        中国政府采购活动空间网络结构特征研究——以京津冀地区为例

        牛美英,蒋皓杰 중한연구학회 2023 중한연구학간 Vol.0 No.31

        Interconnections between cities based on various “flows” are promoting the formation of city networks within regions. This paper focuses on the formation of a government procurement city network based on government procurement activities. Using government procurement data from the Beijing-Tianjin-Hebei region in 2021, this study measures the spatial network structure characteristics of the region from the perspective of government procurement. Based on data such as the scale of government procurement in the Beijing-Tianjin-Hebei region, a spatial network of government procurement activities is constructed to explore the connectivity pattern, network organization, and centrality characteristics of this network. The research indicates that a preliminary network pattern has been formed in the Beijing-Tianjin-Hebei region, and cities have established varying degrees of hierarchical network connections through government procurement activities. Beijing’s government procurement shows strong competitiveness and centrality characteristics. Tianjin, as one of the dual centers in the region, has relatively weaker external radiation function. The inter-provincial connectivity strength in Hebei Province is relatively weak. Finally, suggestions for the development and improvement of government procurement in the Beijing-Tianjin- Hebei region are proposed at the level of government procurement activities. These suggestions include promoting the development of a dual-center spatial structure in the Beijing-Tianjin-Hebei region, focusing on regional sub-centers, enhancing competitiveness in government procurement, and vigorously promoting the growth pole in the southern part of the Beijing-Tianjin-Hebei region.

        关于后疫情时代高中生家长线上教育选择的行为研究

        姜帅,龚驰,蒋皓杰 중한연구학회 2023 중한연구학간 Vol.0 No.32

        This paper aims to explore the willingness and attitudes of high school parents in the post-pandemic era when choosing online education (also known as online courses) for their students’ extracurricular studies. Based on the Integrated Technology Acceptance Model and taking into account the current market conditions, this paper constructs a factor model that influences the choices of high school parents in selecting online education. The model considers four dimensions: perception of online education quality, perception of software and hardware usage difficulty, perception of environmental influence, and perception of risk. A survey using questionnaires was conducted with 410 parents of high school students, and data analysis and hypothesis testing were performed using SPSS 27.0 and AMOS 29.0 software. The research findings indicate that performance expectation, effort expectation, and social influence have a positive impact on the willingness to choose online education, while perceived risk has a negative impact. The results demonstrate that even after the pandemic, high school parents continue to exhibit a strong willingness to choose online education. The conclusions of this paper provide insights into the psychological motivations and decision-making processes of high school parents when selecting online education. This offers theoretical support for relevant schools and businesses, helping them better understand the needs and behavioral patterns of parents and enabling them to formulate targeted strategies.
