摘要: In Gansu Province, China, Wuwei City is an ecologically fragile migration area at the intersection of the Loess Plateau, the Qinghai-Tibet Plateau, and the Mongolia-New Plateau. Using the Triangular Fuzzy TOPSIS method and the obstacle factor diagnostic model, the implementation performance and follow-up support issues of the Ecological Resettlement Project were analyzed from the perspective of the eco-migrant and the public value theory. In contrast to traditional performance appraisal methods, Triangular Fuzzy TOPSIS breaks through the ambiguity of complex environments and subjective information and effectively quantifies the fuzziness of evaluator language variables to improve the validity. The overall performance of the Ecological Resettlement Project in Wuwei is good; the average closeness degree of process is higher than outcome. Migrants rated the fairness of the project as the highest, followed by support, economic outcome, and satisfaction. Gulang County's performance in the Ecological Resettlement Project is the best, followed by Tianzhu County and Liangzhou District. Project obstacles were mostly related to the outcome dimension, especially the ecological restoration and management, the return to poverty risk, and industrial development on the resettlement site. The main obstacle to the process dimension is migrant satisfaction with government subsidies. Research results provide case study support and experience inspiration for migrant relocation models and their long-term livelihood improvement in the context of rural revitalization.2023-05-30T07:36:58ZTibetan Herders' Life Satisfaction and Determinants under the Pastureland Rehabilitation Program: A Case Study of Maduo County, ChinaXia, CuizhenZhou, LihuaWang, YaPei, Xiaodonghttp://ir.casisd.cn:80/handle/190111/120362023-05-30T07:36:44Z2023-05-30T07:36:44Z题名: Tibetan Herders' Life Satisfaction and Determinants under the Pastureland Rehabilitation Program: A Case Study of Maduo County, China

摘要: The Pastureland Rehabilitation Program (PRP) has been implemented for nearly 20 years, and the lives of herders in different regions have been affected to varying degrees. The level of people's well-being could measure the success of policy. Taking Maduo County as an example, the life satisfaction of 266 Tibetan herders was investigated through a participatory questionnaire survey in July 2021. Multiple linear regression and optimal scale regression were constructed to analyze the impact of the satisfaction of different aspects of life and PRP on life satisfaction, respectively. The results show that the herders in Maduo County had relative high satisfaction in various aspects of life and overall life, and leisure and consumption were important aspects influencing life satisfaction. The relative living standard, the difficulty in borrowing and the quality of government services had a significant positive impact on herders' life satisfaction. Occupation and migration location also led to the significant differences of life satisfaction. However, the income changes caused by PRP and subsidy levels did not show a significant impact. We discussed the particularity of Maduo County and suggested that more attention should be paid to the improvement of the social environment such as wealth disparity, channels of assistance, working environment, and the effective assistance formulated according to the demands of different groups needs to be optimized continuously, so as to enhance the self-development ability of herders.2023-05-30T07:36:44ZAssessment of Cities' Adaptation to Climate Change and Its Relationship with Urbanization in ChinaPei, XiaodongWu, JingXue, JunboZhao, JincaiLiu, ChangxinTian, Yuanhttp://ir.casisd.cn:80/handle/190111/120322023-05-30T07:36:39Z2023-05-30T07:36:39Z题名: Assessment of Cities' Adaptation to Climate Change and Its Relationship with Urbanization in China

