业能够有效地将内部资源与外部机会结合起来,从而取得优异的赶超绩效。相比之下,非国有企业在适应环境变化和优化资源利用方面遇到了巨大障碍,这阻碍了它们取得类似的成功。此外,我们的研究还揭示了非国有企业在应对环境变化时所面临的具体挑战。这种丰富的认识为后发 CoPS 企业的赶超提供了宝贵的理论见解,并对政策制定者和企业从业者具有现实意义。

This article explores the imperative role of responsible innovation (RI) in guiding the development and integration of emerging technologies within society. With technological progress rapidly advancing, it becomes ever more imperative to confront the complex ethical, social, economic, and environmental challenges that accompany these innovations. This research highlights the significance of RI practices, advocating for a principle-based approach to technology development. It asserts that such an approach, which is rooted in societal values and ethical standards, is crucial for nurturing long-term societal well-being and fostering trust in new technologies, as opposed to relying solely on rule-based technology development governed by regulations. Our analysis begins with the definition of each RI principle, followed by an exploration of its relevance in addressing innovation dilemmas. Our case studies involve various sectors, including artificial intelligence, connected autonomous vehicles, and quantum computing, to showcase the practical application of these principles in real-world contexts. Through these instances, we highlight the efficacy of RI in both mitigating risks and maximizing the benefits of new technologies. In addition, the article investigates the dynamics of implementing RI within organizational frameworks and innovation processes. It provides strategic recommendations for technology managers and policymakers on how to operationalize RI principles effectively, emphasizing the need for an adaptive approach that is responsive to the rapid changes in the technology landscape. The study contributes to the academic discourse by highlighting that proactive engagement with RI can lead to more sustainable and socially acceptable technology outcomes. Ultimately, this research underscores the importance of responsible practices in innovation, proposing that a principled approach to technology development is essential for fostering long-term societal well-being and trust in new technologies.
本文探讨了负责任创新(RI)在指导新兴技术在社会中的发展和整合中的重要作用。随着技术进步的迅速推进,面对伴随这些创新而来的复杂的伦理、社会、经济和环境挑战变得越来越迫切。这项研究强调了国际扶轮实践的重要性,提倡以原则为基础的技术发展方法。它断言,这种根植于社会价值观和道德标准的方法,对于培育长期的社会福祉和培养对新技术的信任至关重要,而不是仅仅依靠基于规则的、受法规支配的技术开发。我们的分析从每项国际创新原则的定义开始,然后探索其在解决创新困境中的相关性。我们的案例研究涉及各个领域,包括人工智能、联网自动驾驶汽车和量子计算,以展示这些原则在现实环境中的实际应用。通过这些实例,我们强调了RI在降低风险和最大化新技术收益方面的功效。此外,本文还研究了在组织框架和创新过程中实施RI的动态。它为技术管理人员和政策制定者提供了关于如何有效地实施RI原则的战略建议,强调需要一种适应技术前景快速变化的适应性方法。该研究通过强调与国际扶轮的积极参与可以导致更可持续和社会可接受的技术成果,为学术论述做出了贡献。最后,这项研究强调了负责任的创新实践的重要性,提出了一种有原则的技术开发方法对于促进长期的社会福祉和对新技术的信任至关重要。

