In the era of digital economy，digital transformation has become an inevitable trajectory of enterprise development. From a supply chain perspective，the costumer digital transformation can exert substantial influences on supplier through supply chain channels. However，does the digital transformation of costumer affect the digital technological innovation of supplier? To address this question，this paper established an econometric model by matching the data among listed company on China' Shanghai and Shenzhen A-share market from 2011 to 2022. It empirically examined the spillover effects of costumer' digital transformation on supplier' digital technological innovation and its underlying mechanisms. The results indicated： （1） The digital transformation of costumer exerts a positive spillover effect on the digital technological innovation of supplier，a series of robustness tests and endogeneity discussions confirm the reliability of this conclusion；（2） The impact of customer companies' digital transformation on supplier companies' digital technological innovation is stronger when： the supplier and customer companies operate in the same industry，or the supplier companies' industry exhibits a high level of digital transformation；（3） the customer companies' digital transformation promotes supplier companies' digital technology innovation through two channels： information spillovers and supply-demand alignment. The intensity of cooperation and industry competition strength positively moderate these relationships. This study revealed the underlying mechanism of customer companies' digital transformation influencing supplier companies' digital technology innovation from a supply chain perspective，enriching the economic consequences of corporate digital transformation and providing theoretical support and decision-making references for advancing corporate digital technology innovation practices；（2） this effect is more pronounced when supplier and customer operate within the same industry or when supplier is located in highly digitized sectors；and （3） the customer digital transformation enhances supplier innovation through information spillovers and improved supply-demand alignment，with cooperative intensity and industry competition positively moderating these mechanisms. Overall，this study has elucidated the mechanisms through which customer digital transformation influences supplier digital technological innovation from a supply chain perspective. It has extended the literature on the economic consequences of enterprise digital transformation and will provide theoretical insights and policy implications for fostering digital technological innovation.

Government data opening is a necessary measure for the supply of data factors，and using government data opening to enhance urban entrepreneurial activeness is an important path and embodiment of releasing data dividends. In this paper，government data opening was used as a quasi-natural experiment，and the progressive double-difference method was used to test the impact of data factors supply on urban entrepreneurial activeness. It was found that the supply of data factors represented by government data opening can significantly improve the entrepreneurial activeness in cities. The mechanism analysis showed that government data opening enhances urban entrepreneurial activeness by promoting technological innovation，strengthening talent gathering and improving government administrative efficiency. The heterogeneity analysis showed that the promotion effect of government data opening on urban entrepreneurial activeness is more obvious in cities with higher financial development level，digital economy development level and economic development level，as well as producer services. Further analyses showed that there is a positive correlation between the open quality of government data and the entrepreneurial activeness in cities，and the open government data improves the entrepreneurial quality in cities. This paper will enrich the research on the economic effect of data factor supply and clarify the logical mechanism of government data opening to enhance urban entrepreneurial activeness，and provide theoretical basis and decision-making reference for enhancing the positive effect of government data opening on urban entrepreneurship.

The study of the impact of environmental regulations on green patent output has become a hot topic in academic research. The dual externalities in this impact process need to be addressed through the joint efforts of environmental regulations and intellectual property protection. Integrating environmental regulations，green patents，and intellectual property protection into a unified analytical framework is significant for exploring the effective solutions to environmental problems. This paper used the data from 11 provincial-level regions in the Yangtze River Economic Belt from 2010 to 2021 to examine the impact of environmental regulations on green patent output，and further analysed the moderating effect of intellectual property protection. The research found that： （1） there is a U-shaped relationship between environmental regulations and the quantity of green patent output；（2） Environmental regulations exhibit complex nonlinear characteristics on the quality of green patent output，and after crossing the inflection point of the U-shaped relationship，they can effectively improve the quality of green patent output；and （3） Intellectual property protection plays a significant positive regulatory role in the environmental regulation process affecting the quantity and quality of green patent output. This study has filled the gap in theoretical research on the impact of environmental regulations on green patent output，and will provide practical insights for balancing environmental protection and economic development in the Yangtze River Economic Belt.

