    Abstract The advancement of green technology innovation (GTI) is crucial for facilitating green development. China, the largest carbon-emitting economy, should prioritize the acceleration of GTI to augment global green economic growth and reduce carbon emissions. Green finance policy (GFP) is a common instrument for encouraging enterprises to develop GTI. This study, therefore, takes the pilot policy of China’s Green Finance Reform and Innovation Pilot Zone as a “quasi-natural experiment” and uses the difference-in-differences method to explore the impact and mechanism of GFP on Chinese enterprises’ GTI. Based on the empirical analysis using microdata from Chinese industrial enterprises from 2015 to 2021, the following conclusions can be drawn. First, GFP has a green innovation polarization effect. It facilitates the development of GTI in green enterprises while hindering the progress of GTI in polluting enterprises. Second, GFP enhances the GTI of green enterprises by promoting innovative behaviors and factor allocation optimization behaviors. However, GFP reduces the GTI of pollution enterprises by promoting non-innovative investments and reducing the efficiency of factor allocation optimization. Third, the combination of policies utilizing GFP, environmental subsidy, and R&D subsidy can effectively increase the GTI of polluting enterprises without compromising the GTI of green enterprises. This study offers empirical evidence and policy recommendations for establishing a green finance system in developing countries.

    Abstract Climate change affects public health, and improving eco-efficiency means reducing the various pollutants that are the result of economic activities. This study provided empirical evidence of the quantitative impact analysis of climate change on the health conditions of residents across China due to improvements that have been made to eco-efficiency. First, the indicators that were collected present adequate graphical trends and regional differences with a priori evidence about their relationships to each other; second, the present study applied Sensitivity Evaluation with Support Vector Machines (SE-SVM) to Chinese provincial panel data, taking the Visits to Hospitals, Outpatients with Emergency Treatment, and Number of Inpatients as proxy variables for the health conditions of the residents in each area and temperature, humidity, precipitation, and sunshine as the climate change variables, simultaneously incorporating the calculated eco-efficiency with six controlling indicators; third, we compared in-sample forecasting to acquire the optimal model in order to conduct elasticity analysis. The results showed that (1) temperature, humidity, precipitation, and sunshine performed well in forecasting the health conditions of the residents and that climate change was a good forecaster for resident health conditions; (2) from the national perspective, climate change had a positive relationship with Visits to Hospitals and Outpatients with Emergency Treatment but a negative relationship with the Number of Inpatients; (3) An increase in regional eco-efficiency of 1% increase the need for Visits to Hospitals and Outpatients with Emergency Treatment by 0.2242% and 0.2688%, respectively, but decreased the Number of Inpatients by 0.6272%; (4) increasing the regional eco-efficiency did not show any positive effects for any individual region because a variety of local activities, resource endowment, and the level of medical technology available in each region played different roles. The main findings of the present study are ...

    Abstract Whether the increasing regional eco-efficiency improves local residents’ health conditions has aroused great interest from scholars, practitioners or decision makers by implanting sustainable development strategy. And there lack direct quantitative evidence to testify the above influence is positive or negative, and computing its magnitude. Considering their uncertain, fuzzy and multi-factor complex relationship, the paper selected 5 indicators-Visits to hospitals, Outpatients with Emergency Treatment, Number of Inpatients, Number of Health Examinations, Patients Discharged-as proxy variables for residents’ health conditions and adopted regional eco-efficiency with other 6 control variables as explanatory variables, then built a Sensitivity Measurement Method with Support Vector Machines (SMM-SVM) to make analysis, finally applied Chinese province-level data from 2002 to 2016 to the proposed method. Empirical results shown that the changes at the national level and the provincial level were slightly different, which could be explained by control variables that characterize regional endowments: (1) From the national level, improving the eco-efficiency by 1% caused the decreasing of the number of Visits to Hospitals (0.041%), Outpatients with Emergency Treatment (0.029%), Outpatients with Emergency Treatment (0.307%) and a total 0.053%, equal to Patients Discharged (0.371%) minus Number of Inpatients (0.318%); (2) From the provincial level, 73.33%, 73.33%, 70.00% and 60.00%, 60.33% of 30 regions promoted the residents’ health condition by improving eco-efficiency, which was similar to the national level; (3) GDP per capita, Urbanization level, Population density, Medical personnel, Licensed (assistant) doctors, and Number of health care institutions were helpful to understand heterogeneity of degree of change. Provincial real situation and differences help to evaluate the effect of regional eco-efficiency on residents’ health conditions, and quantitatively guide the sustainable development and enhance public ...

    Abstract Objective. To investigate the effect of Xuan Bi Tong Yu Fang (XBTYF) on angiogenesis via the vascular endothelial growth factor- (VEGF-) Notch1/delta-like 4 (Dll4) pathway. Materials and Methods. Sixty Sprague-Dawley rats were randomly divided into six groups: control, sham-operated, myocardial ischemia model, and XBTYF treatment at 3.2, 1.6, and 0.8 g/kg. Electrocardiography was performed to evaluate the successful establishment of the model. Hematoxylin-eosin staining and transmission electron microscopy were carried out to observe the morphology and mitochondrial structure in myocardial cells, respectively. TUNEL staining was performed to assess the degree of cell apoptosis. The expression of VEGF-A, Notch1, Dll4, Bcl2, Bax, caspase 3, caspase 9, and cytochrome-c (Cyt-c) was observed by western blot. Results. XBTYF inhibited changes to the morphology and mitochondrial structure in cardiomyocyte and reduced cell apoptosis. Compared with the model group, XBTYF at all doses (3.2, 1.6, and 0.8 g/kg) reduced the expression of Notch1, Dll4, Bax, caspase 3, caspase 9, and Cyt-c, whereas expression of VEGF-A and Bcl2 was increased. Conclusion. XBTYF attenuated mitochondrial damage and cell apoptosis while promoting the angiogenesis of cardiomyocyte. The associated mechanism may be related to the VEGF-Notch1/Dll4 pathway.
