Having observed increasing dangers to the environment posed by rising economic growth, they are seeking pathways to enable policy action on economic growth and environmental sustainability. Given the facts in theoretical and empirical studies, this study assessed the validity of the decoupling hypothesis by investigating asymmetricity in the relationship between environmental sustainability and economic growth in nine Eastern European countries from 1998 to 2017 using the cross-section augmented Dickey-Fuller(CADF) unit root, panel corrected standard error(PCSE), common correlated effect mean group(CCEMG), and Dumitrescu Hurlin causality approaches. Both population growth and drinking water are used as controlled variables. The outcomes establish strong cointegration among all the variables of interest. According to the results of CCEMG test, economic growth exerts short-term environmental degradation but has long-term environmental benefits in Eastern Europe;and population growth and drinking water exert a positive effect on environmental sustainability in both the short-and long-run. The results of Dumitrescu Hurlin causality test indicate that environmental sustainability is unidirectionally affected by economic growth. Based on these outcomes, we suggest the following policies:(1) the EU and OECD should implement member-targeted policies on economic growth and fossil-fuel use towards regulating industrial pollution, water use, and population control;and(2) the EU and OECD member countries should invest in environmental technologies through green research and development(R&D) to transform their dirty industrial processes and ensure productive energy use.展开更多

In that, the government was able to formulate policies that feature the positive interaction and coordinated development of regional medical investment, health and economy. Methods on index system for the evaluation of health investment, resident health and economic growth were constructed, and the coupling and coordination degree of the three systems were empirically studied based on the entropy weight method, the coupling coordination model and the gray correlation method. From the perspective of time series, the overall coupling and coordination level of Sichuan Province is relatively low, and the comprehensive development level of health investment and economic growth system has lagged behind the resident health system;from the perspective of spatial distribution characteristics, in 2019, the coordinated development level of health investment resident health and economic growth coupling in western Sichuan, southern Sichuan, northern Sichuan, eastern Sichuan and northern Sichuan is in the primary coordination stage, but there is a lag in the development of the health investment system between western Sichuan and southern Sichuan, and there is a lag in the development of the economic growth system between northern Sichuan and eastern Sichuan. From the analysis of gray correlation degree, the main correlation factors are diverse. All in all, the overall coordination level of health investment, resident health and economic growth in Sichuan Province is relatively low, and in order to achieve its coordinated development, it is necessary to narrow regional differences, formulate coordinated development strategies according to local conditions, and improve the overall coordination level.展开更多

This study aims to evaluate the relationship between CO<sub>2</sub> emissions and economic growth, industrial production, and foreign direct investment (FDI) in Vietnam. The ARDL estimation was used to process the dataset from World Bank. Results showed that economic growth, industrial production, and FDI have an impact on CO<sub>2</sub> emissions in the long run in Vietnam. Granger Causality test also indicated that there is a causal relationship between economic growth, industrial production, and CO<sub>2</sub> emissions in Vietnam from 1990 to 2018, at 5% statistical significance level. Proposed solutions to reduce CO<sub>2</sub> emissions but still promote economic growth toward the green growth orientation and zero carbon target attainment are as follows: 1) reduce the use of fossil energy in industrial manufacturing and replace it by renewable energy sources;2) use modern technology for all production sectors in economy;and 3) develop a legal framework for FDI projects selection and choose foreign investors with modern and low carbon emission technology.展开更多

Amidst Bangladesh’s economic growth, the challenges of rising inflation and increased living costs have become pressing concerns. Employing a mixed-methods approach combines quantitative data from a structured survey with qualitative insights from in-depth interviews and focused group discussions to analyze the repercussions of price hikes. Stratified random sampling ensures representation across affluent, middle-class, and economically disadvantaged groups. Utilizing data [1] from 2020 to November 2023 on the yearly change in retail prices of essential commodities, analysis reveals significant demographic shifts, occupational changes, and altered asset ownership patterns among households. The vulnerable population, including daily wage laborers and low-income individuals, is disproportionately affected by adjustments in consumption, income generation, and living arrangements. Statistical analyses, including One-Way ANOVA and Paired Sample t-tests, illuminate significant mean differences in strategies employed during price hikes. Despite challenges, the prioritization of education remains evident, emphasizing its resilience in the face of economic hardships. The result shows that price hikes, especially in essential items, lead to substantial adjustments in living costs, with items like onions, garlic, and ginger experiencing significant increases of 275%, 108%, and 483%, respectively.展开更多

In this paper,based on the data during 1994-2016,error correction model is established to test and analyze the relationship between economic growth and export of agricultural products in China. The results show that change of agricultural products export in China has positive impact on GDP in short time,and they also have longterm stable relationship. When they lag for different periods,economic growth and export of agricultural products have unidirectional causality.展开更多

文摘A detailed investigation of the nexus between economic growth and energy use is imperative for formulating sustainable development policies.In this study,we examine panel cointegration and causality relations among economic growth,energy use,capital stock,and labor in 30 Chinese provinces between 2000-2019.We conduct a comprehensive empirical analysis based on panel modeling and a neoclassical production function.The findings of the second-generation panel unit root and co-integration tests reveal that these variables have long term co-integration linkages.We then perform a panel cointegration estimation using the fully modified ordinary least squares technique and find that total energy consumption,electricity consumption,capital stock,and labor significantly influence economic growth at the national and regional levels in China.Moreover,the outcomes of the Dumitrescu-Hurlin causality test indicate the existence of a two-way causal nexus between economic output and total energy consumption at the national level,but only a causal link from GDP to total energy use in the eastern and central regions.Conversely,a causality from total energy use to economic output is identified in the western region.Finally,we provide policy implications for the sustainable development of both energy and the economy at the national and regional levels.