In this article, we aim to rank barriers hindering clean energy adoption within the healthcare industry by proposing a new framework with q-rung orthopair fuzzy data (q-ROFD). Energy is paramount in health industry, and it is estimated by the World Health Organization that nearly a billion people are treated globally with limited/no electricity. United Nation strongly recommends cutting dependencies on fossil fuels, but to meet demand, clean energy is focused. Studies on clean energies reveal that direct adoption is tough, owing to diverse barriers and ranking these barriers will provide policymakers clarity on the strategic plans. Existing studies reveal gaps in uncertainty modeling by not adequately exploring orthopair variants, human intervention reduction by failing to methodically determine diverse decision parameters, consideration of subjective attitude and interactions among entities that are essential for experts and attributes, and accounting for attribute type and yielding ranks comparable with a human decision. Motivated by the gaps, in this article, a combined q-ROFD model is presented where weights of attributes are determined via criteria importance through intercriteria correlation and rank sum and experts’ weights are obtained by rank sum. A ranking algorithm is developed with CODAS formulation for determining the barriers’ grades with risk aversion trait. The significance of the study lies in rational ranking of barriers, reduced human intervention, and methodical determination of decision parameters. The usefulness of the model is testified via a case study of barrier ranking within the Indian healthcare industry and comparison/sensitivity studies reveal the pros and cons of the developed model.
在本文中,我们旨在通过提出一个采用 q-rung orthopair 模糊数据(q-ROFD)的新框架,对阻碍医疗保健行业采用清洁能源的障碍进行排序。能源在医疗行业中至关重要,据世界卫生组织估计,全球有近十亿人在用电有限或无电的情况下接受治疗。联合国强烈建议减少对化石燃料的依赖,但为了满足需求,清洁能源是重点。有关清洁能源的研究表明,由于存在各种障碍,直接采用清洁能源非常困难。现有研究揭示了在不确定性建模方面存在的差距,如未充分探索正交模型的变体、未有条不紊地确定各种决策参数以减少人为干预、未考虑对专家和属性至关重要的主观态度和实体间的相互作用,以及未考虑属性类型并得出与人为决策相当的等级。鉴于上述不足,本文提出了一种组合式 q-ROFD 模型,其中属性权重通过标准间相关性和等级总和的标准重要性确定,专家权重则通过等级总和获得。利用 CODAS 公式开发了一种排序算法,用于确定具有风险规避特征的障碍等级。该研究的意义在于对障碍进行合理排序,减少人为干预,并有条不紊地确定决策参数。该模型的实用性通过印度医疗保健行业的障碍排序案例研究得到了验证,对比/敏感性研究揭示了所开发模型的优缺点。

The Internet of Things presents a significant economic value potential, where sensors play a crucial role in its infrastructure. However, the restricted electricity of sensors limits the lifespan of the entire network. The development of modern charging technology has made it possible to realize simultaneous one-to-many charging using drones. To make better use of this charging technology, this article investigates the problem of charging sensors by drones in three-dimensional (3-D) space. Differing from the existing literature, the 3-D hovering location of the drone affects the number of sensors being charged simultaneously and consequently the service time of charging. Additionally, we consider the scenario where multiple drones serve sensors in the same area, necessitating the assurance of continuous charging services. We propose a mixed integer formulation model to minimize the total cost of completing the recharging task. To solve this problem, an improved genetic algorithm is developed. Extensive experiments are conducted to show the superiority of our proposed method, the effect of one-to-many wireless charging mode, and the sensitivities of the results to the parameters including charging radius and wind scale. This article contributes to further insights into the optimization of wireless charging strategies for sensor networks and other similar problems.
物联网具有巨大的经济价值潜力,传感器在其基础设施中发挥着至关重要的作用。然而,传感器有限的电力限制了整个网络的使用寿命。现代充电技术的发展,使得利用无人机实现一对多同时充电成为可能。为了更好地利用这种充电技术,本文研究了无人机在三维空间中对传感器进行充电的问题。与已有文献不同的是,无人机的三维悬停位置会影响同时充电的传感器数量,从而影响充电的使用时间。此外,我们还考虑了多架无人机在同一区域为传感器服务的情况,这就需要保证持续的充电服务。我们提出了一个混合整数公式模型,以最小化完成充电任务的总成本。为了解决这一问题,提出了一种改进的遗传算法。通过大量的实验验证了所提方法的优越性、一对多无线充电模式的效果以及结果对充电半径、风标等参数的敏感性。本文有助于进一步了解传感器网络无线充电策略的优化以及其他类似问题。

As small and medium-sized enterprises (SMEs) struggle to adopt digital technologies, open innovation could provide a solution by utilizing external and internal technological resources across organizational boundaries to help SMEs overcome digital transformation deficits. This research investigates the direct effect of two open innovation strategies, namely, external technology acquisition and external technology exploitation, on digital transformation of emerging-market SMEs. It also examines how firm age and size moderate such effect. Analyses of 320 dual-source (one general manager and one production manager), time-lagged data from 160 Thai electronics SMEs suggest that external technology acquisition and external technology exploitation positively affect digital transformation. Moreover, as SMEs age, the positive effect of external technology acquisition and external technology exploitation on digital transformation becomes weaker and stronger, respectively. Furthermore, the positive effect of external technology exploitation on digital transformation appears to be stronger for larger SMEs than for smaller ones. The findings suggest that, to achieve digital transformation, early-stage SMEs’ managers should practice external technology acquisition; once SMEs mature, they should engage more in external technology exploitation. Likewise, as firm size does not moderate the effect of external technology acquisition on digital transformation, even small SMEs can attain digital transformation by effectively acquiring external technology.
由于中小型企业(SMEs)难以采用数字技术,开放式创新可以通过跨组织边界利用外部和内部技术资源来提供解决方案,帮助中小企业克服数字化转型赤字。本研究考察了外部技术获取和外部技术开发两种开放式创新策略对新兴市场中小企业数字化转型的直接影响。它还考察了公司的年龄和规模如何调节这种影响。对来自160家泰国电子中小企业的320个双源(一个总经理和一个生产经理)滞后数据的分析表明,外部技术获取和外部技术开发对数字化转型有积极影响。此外,随着中小企业年龄的增长,外部技术获取和外部技术开发对数字化转型的积极作用分别减弱和增强。此外,外部技术开发对大型中小企业数字化转型的积极影响似乎比小型中小企业更强。研究结果表明,为实现数字化转型,早期中小企业管理者应进行外部技术获取;中小企业一旦成熟,就应该更多地参与外部技术开发。同样,由于企业规模不调节外部技术获取对数字化转型的影响,即使是小企业也可以通过有效获取外部技术来实现数字化转型。

