Introduction Over the past decade, artificial intelligence (AI) has emerged as a pivotal force reshaping the global industrial landscape. In sectors such as finance, healthcare, and logistics, AI has been widely acknowledged as a catalyst for efficiency gains and new service models [1, 2]. Among various manufacturing industries, the automotive sector stands out owing to its high capital intensity, complex supply chains, and the strategic importance of continuous product and process innovation. Traditional automotive manufacturing has historically relied on large-scale assembly lines, rigid production systems, and standardized modules [3]. While these practices have driven economies of scale, they have also engendered inflexibility and limited responsiveness to rapidly changing consumer preferences and regulatory requirements. Recent market pressures—such as the global shift toward electrification, increased regulatory stringency on emissions, and rising consumer demand for personalization—have compelled automotive manufacturers to pursue innovation across products, processes, and business models [4, 5]. Simultaneously, digital technologies have begun to permeate manufacturing operations. Despite these sporadic advances, a unified, process-oriented framework explaining how AI fosters innovation upgrades in automotive manufacturing— and how it influences inter-enterprise collaboration within the automotive industry value chain—remains underdeveloped. Many extant studies on AI in automotive contexts tend to focus on autonomous driving, predictive maintenance, or logistic optimization [6, 7]. Less attention has been paid to the systematic integration of AI into core manufacturing processes (i.e., stamping, welding, painting, assembly) and its impact on both firm-level and supply-chain-level innovation outcomes [8]. Moreover, while scholars acknowledge that data sharing and digital platforms could enable industry-wide collaboration [9, 10], empirical evidence on how AI specifically catalyzes cross-organizational innovation in an automotive ecosystem is limited, particularly within emerging markets such as China. This paper aims to fill these gaps by (1) developing a comprehensive theoretical framework that articulates the pathways through which AI drives innovation upgrades in automotive manufacturing, (2) empirically testing that framework via a mixed-methods approach grounded in questionnaire surveys and case studies of Chinese automotive manufacturers, and (3) deriving actionable insights for managers and policymakers on how to effectively leverage AI for both process innovation and inter-enterprise collaboration. 2. Literature Review 2.1. AI Applications in Manufacturing In manufacturing, AI applications can be categorized into four primary domains: (1) Production Planning and Scheduling. (2) Quality Control and Inspection. (3) Predictive Maintenance. (4) Flexible Automation and Robotics. While these studies illustrate discrete AI applications, they often lack a process- centric perspective that examines how AI transforms the entire manufacturing workflow from resource acquisition to final assembly. Additionally, most research investigates single technologies in isolation rather than exploring how integrated AI systems can drive systemic innovation across multiple manufacturing functions [11, 12]. 2.2. Automotive Industry Innovation Innovation in the automotive sector encompasses product innovation (e.g., electric vehicles, connected cars), process 12 innovation (e.g., lean manufacturing, modular assembly), and business model innovation (e.g., mobility-as-a-service) [4, 13]. Traditionally, leading automakers relied on incremental process improvements—such as just-in-time production—to drive competitiveness [14]. More recently, digital disruptions have triggered new forms of innovation. Although scholars recognize AI as a driver of smart manufacturing, empirical research on the direct relationship between AI adoption and manufacturing innovation performance remains sparse [15]. Moreover, most studies focus on developed economies; there is a dearth of empirical evidence from emerging markets such as China, where industry ecosystems, regulatory environments, and talent pools differ significantly [16]. 2.3. Inter-Enterprise Collaboration and Innovation Performance Innovation in complex industries like automotive often requires collaboration among multiple stakeholders—OEMs, first-tier and second-tier suppliers, technology vendors, and research institutes [17, 18]. The concept of “innovation ecosystems” emphasizes how digital platforms can integrate diverse actors, enabling knowledge spillovers and co-creation [19]. Studies have demonstrated that collaborative innovation networks yield higher R\&D productivity and faster time-to- market in automotive settings. However, the role of AI as an enabling technology for such collaboration is underexplored. Specifically, questions remain regarding how AI-mediated platforms influence trust, knowledge sharing, and co- innovation outcomes across geographically dispersed supply chains. 3. Research Methods 3.1. Theoretical Models and Hypotheses We have constructed a research model to explore the role of AI in manufacturing process optimization and inter- enterprise collaboration, and further analyze its impact on manufacturing innovation performance (including incremental and breakthrough innovations). The model includes four core variables: AI application, process innovation, collaborative cooperation and innovation performance, and five research hypotheses are set to verify the path relationship among them. 3.2. Research Design Adopt a mixed approach, including: Questionnaire survey: Targeting technical and management personnel in China's automotive manufacturing enterprises, collect data related to the current status of AI application, process innovation, enterprise collaboration and innovation achievements. Case Study: In-depth interviews with representative enterprises such as BYD, NIO, and Great Wall Motor, as well as suppliers like Bosch and Continental, to analyze the effectiveness and implementation difficulties of AI applications. 3.3. Questionnaire Data A total of 236 valid questionnaires were retrieved, covering vehicle manufacturers, Tier 1 suppliers and AI technology service providers. All the measured indicators were measured using a five- point scale, focusing on dimensions such as the degree of AI application, process optimization and improvement, cross- enterprise data sharing and collaboration, as well as innovation achievements. The results of the reliability and validity analysis show that the measurement tools for all variables have good consistency and discrimination. 3.4. Case Analysis Five representative enterprises were selected for interviews and document analysis. By summarizing the typical experiences of enterprises in the process of AI application, verify the findings of the questionnaire survey and supplement the situational details. 4. Results 4.1. Descriptive Statistics and Correlations Table1 presents means, standard deviations, and inter- construct Pearson correlations. Table 1.