Environmental supervision is an important part of government environmental governance and a key driving factor of green innovation. Based on the panel data of A-share listed companies in 120 major cities in China from 2008 to 2018，this paper examined the relationship between environmental supervision and corporate green innovation from the perspective of promotion pressure by using the fixed effect and moderating effect models. The study found that： （1） Environmental supervision only significantly promotes the quantity of corporate green innovation，rather than the quality，which induces the "bubble" phenomenon of green innovation；（2） The promotion pressure positively regulates the relationship between environmental supervision and the quantity of green innovation and enhances the "bubble" effect of environmental supervision；（3） The "bubble" phenomenon of green innovation caused by environmental supervision is concentrated in heavily polluting industries and eastern regions. It has a significant role in promoting the quality and quantity of green innovation in highly urbanized regions. However，the regulatory effect of promotion pressure is not effective；（4） Environmental supervision affects green innovation through industrial transfer，and causes neighboring areas to become "pollution havens". The central vertical supervision weakens the "bubble" phenomenon of green innovation. This paper has deepened the research scope and boundary conditions of macro-policy and micro-corporate innovation，which brings a new perspective and theoretical framework for existing research. It will also provide beneficial enlightenment and empirical evidence for optimizing environmental supervision policies and promoting corporate green transformation.

The effective response to the paradoxical and unified contradictions in enterprise digital innovation is not only the premise for comprehensive realization of digital innovation but also an important issue for the development of new quality productive forces driven by digital innovation. However，the academic community currently lacks a systematic review of this knowledge framework. This paper adopted a bibliometric and systematic review method，by screening 108 relevant papers from high-level domestic and international journals to organize the enterprise digital innovation paradox. It constructed a research framework of "concept classification-causes-performance-response mechanisms". The main conclusions are as follows： first，the concept of enterprise digital innovation paradox is defined，forming a three-dimensional classification system of digital technology innovation paradox，digital market innovation paradox，and digital organizational innovation paradox；second，the causes and manifestations of enterprise digital innovation paradox are summarized in the technical，market，and organizational levels；and third，19 mechanisms for coping with digital innovation paradoxes are summarized from seven theoretical perspectives： dynamic capabilities，modularity，optimal differentiation，institutional logic，data ethics，paradoxical leadership，and organizational ambidexterity. Finally，the paper has further proposed potential paradoxical issues that may arise in the future，aiming to provide a detailed theoretical basis and analytical tools for subsequent research.

The patent pledge financing policy is an important path to help enterprises to alleviate difficulties，which is of far-reaching significance for enterprises to optimize their asset structure and achieve high-quality development. However，there is a lack of research on the impact of patent pledge financing policies on the dynamic adjustment of corporate capital structure. This paper used a multi-period DID method to test the impact of patent pledge pilot policy on the dynamic adjustment of corporate capital structure based on the sample of China's A-share listed companies from 2001 to 2022. This paper found that the pilot policy of patent pledge can reduce the deviation of corporate capital structure. The mechanism analysis showed that the role of patent pledge pilot policy in reducing capital structure deviation is mainly achieved by alleviating financing constraints. The heterogeneity analysis showed that the reduction effect of patent pledge pilot policy on the deviation of corporate capital structure is more obvious in enterprises with non-state-owned nature，smaller scale and higher level of industry competition. From the perspective of adjustment speed，the patent pledge pilot policy can improve the speed of corporate capital structure adjustment；and after distinguishing the adjustment direction，it was found that the patent pledge pilot policy can not only improve the upward adjustment speed of corporate capital structure，but also improve the downward adjustment speed of corporate capital structure. From the perspective of adjustment methods，the patent pledge pilot policy mainly improves the speed of corporate capital structure adjustment through debt financing. This study will not only enrich the related research on the influencing factors of dynamic adjustment of enterprise capital structure and the economic effect of patent pledge policy，but also provide decision-making reference for further execution of the pilot work of patent pledge and optimization of the financing structure of enterprises.

Promoting the deep integration of S&T innovation and industrial innovation through an enterprise-led innovation consortium is the key to make breakthroughs in key core technologies and accelerate the development of new quality productive forces. Based on the evolutionary game theory，this paper used the Matlab software to simulate and analyze the strategy selection of innovation subjects under changes in different parameters，revealing the dynamic evolution law according to which the S&T leading enterprises lead innovation consortium to make continuous breakthroughs in key core technologies. The research found that： （1） The government's willingness of participation is a critical factor influencing the cooperation among the innovation consortium members，with a particularly significant impact on S&T leading enterprises；Enhancing the participation willingness of S&T leading enterprises can influence the enthusiasm of member units to some extent，while conversely，increasing the participation willingness of member units has a minimal effect on the strategic choices of the government and S&T leading enterprises；（2） Compared with the incentive mechanism，a reasonable punishment mechanism can more effectively promote the continued participation and enthusiasm of each member of the innovation consortium in key core technology research；（3） The income from the transformation of S&T achievements significantly impacts the enthusiasm of the innovation consortium members to continue participating in key core technology research，with a particularly pronounced effect on S&T leading enterprises；（4） When all the subjects of the innovation consortium adopt a positive strategy，the willingness of S&T leading enterprises to participate increases with the increase of the success probability of the key core technology breakthroughs. However，if only one party is actively innovating，the other party are unlikely to choose active innovation，and the government will not choose a strategy that is highly involved in support. Finally，this paper proposed the following countermeasures and suggestions： strengthening a well-functioning government，improving an efficient market，cultivating powerful subjects，and building a tolerant society within an integrated four-in-one collaborative system. These measures will empower the innovation consortium led by S&T leading enterprises，stimulate the innovation vitality of multiple subjects，achieve continuous breakthroughs in key core technologies，and cultivate new quality productive forces and new kinetic energy.