摘要: Global climate change has led to more frequent occurrences of extreme, dangerous events; therefore, it is urgent to enhance cities' adaptation to climate change. Focusing on the impact of high temperature, low temperature, drought, and flooding, we established multi-dimensional assessment systems covering natural, economic, and social elements for cities' climate change adaptations. Based on the assessment systems, studies on adaptation to climate change were conducted in 248 cities in China using the entropy weight method, coefficient of variation method, and exploratory spatial data analysis; with the help of geographically weighted regression (GWR), the relationships between four types of urbanization and cities' adaptation to climate events were explored. The results showed the following: (1) High-administrative-level cities had higher adaptation than ordinary prefecture-level cities. (2) The differences in adaptation to the four types of climate events between cities within each of the seven regions in China presented significantly different spatial patterns. (3) Under the four types of climate events, the global spatial correlations of cities' adaptations in China were positive. The agglomeration characteristics of adaptation were mainly H-H and L-L agglomerations. (4) When analyzing the impacts of four types of urbanization on cities' adaptation to climate events, the fitting effects of GWR models were far better than those of OLS models. Population urbanization, economic urbanization, land urbanization, and industrial urbanization had different impacts on adaptation. Under the influence of social and economic development, the urbanization regression coefficients of different cities had significant spatial differences.2023-05-30T07:36:39ZThe Impact of Digital Technology on Land Rent-Out Behavior: Information Sharing or Exclusion?Zuo, XiaofanHong, Zhishenghttp://ir.casisd.cn:80/handle/190111/120222023-05-30T07:36:28Z2023-05-30T07:36:28Z题名: The Impact of Digital Technology on Land Rent-Out Behavior: Information Sharing or Exclusion?

摘要: In the digital age, it is critical to understand the nexus between digital technology (DT) and land rent-out behavior (LRB). It has implications for reducing the rate of land abandonment to achieve sustainable agricultural development. A large dataset (n = 5233) dating from 2016 and coming from the China Family Panel Studies (CFPS) is used to explore the impact of DT on LRB by applying several econometric models, also including the Recursive Bivariate Probit (RBP) model and Chain Multiple Mediation effect (CMM) model. We provide empirical evidence that the DT's information sharing effect positively impacted LRB, while an opposite effect is observed by the digital divide (DT_GAP) i.e., information exclusion that negatively impacted LRB. We further test the effect of two other variables, namely digital information dependence and non-farm jobs supposed as mediating factors of DT and DT_GAP in influencing LRB, respectively in a positive and negative way. In particular, the variable nonfarm jobs plays a mediating role conditional on the variable digital information dependence as a mediating variable at the first level. In addition, statistical tests reveal that the impact of DT and the DT_GAP on LRB is not significant in terms of regional preferences but is significant in terms of age of householder and household income level.2023-05-30T07:36:28ZThe Impact of Internet Use on Perception of the Poor-Rich Gap: Empirical Evidence from ChinaZuo, XiaofanHong, Zhishenghttp://ir.casisd.cn:80/handle/190111/120192023-05-30T07:36:24Z2023-05-30T07:36:24Z题名: The Impact of Internet Use on Perception of the Poor-Rich Gap: Empirical Evidence from China

摘要: The advancement of Internet technology has provided a great impetus to alleviate poverty and promote economic progress. However, studies on the negative impact that the development of the Internet may have on individual perceptions are still rare. This paper uses data from the China Family Panel Studies (CFPS) in 2018 to construct multiple econometric models to empirically study the impact of Internet use (ITU) on the perception of the poor-rich gap (PPRG) and its mechanism in China. The instrumental variable (IV) model and Heckman model are used to solve potential endogenous problems. The research found that ITU has aggravated the PPRG of residents, and the test results are still robust after considering various endogenous sources. Additional analysis shows that the degree of dependence on the Internet is one of the transmission mechanisms of ITU on the impact of the PPRG, and its mediating effect accounts for 32.12% of the total effect. Another test result of the impact mechanism shows that the Internet media expands the reference group of residents through virtual areas and aggravates the PPRG of residents. Some test results from the perspective of heterogeneity show that: the effect of urban residents' ITU on PPRG is higher than that of rural residents. ITU of residents in economically developed areas has a significantly higher effect on the PPRG than residents in economically underdeveloped areas. The impact on ITU by residents of different age groups on aggravating the PPRG show an obvious increasing linear law. Our research provides an ITU interpretation path for the impact of PPRG from sociological theory and provides a new entry point for the impact of the Internet and subjective well-being.2023-05-30T07:36:24Z中国城市气候变化适应性评价裴孝东吴静薛俊波赵金彩刘昌新田园http://ir.casisd.cn:80/handle/190111/119892023-05-30T07:35:53Z2023-05-30T07:35:53Z题名: 中国城市气候变化适应性评价
