With rapid changes and increasing uncertainty in the market environment, enterprise innovation ecosystems (EIEs) have increasingly been promoted in the past decade. Nevertheless, research on EIEs has fallen into a fuzzy state. Scholars have scattered views on the subject and have not systematically classified it, leading to a discussion regarding its conceptual rigor and comprehensive analysis. The purpose of this article is to conduct integrative research on EIEs and to examine all the relevant issues of existing views. This study screened all relevant topics in the past decade through the WOS database and identified significant journal articles. By reviewing and sorting out the relevant thematic literature from 2011 to 2020 and performing keyword cluster analysis, the research focus and hot spots of EIEs are determined. The entity structure, main types, dynamic mechanism, and evolution mechanism of EIEs were elaborated, and the definition of an EIE is finally determined. Through an analysis of the emerging viewpoints of EIEs, the hot spots of this topic are discussed. These streams provide opportunities for further research to consolidate the concepts of EIEs.

In this study, we investigate whether outbound foreign direct investment (OFDI) either augments or impedes domestic public and private investment, incorporating the role of institutional quality into the context of developed and emerging countries. To this end, we apply a cross-sectional-autoregressive-distributed lag (CS-ARDL) approach to analyze panel data from the period 1996–2017. Our empirical findings suggest that OFDI augments private capital formation for developed countries. Institutional quality (IQ) is found to be a driving factor that promotes private capital formation in the established economies of developed countries. However, OFDI has a negative association with the public capital formation in the established economies of developed countries, while IQ has a positive association with it. In the context of emerging economies, OFDI is found to be too insignificant to have an effect on private and public capital formation. Interestingly, IQ has a detrimental effect on both private and public capital formation in emerging economies. Our findings are robust. The empirical findings of this study imply that institutional quality should continue to be improved in developed countries, while it should surpass a certain threshold for emerging economies to promote domestic capital formation.

A comprehensive evaluation model that combines an analytical hierarchy process (AHP) method and the improved version of the Criteria Importance Through Inter-criteria Correlation (CRITIC) method is proposed to solve integrated assessment problems related to the service status of groins in waterways. In view of the influencing factors and functional characteristics of damaged groins for waterway regulation, a waterway groin service status (WGSS) evaluation index system with a hierarchical structure was constructed using target-criteria elements. Additionally, based on the multi-attribute characteristics of the indicators, standards for rating and assigning values to elemental indicators were developed. Considering that traditional empowerment methods are rather one-sided and limited, an AHP-improved CRITIC method combination assigning optimization model was established based on the least squares principle, and the optimal combination weights were solved by the Lagrange multiplier method. The reliability and applicability of the model were tested by successfully applying the evaluation model to the comprehensive evaluation of the service status of spur dikes in the upper reaches of the Yangtze River. The results showed that the combined weights that were calculated by the AHP and the improved CRITIC optimization model were able to reflect both subjective and objective information, which makes up for the shortcomings of a single assignment method, and the weights assigned to the service status evaluation indexes for groins were reasonable. The comprehensive evaluation method to determine the service status of groins proposed in this paper was more accurate than the traditional evaluation method with subjective assignment and provided a scientific basis for decision making to maintain the sustainability of groin function.

<div>Supply chain management is key to industry efficiency, while information security and transparency are at the core of operations management. Blockchain technology shows great potential in this regard and can effectively make up for existing shortcomings. This article deeply explores the application of blockchain in new energy vehicle supply chain management, focusing on enhancing the systematization and collaboration of the supply chain through smart contract mechanisms. We established a collaborative contract model for the three-level supply chain. Especially from the perspective of the intermediate supply chain, we designed a smart contract mechanism to optimize key links such as order processing, payment, and logistics tracking, and used the alliance chain to ensure the safe sharing and sharing of information. At the same time, we have also developed an interactive system for each link of the supply chain and achieved smooth interaction in the new energy vehicle supply chain by adjusting the parameters and functions of smart contracts. Using the Ethereum scripting language, we built a blockchain smart contract mechanism based on supply chain contracts. This research not only demonstrates the potential value of blockchain technology in promoting supply chain information sharing and enhancing mutual trust, but also highlights its importance in supply chain management innovation and practical application.</div>

Many scholars have conducted research on the traffic oscillations and reproduced the growth pattern by establishing stochastic models and simulations. However, the growth pattern of oscillations caused by uncertainty have not been thoroughly studied. Recently, a frequency domain stability analysis method was proposed to analyze the discrete stochastic model. This paper extends this analysis to a continuous situation based on frequency domain tools (e.g., Laplace transform) by introducing a continuous bandlimited white noise. The analytical expression for the evolution of speed standard deviation has been derived. Our study of a homogeneous case reveals an interesting phenomenon: when |G(ω)|∞<1, the speed variance will converge to a constant value, which only depends on the self-disturbance of vehicles. The simulation results verified that the continuous models and corresponding discrete model tend to be consistent when the discrete time step tends to the infinitesimal. Overall, this paper makes up for the deficiency of previous studies on continuous oscillations in car-following theory and can potentially be used to develop new control strategies to help dampen traffic oscillations.

Sustainable tourism is essential for tourism sector development. Environmentally responsible behaviors and behavioral intentions are important prerequisites for sustainable tourism. This research explores the behavioral intentions of university tourism students and significant factors affecting these behavioral intentions. The questionnaire survey method was applied to university students from the tourism departments of nine universities in Taiwan. A total of 390 valid questionnaires were collected. The pro-environmental behavioral intentions of the students ranged from moderate to high. Environmental knowledge positively affected behavioral intentions and positively influenced environmental sensitivity and environmental responsibility. Furthermore, environmental sensitivity and environmental responsibility exerted a full effect in mediating the relationship between environmental knowledge and behavioral intentions. Hence, increasing students’ environmental knowledge will enhance their behavioral intentions. However, by improving students’ sensitivity and responsibility, their intentions to protect the environment can be more effectively elevated. Development implications and recommendations for sustainable tourism and higher education are provided.

This paper takes Taoxichuan Cultural and Creative Street as a case study. It explores how enterprises activate the value of “industrial heritage” resources and achieve sustainable development from the perspective of affordance theory. Research findings indicated that: (1) the creation of a culturally recognized context performs a vital role in activating the industrial heritage; (2) the evocation of industrial heritage resources is a dynamic process from the realization of fundamental values to the actualization of high-level values; and (3) the evoked industrial heritage resources can achieve sustainable corporate development. Additionally, the research findings provide reference for enterprises to realize high-level values of industrial heritage resources by creating contexts to transform them into sources of innovation in the post-pandemic era.

Ecological and environmental protection is the core content of ecotourism development. A quantitative evaluation of the effects of ecotourism environmental protection (hereinafter referred to as EEP) measures on protected areas is conducive to a deeper understanding of the key issues related to ecotourism development in China, thus providing the theoretical basis for formulating the relevant national policies of sustainable ecotourism development in China. This paper first discusses the evaluation index system and then establishes an index evaluation model of EEP measures and their effects on protected areas. Using surveys of more than 1110 protected areas in 27 provinces (autonomous regions or municipalities), we evaluated the EEP measures and their effects from a quantitative and spatial perspective. The completeness of EEP measures for Chinese protected areas was moderately effective, and the implementation status of the protection measures varied with the protection region. The effectiveness of EEP measures in different provinces and regions showed significant differences. The effectiveness decreased from east to west. The evaluation index values of the environmental protection measures displayed a high correlation with the effects of environmental protection on protected areas. The ecological protection measures should be further improved and strengthened according to their regional differences during ecotourism development.