New digital empowerment ventures and their digital innovation activities are crucial for the integration of digital and physical realms and the development of new quality productive forces. However，due to the disadvantages of start-ups and the complexity of the digital innovation process，the outcomes of digital innovation in new digital empowerment ventures are often highly uncertain. Lean startup，as a crucial strategic approach to managing uncertainty，plays a significant role in optimizing the structure of new digital-enabled ventures and improving digital innovation performance. Based on the "strategy-structure-performance" paradigm，this study constructed a relational model between lean startup，modular architecture （including modular product architecture and modular organizational architecture），and digital innovation performance of new digital empowerment ventures. By conducting the hierarchical regression and bootstrap analysis of the data collected from 267 new digital empowerment ventures，the study found the following results： （1） Lean startup has a strong positive effect on the digital innovation performance of new digital empowerment ventures；（2） Modular product architecture and modular organizational architecture respectively play a mediating role in the relationship between lean startup and digital innovation performance of new digital empowerment ventures；and （3） Modular product architecture and modular organizational architecture act as a chain mediator between lean startup and digital innovation performance of new digital empowerment ventures. This study has clarified the mechanism by which lean startup influences the digital innovation performance of new digital empowerment ventures，thereby extending the research on lean startup and digital innovation. Additionally，it will provide theoretical basis and decision-making reference for the integration of digital economy and physical economy in China.

The entry of technology enterprises serves as the innovation engine for achieving high-quality economic development. Utilizing a dataset that matches the registration information of industrial and commercial enterprises with 283 prefecture-level cities from 2004 to 2018，this paper adopted the establishment of the Yangtze River Delta Urban Economic Coordination Committee as a quasi-natural experiment，and used the machine learning method to identify the impact of unified market construction on the entry of technology enterprises. The results showed that the construction of a unified market significantly stimulates the increase in the number of technology enterprises and the enhancement of their scale，and the above promotion effect is particularly pronounced in samples characterized by smaller city size，higher financial constraints and weaker government innovation support. The mechanism analysis revealed that the construction of a unified market facilitates the entry of technology enterprises through the effects of talent agglomeration，technology agglomeration，and venture capital agglomeration. Further research uncovered that，in comparison with core cities，the construction of a unified market has a stronger effect on the number and scale of technology enterprises entering peripheral cities，thereby contributing to regional balanced development. The above findings have not only provided a novel perspective for understanding the economic effects of unified national market construction，but also provided insights for the in-depth promotion of unified national market construction and the formulation of policies aimed at regional balanced development.

Open-source projects，particularly those in the domain of artificial intelligence，have become vital carriers for firms to achieve digital technological breakthroughs. Yet，how to choose an appropriate license that can ensure the sustainable development of open-source projects remains an unsettled question. Based on a sample of 2，536，526 open-source projects from GitHub，this study constructed a theoretical model of the differential impacts of open-source license on the sustainability of open-source projects in the context of technological complexity and empirically tested it by using the negative binomial regression method. The results showed that： （1） the adoption of open-source license has a significant positive effect on the sustainable development of open-source projects，manifested as increases in user interest and development activeness；（2） compared to restrictive license，permissive license can promote the sustainable development of open-source projects to a larger extent；（3） the license with patent grant clause has a stronger promoting effect on the sustainable development of projects than that without such a clause；and （4） technological complexity positively moderates the relationship between open-source license and the sustainability of open-source projects. This study has revealed the boundary conditions under which open-source license affects the sustainable development of open-source projects，thus helping firms improve governance mechanisms of open-source projects oriented towards complex digital technologies and offering insights for building a sustainable and prosperous open-source ecosystem.