These correlations demonstrate significant positive relationships among key constructs, supporting preliminary hypotheses that AI adoption relates to process innovation, collaboration, and innovation performance. 4.2. Hypothesis Testing The research hypotheses were verified by using the Structural Equation Model (SEM), and the model fit well: AI applications have a significant positive impact on process innovation (β=0.58) and enterprise collaboration (β=0.51). Process innovation and collaboration have significant positive impacts on both incremental and breakthrough innovations in innovation performance respectively. The mediating effect analysis shows that process innovation and collaboration play a key mediating role in the path of AI influencing innovation performance. 13 4.3. Case Verification Byd: The AI system reduces the welding defect rate and saves the average annual cost. The data platform promotes collaboration with battery suppliers. Nio: Digital Twin system Optimizes Assembly process; AI collaborative robots enhance the efficiency of battery assembly. Great Wall Motor: AI detection improves the yield rate of paint processes; It is still in the partial pilot stage and the data integration is limited. Bosch China: Providing learnable robots and industrial platforms to help multiple Oems achieve cross-factory data benchmarking. These cases further confirm the positive role of AI in optimizing manufacturing processes and promoting collaborative innovation, while also revealing practical challenges such as data silos and talent shortages. 4.4. Synthesis of Quantitative and Qualitative Findings By triangulating survey and case results, we derive the following key insights: (1) AI’s Direct Impact on Process Innovation. Quantitative data show strong correlations between AI adoption and process innovation (β = 0.58, p < 0.001), corroborated by qualitative evidence from BYD and NIO where AI systems significantly improved stamping precision and production flexibility. (2) Collaboration as a Mediator. Inter-enterprise collaboration mediates 29% of AI’s effect on incremental innovation. Cases from BYD and Bosch illustrate that integrated data platforms accelerate joint problem solving, thereby amplifying innovation beyond firm boundaries. (3) Organizational Enablers’ Importance. Both top- management support and employee digital competencies strengthen AI’s impact. BYD’s CEO sponsorship and NIO’s talent recruitment strategies exemplify how leadership commitment and digital skills boost AI effectiveness. (4) Barriers and Challenges. Common obstacles include data silos (GWM), cybersecurity concerns (GWM), talent shortages (NIO), and high implementation costs (Bosch IaaS subscriptions). Overcoming these requires both technical solutions (e.g., standardized data architectures) and supportive policies (e.g., AI talent incentives). 5. Discussion 5.1. Theoretical Contributions This study extends prior literature in three main ways: (1) Integrated Process-Ecosystem Perspective. Unlike earlier research that treats AI applications in silos (e.g., only quality inspection or predictive maintenance), we develop and empirically validate a comprehensive framework linking AI, process innovation, and inter-enterprise collaboration. This holistic viewpoint elucidates how synergy between internal process improvements and external collaboration amplifies innovation. (2) Evidence from an Emerging Market Context. While most innovation management studies focus on Western economies [15], our research provides empirical data from Chinese automotive manufacturers, enriching cross-cultural understanding of AI’s role in manufacturing. (3) Moderating Role of Organizational Enablers. By demonstrating that top-management support and employee digital competencies significantly moderate AI’s impact, we contribute to the literature on technology implementation and organizational change [20]. 5.2. Managerial Implications Our findings offer several actionable insights for practitioners: (1) Cultivate Leadership Commitment. Firms embarking on AI transformation should secure unwavering backing from top management. Senior executives must allocate sufficient budgets, champion cross-functional teams, and actively communicate the strategic importance of AI. (2) Invest in Workforce Digital Upskilling. Human capital remains a critical enabler. Organizations should implement comprehensive training programs (e.g., workshops on data analytics, AI tool usage) and collaborate with universities to develop specialized curricula. (3) Build Integrated Data Platforms. To realize the full benefits of AI, manufacturers must break down data silos by consolidating disparate ERP, MES, and IoT systems into unified, cloud-based platforms. Standardized data protocols (e.g., OPC UA, MQTT) facilitate interoperability with suppliers. (4) Foster Collaborative Ecosystems. OEMs should proactively invite tier-1 and tier-2 suppliers to share production and quality data. Joint analytics workshops can help partners co-identify root causes of defects or downtime, leading to faster cycle-time reductions. (5) Address Cybersecurity and Data Governance. With increased data sharing comes greater cybersecurity risk. Establish robust governance frameworks—including access controls, encryption standards, and incident response plans— to build trust among ecosystem partners. 