We first used text analysis methods to define and measure the level of data element input. We qualitatively demonstrated that data element input can improve total factor productivity (TFP) by constructing a new classical economic growth model by adding data elements. On this basis, we built a translog stochastic frontier model to incorporate data elements into the production function and TFP measurement model. Using data from Chinese manufacturing listed companies from 2010 to 2023, we quantitatively measured and dynamically evaluated the impact of data element input on manufacturing TFP and the role of technical efficiency and technological progress. The results revealed the following: 1) Data element input as a whole is beneficial for improving manufacturing TFP, but the main path is the improvement of technical efficiency. Additionally, data processing and application significantly improve TFP, whereas data acquisition does not. 2) The impact of digitalization on the current industrial structure has not affected technological progress, but it has restricted improvements in technical efficiency. Data elements are increasingly becoming the critical material basis for the manufacturing industry's digital transformation. In this context, this study has the following practical value: 1) It helps better identify the critical path of data elements to empower manufacturing industry TFP to implement more targeted digital transformation in practice; and 2) it contributes to a more comprehensive understanding of the impact of digitalization on the manufacturing industry structure to fully leverage the positive role of data elements in enhancing enterprise productivity.
我们首先使用文本分析方法来定义和衡量数据元素的输入水平。通过加入数据元素构建新的经典经济增长模型,我们定性地证明了数据元素的投入可以提高全要素生产率(TFP)。在此基础上,我们建立了一个 translog 随机前沿模型,将数据要素纳入生产函数和全要素生产率测算模型。利用 2010 年至 2023 年中国制造业上市公司的数据,定量测算并动态评估了数据要素输入对制造业全要素生产率的影响,以及技术效率和技术进步的作用。结果表明1)数据要素投入整体上有利于提高制造业全要素生产率,但主要途径是提高技术效率。此外,数据处理和应用能显著提高全要素生产率,而数据获取则不然。2)数字化对当前产业结构的影响并没有影响技术进步,但却限制了技术效率的提高。数据要素日益成为制造业数字化转型的重要物质基础。在此背景下,本研究具有以下实践价值:1)有助于更好地明确数据要素赋能制造业全要素生产率的关键路径,在实践中更有针对性地实施数字化转型;2)有助于更全面地认识数字化对制造业产业结构的影响,充分发挥数据要素在提升企业生产率方面的积极作用。

A Taxonomy-Based Data Model for Assessing Engineering Skills in an Organizational Context 基于分类标准的数据模型,用于评估组织背景下的工程技能

A taxonomy-based data model is proposed to create a knowledge system for managing engineering skills within an organization, motivated by the need to balance organizational expertise requirements and availability. The model, adapted from the “European Skills, Competences, Qualifications, and Occupations” framework, is designed to categorize and evaluate skills relevant to the engineering department of the National Physical Laboratory. This allows extraction of quantitative data on individual staff members' skills and competency levels, and the necessary skills for specific Job Title and Job Role combinations. It distinguishes between “Job Titles,” official job designations, and “Job Roles,” unofficial designations categorizing staff according to their work areas, allowing the model to conform with inherent organizational rigiditiy. The model can cross-reference information using specific queries, such as extracting skills from specific individuals and assessing if they meet their current job functions. This model enhances existing skill management frameworks by allowing for a traceable pathway for skill allocation, allowing for future expansion by including other departments.

