Waste pollution is becoming a major health issue in many developing nations. Waste-reduction options have been investigated and proposed, but environmental culture-based initiatives have not. This study explores and advances Vietnamese families’ environmental culture related to waste management, using the Culture Tower framework and a contingent valuation method coupled with a Bayesian model (CVBM). Specifically, descriptive statistics measure environmental literacy, while CVBM determines household willingness-to-pay (WTP) and estimates WTP for waste treatment services (WTP4WTS). Based on our survey of 487 households across 11 communes and wards in Hai Phong City, local waste pollution has decreased over time, although the respondents remain concerned. Over 13% of households were dissatisfied with waste treatment services (WTSs), while approximately 50% were neutral. Most respondents (79.26%) were willing to pay for improved WTSs, with an average WTP of 60,200 VND (US$2.32) per household per month. Behavioral and perceptual factors, such as the desire for improved waste services, current perceived waste pollution, and the perception that pollution has worsened, were found to significantly influence this willingness. Our study makes three major contributions. First, it develops a novel CVBM framework that links environmental culture and an economic valuation method, strengthening green economy micro-behavioral research. Second, it advances the circular economy literature by highlighting household engagement and willingness-to-pay as key drivers of sustainable waste financing and resource-loop closure. Third, it provides empirical evidence to inform and refine Vietnam’s revised Law on Environmental Protection (2020), particularly in implementing the “polluter pays” principle, promoting waste classification at the source, and designing socially acceptable environmental financing mechanisms.

Du lịch giữ vai trò quan trọng trong sự phát triển kinh tế xã hội ở mọi cấp độ, từ toàn cầu đến quốc gia, địa phương. Tuy nhiên, du lịch phát triển ẩn chứa nhiều mối đe dọa đến môi trường sống, chất lượng nước, đời sống, văn hóa,... Do đó, cần xây dựng định hướng phát triển du lịch bền vững và xác định nhân tố nào có ảnh hưởng đến sự phát triển du lịch bền vững. Nghiên cứu này với mục đích xây dựng được mô hình nghiên cứu và xác định được các nhân tố ảnh hưởng đến phát triển du lịch bền vững tại Nghệ An, phân tích mức độ ảnh hưởng của các nhân tố đến phát triển du lịch bền vững tại Nghệ An. Bằng phương pháp phân tích hồi quy đa biến từ dữ liệu khảo sát 191 du khách và cán bộ quản lý tại Nghệ An, kết quả nghiên cứu cho thấy có 5 nhân tố ảnh hưởng đến phát triển du lịch bền vững tại Nghệ An được sắp xếp theo thứ tự gồm: Cơ sở vật chất, hạ tầng; Chất lượng dịch vụ du lịch; Sự tham gia của cộng đồng; Nguồn nhân lực du lịch; Tài nguyên du lịch. Bài báo là cơ sở góp phần giúp các nhà quản lý địa phương tìm và đưa ra các giải pháp phát triển du lịch bền vững tại Nghệ An trong thời gian tới.

Purpose: The purpose of this article is to analyze the cultural factors within a business that impact the organizational commitment of employees at Tasco Corporation, thereby proposing solutions to enhance their commitment to the company. Design/methodology/approach: Secondary data was collected from relevant materials on key themes: factors of corporate cultural influencing organizational commitment. A questionnaire were used for gathering primary information from employees at Tasco Corporation. The survey was conducted from August 2023 to December 2023. The questionnaire was designed based on the previous research findings, surveying 290 samples to identify the factors and levels of influence of corporate culture on employee organizational commitment at Tasco Corporation. Findings: There were five factors influencing employees’ organizational commitment at Tasco Corporation: Organizational communication, Training and development, Compensation and recognition, Empowerment, Risk-taking and innovation acceptance. Research, Practical & Social implications: Our findings could be used as a valuable reference for businesses to increase employee commitment to the organization. Originality/value: There have been numerous studies on the influence of corporate culture on employees’ organizational commitment. However, there was not any research has been conducted at Tasco Corporation. Therefore, we decided to undertake the topic of the article: "The Impact of Corporate Cultural Factors on Organizational Commitment at Tasco Corporation."

This paper introduces a novel four-party evolutionary game model to analyze cooperation dynamics in High-Value Mixed Cropping (HMC) systems integrating non-pesticide cacao, cashew nut, and free-range chicken farming within circular and sharing economy frameworks. The model uniquely examines strategic interactions among local government and three farming family types (cacao, cashew, and chicken), incorporating both regulatory mechanisms and cooperative behaviors. Through rigorous stability analysis and MATLAB simulations based on empirical data from Southeast Vietnam, we identify precise conditions for Evolutionarily Stable Strategies (ESSs) that sustain long-term cooperation. Our results demonstrate that government incentives (subsidies, technical support) and reputational sanctions critically shape farmers’ and consumers’ payoffs, thereby steering the system toward collective action equilibria. In particular, increasing the strength of positive incentives or reputational benefits enlarges the basin of attraction for full-cooperation ESSs, regardless of initial strategy distributions. Conversely, overly punitive sanctions can destabilize collaborative outcomes. These findings underscore the pivotal role of well-balanced policy instruments in fostering resilience, innovation, and resource circulation within rural agroecosystems. Finally, we propose targeted policy recommendations, such as graduated subsidy schemes, participatory monitoring platforms, and cooperative branding initiatives, to reinforce circular economy practices and accelerate progress toward the United Nations Sustainable Development Goals.

Waste pollution represents an increasingly serious problem affecting the health and well-being of people living in many developing countries. Many studies have examined and recommended waste-reducing solutions, yet environmental culture-based measures remain understudied. This study employs a novel approach that integrates the Culture Tower with the Contingent Valuation Method and a Bayesian model (CVBM) to explore and advance households’ environmental culture associated with waste management. Specifically, descriptive statistics capture respondents’ environmental perceptions and literacy, while the Bayesian model and CVM identify the determinants of households’ willingness to pay (WTP) and estimate WTP for waste treatment service (WTP4WTS), respectively. We found that despite the observed reduction in local waste pollution over time, respondents maintain a persistent concern regarding this issue. Over 13% of the households surveyed expressed dissatisfaction with waste treatment services (WTS), contrasting with nearly 50% of households that reported a neutral perspective. We also found that a significant majority (79.26%) of respondents were willing to pay for WTS, with an average WTP of 60,200 VND (US$2.32) per month. Importantly, the primary predictors of WTP4WTS were found to be the desire for improved waste services, current perceived waste pollution, and the belief that pollution has worsened over time. This study makes three key contributions. First, it develops an integrated CVBM framework linking environmental culture with economic valuation, thereby strengthening the micro-behavioral foundations of green economy research. Second, it advances the circular economy literature by identifying household engagement and willingness to pay as critical drivers of sustainable waste-financing and resource-loop closure. Third, it provides empirical evidence to inform and refine the implementation of Vietnam’s revised Law on Environmental Protection (2020), particularly in operationalizing the “polluter pays” principle, promoting waste classification at source, and designing socially acceptable environmental financing mechanisms.