5.3. Policy Implications Given the strategic significance of the automotive sector and AI’s potential for economic growth, policymakers should: (1) Provide Incentives for AI-Driven Transformation. Tax credits, low-interest loans, and subsidies for AI infrastructure investments can lower entry barriers for small and medium- sized automotive firms. (2) Support Industry-Academia Collaboration. Government grants for joint research between universities, research institutes, and automotive firms can accelerate AI innovation and talent cultivation. (3) Establish Data-Sharing Standards. National or industry associations can lead the development of standardized data formats and interoperability guidelines to facilitate cross- enterprise collaboration. (4) Promote Workforce Development Programs. Subsidize vocational training and certification programs focused on AI, data analytics, and advanced robotics to address talent shortages. 5.4. Limitations and Future Research While this study provides novel insights, it has limitations: (1) Cross-Sectional Design. Our survey captures a single time point; longitudinal research could better assess causal dynamics and long-term innovation trajectories. (2) Geographical Focus. Although China represents a major portion of the global automotive industry, findings may not generalize to regions with different regulatory or cultural environments. Future comparative studies across countries 14 could yield richer insights. (3) Scope of AI Applications. We concentrated primarily on manufacturing process applications. Subsequent research might incorporate AI in product design (e.g., generative design), after-sales services (e.g., AI chatbots), or end-of-life recycling. 6. Conclusion This paper investigates how artificial intelligence can empower innovation upgrades in the automotive manufacturing industry, focusing on both process-level improvements and inter-enterprise collaboration. Through a mixed-methods approach—combining a quantitative survey of 236 Chinese automotive firms with qualitative case studies of industry leaders—our findings confirm that: (1) AI Adoption Drives Process Innovation. Firms that implement AI in production planning, quality control, and predictive maintenance consistently report significant gains in manufacturing efficiency, defect reduction, and flexible production capabilities. (2) Process Innovation Enhances Innovation Performance. Improvements in manufacturing processes translate into both incremental innovation (e.g., cost reductions, efficiency improvements) and breakthrough innovation (e.g., novel production methods). (3) AI Facilitates Inter-Enterprise Collaboration.AI-driven data platforms foster data sharing and coordinated problem- solving among OEMs and suppliers, thereby strengthening collaborative innovation across the automotive value chain. (4) Collaborated Innovation Mediates AI’s Impact. Collaboration accounts for a substantial portion of AI’s effect on innovation performance, indicating that ecosystem dynamics are key to maximizing AI benefits. (5) Organizational Enablers Are Critical. Top-management support and employee digital competencies significantly bolster AI’s effectiveness, underscoring the importance of leadership commitment and human capital development. For practitioners, the study highlights the need to holistically integrate AI into manufacturing workflows and supply-chain networks, invest in data-driven architectures, and build collaborative ecosystems. For policymakers, the research underscores the value of supporting AI infrastructure investments, fostering industry-academia partnerships, and standardizing data-sharing protocols. As the automotive industry undergoes profound digital transformation—driven by electrification, connectivity, and AI—the capacity to harness AI for manufacturing innovation will determine competitive advantage. This paper provides a robust framework and empirical evidence that can guide stakeholders toward a more intelligent, collaborative, and innovative automotive future.