出于平衡组织专业知识需求和可用性的需要,我们提出了一个基于分类法的数据模型,以创建一个知识系统,用于管理组织内的工程技能。该模型改编自 "欧洲技能、能力、资格和职业 "框架,旨在对国家物理实验室工程部门的相关技能进行分类和评估。这样就可以提取有关工作人员个人技能和能力水平的量化数据,以及特定工作头衔和工作角色组合所需的技能。它区分了 "职位名称 "和 "工作角色","职位名称 "是正式的职位名称,而 "工作角色 "则是根据工作领域对员工进行分类的非官方名称,从而使模型符合固有的组织刚性。该模型可通过特定查询对信息进行交叉引用,例如从特定个人身上提取技能,并评估这些技能是否符合其当前的工作职能。该模型可为技能分配提供可追溯的途径,从而增强现有的技能管理框架,并可在未来扩展到其他部门。还可以考虑整合评估员工技能的验证程序,如将证明附在技能上。该模型还能带来业务效益,如加强能力规划、促进员工发展、优化资源分配和改进培训计划。

This allows extraction of quantitative data on individual staff members' skills and competency levels, and the necessary skills for specific Job Title and Job Role combinations. It distinguishes between “Job Titles,” official job designations, and “Job Roles,” unofficial designations categorizing staff according to their work areas, allowing the model to conform with inherent organizational rigiditiy. The model can cross-reference information using specific queries, such as extracting skills from specific individuals and assessing if they meet their current job functions.

Digital management system is widely used in the business activities of enterprises. Practice has proved that the implementation of the manufacturing execution system (MES) can better monitor and manage the production process, improve the production efficiency of enterprises, and effectively realize zero defect management (ZDM). Against this background, the influencing factors of implementing MES in ZDM enterprises in digital transformation were obtained by using the literature extraction-Delphi method, and the relationship between the factors was analyzed by using the system dynamics simulation model in this study. It is found that different from the existing research works on the implementation of MES in enterprises, staff preparation and level of information sharing are the most influential factors and play an important role in the implementation of MES in ZDM enterprises. Equipment preparation and client preparation followed closely, with supplier implementation team and scale infrastructure conditions playing a key role in providing capability support. This finding provides the direction for enterprises to improve the relevant implementation measures in time to ensure the effective implementation of MES in ZDM enterprises, and also provides a breakthrough for relevant researchers to find valuable research fields.

This article anchors itself in knowledge network theory and rivalry theory to explore the antecedents of exploration by examining the possibility of technological crowding, that is, a firm position in crowded technological fields, as the enabler of firms’ exploratory innovation performance. For this purpose, we adopted regression analysis for panel data with fixed effects and considered the data of 4100 firm-year observations of Taiwanese listed companies in the electronics industry from 2000 to 2021. The findings suggest that technological crowding urges firms to pursue exploration to ease heightened competition intensity and crowd out their competitors. Recalling the literature on the competency trap phenomenon in which some dominant firms may exhibit technological superiority underperformance, we further propose that the dark side of technological superiority is more visible when firms are positioned in crowded technological areas. Specifically, firms with stronger combinatorial capabilities or greater technological prestige refrain from investing in exploration because they are tied with high couplings between their homogeneous knowledge elements and indulge themselves in existing success. Our findings remain robust after adjusting the window of research and using the negative binomial regression with fixed effects based on the alternative measure of exploratory innovation. This article contributes significantly to the literature on technological position and knowledge networks by shedding light on the critical role of technological crowding in propelling firms’ exploration efforts. Our results also offer significant implications for executives in dominant firms and policymakers to become more aware of the competency trap and seek ways to span technological boundaries.
本文立足于知识网络理论和竞争理论,通过研究技术拥挤(即企业在拥挤的技术领域中的地位)作为企业探索性创新绩效的促进因素的可能性,来探讨探索性创新的前因。为此,我们采用了固定效应的面板数据回归分析,并考虑了 2000 年至 2021 年台湾电子行业上市公司的 4100 个公司年观测数据。研究结果表明,技术挤占促使企业进行探索,以缓解竞争强度的提高并排挤竞争对手。回顾有关 "能力陷阱"(competency trap)现象的文献,其中一些占主导地位的企业可能会表现出技术优势表现不佳,我们进一步提出,当企业处于拥挤的技术领域时,技术优势的阴暗面会更加明显。具体来说,具有更强组合能力或更高技术声望的企业会因为同质知识要素之间的高度耦合而放弃投资探索,并沉溺于已有的成功。在调整研究窗口和使用基于探索性创新替代衡量标准的固定效应负二项回归后,我们的研究结果依然稳健。本文揭示了技术挤占在推动企业探索努力中的关键作用,为有关技术地位和知识网络的文献做出了重要贡献。我们的研究结果还为主导企业的高管和政策制定者提供了重要启示,使他们更加意识到能力陷阱,并寻求跨越技术边界的方法。
