Based on the panel data of 29 provinces(autonomous regions and municipalities)in China from 1998 to 2020,this paper examines the relationship between environmental regulation and energy ecological footprint by using the intermediary effect model and taking green technology innovation as the intermediary variable.The results show that environmental regulation has an inverted U-shaped impact on energy ecological footprint and a U-shaped impact on green technology innovation.Green technology innovation can reduce energy ecological footprint and has a negative mediating effect between environmental regulation and energy ecological footprint.The influence of environmental regulation on energy ecological footprint in eastern,central,western,and northeastern regions is inverted U-shaped,but the effect is heterogeneous:the eastern region is larger than the central,western,and northeastern regions;green technology innovation in western China has the most significant effect on reducing energy ecological footprint.As an intermediary variable,green technology innovation effectively transmits the impact of environmental regulations on energy ecological footprint in the eastern,western,and central regions.
In order to explore the fertility desires and sensitivity to fertility policies of different population,this study takes residents aged 18-50 in Jiangsu Province as the survey subjects,and collects the basic information,fertility situation,personal fertility desire,attitudes towards fertility policies,etc.through questionnaires.Multiple ordered logistic regression and cluster analysis based on principal components are used for the study.The main results of logistic regression show that the older group and the group with more children have the higher support for policies such as"double reduction"and custody services;people who work longer hours prefer to have custody services and extend male maternity leave;the group with longer working hours,larger number of children born or larger ideal number of children would prefer to reduce excessive overtime.The clustering results indicate that in order to increase the fertility rate,targeted economic subsidies,public rental housing and other policies can be implemented for low education and low income groups;for the group with long working hours,excessive overtime can be reduced,custody services can be provided,and a social environment for grandparents to take care of children can be created.The research conclusions have reference significance for formulating and implementing fertility promotion policies and promoting long-term healthy development of the population.
Based on the data of the Chinese Longitudinal Healthy Longevity Survey(CLHLS),this article analyzes the relation between home care and mortality hazard among older adults with disability using Kaplan-Meier method and Cox regression to provide research evidence for developing home care service in China.Results show that 70.47%of objects die with average survival time of 2.45 years.Home care is characterized by children or spousal care,slight disability,paid care and care needs scarcely met.Slight disability,paid care and needs met have negative effects on mortality hazard of disabled elderly.Suggestions are put forward that needs should be met,vulnerable older adults with disability should be concerned,care skills should be trained,disability prevention should be undertaken in advance and long-term care insurance should be pushed to promote the health and wellbeing of older adults with disability.
Based on the perspective of total factor productivity,this paper empirically tests the impact of high-quality development of private real economy on common prosperity by using the panel data of 31 provinces in 2011-2021.Research has found that high-quality development of the private real economy has a significant promoting effect on common prosperity,and this conclusion still holds after replacing the model,introducing instrumental variables,and a series of robustness tests.The high-quality development of the private real economy can effectively enhance the level of innovation,increase tax revenue,and improve green production efficiency,and improving innovation level and improving green production efficiency play a partial mediating role in promoting common prosperity through high-quality development of the private real economy,while increasing tax revenue has no significant mediating effect.Further analysis indicates that government intervention and private real economy agglomeration play a positive regulatory role in high-quality development of the private real economy promoting common prosperity.Based on the above conclusions,this article proposes policy recommendations for the high-quality development of the private real economy and its sustained empowerment of common prosperity.