文摘[Objectives]This study was conducted to study the effects of whole-plant corn silage and whole-plant wheat silage on growth performance and economic benefits of beef cattle.[Methods]Thirty Simmental crossbred cattle were selected and randomly divided based on their weight into two groups,15 cows in each group,with an average weight of 398 kg.Each group was fed the same concentrated feed,and the whole-plant corn silage and wheat silage were fed as roughage feed,respectively.The experimental period was 90 d.[Results](1)There was no significant difference in the initial weight of beef cattle between test group 1 and test group 2(P>0.05).Compared with group 2,group 1 had a higher final weight,average daily gain,and dry matter intake of beef cattle,without significant differences(P>0.05).Group 1 was 0.58%,1.99%,and 1.43%higher than group 2,respectively.The feed-to-gain ratio of test group 1 decreased by 0.54%compared with test group 2(P>0.05),with no significant difference therebetween.(2)The economic benefit of group 1 was 11.45 yuan/(day·capita),while the economic benefit of group 2 was 2.41 yuan/(day·capita),and group 1 was 9.04 yuan/(day·capita)higher than group 2.[Conclusions]Whole-plant corn silage for feeding beef cattle has the advantages of good weight gain and low breeding cost,and can be popularized in beef cattle fattening.
文摘We should calculate the coupling degree of medical investment, resident health and economic growth in Sichuan Province, and make clear the coordinated development of the aforementioned three factors. In that, the government was able to formulate policies that feature the positive interaction and coordinated development of regional medical investment, health and economy. Methods on index system for the evaluation of health investment, resident health and economic growth were constructed, and the coupling and coordination degree of the three systems were empirically studied based on the entropy weight method, the coupling coordination model and the gray correlation method. From the perspective of time series, the overall coupling and coordination level of Sichuan Province is relatively low, and the comprehensive development level of health investment and economic growth system has lagged behind the resident health system;from the perspective of spatial distribution characteristics, in 2019, the coordinated development level of health investment resident health and economic growth coupling in western Sichuan, southern Sichuan, northern Sichuan, eastern Sichuan and northern Sichuan is in the primary coordination stage, but there is a lag in the development of the health investment system between western Sichuan and southern Sichuan, and there is a lag in the development of the economic growth system between northern Sichuan and eastern Sichuan. From the analysis of gray correlation degree, the main correlation factors are diverse. All in all, the overall coordination level of health investment, resident health and economic growth in Sichuan Province is relatively low, and in order to achieve its coordinated development, it is necessary to narrow regional differences, formulate coordinated development strategies according to local conditions, and improve the overall coordination level.
文摘Vietnam’s economy has been developing strongly in recent years;however, it is necessary to examine the impact of its economic activities on environmental quality. This study aims to evaluate the relationship between CO<sub>2</sub> emissions and economic growth, industrial production, and foreign direct investment (FDI) in Vietnam. The ARDL estimation was used to process the dataset from World Bank. Results showed that economic growth, industrial production, and FDI have an impact on CO<sub>2</sub> emissions in the long run in Vietnam. Granger Causality test also indicated that there is a causal relationship between economic growth, industrial production, and CO<sub>2</sub> emissions in Vietnam from 1990 to 2018, at 5% statistical significance level. Proposed solutions to reduce CO<sub>2</sub> emissions but still promote economic growth toward the green growth orientation and zero carbon target attainment are as follows: 1) reduce the use of fossil energy in industrial manufacturing and replace it by renewable energy sources;2) use modern technology for all production sectors in economy;and 3) develop a legal framework for FDI projects selection and choose foreign investors with modern and low carbon emission technology.
文摘Ecotourism is one of the major drivers of economic growth and rural development in many countries involved in wildlife resource management.The objective was to assess the contribution of ecotourism to economic growth and rural development offered to people living in communities around Matusadonha National Park.A total of 140 participants were interviewed and questionnaires were administered to the same number of people.Data were analysed using both qualitative and quantitative methods.Results show that the majority of participants(57%)were females.Safari operations were the major(54.7%)ecotourism activity in Matusadonha National Park.Above half(58.8%)of participants indicated that ecotourism contributed toward economic growth in communities around Matusadonha National Park.Most people(343)were employed on a part-time basis from 2000 to 2022.Participants indicated that the standard of living in most communities increased by more than 50%.Above 50%of participants were satisfied with the contribution of ecotourism towards rural development.It can be concluded that ecotourism has the potential to improve economic growth and rural development if close monitoring and accountability of funds are monitored closely.Local people should be included in the accountability of funds and management of wildlife resources to improve economic benefits to local people.
文摘As an aspect of human capital,a positive association exists amongst health,productivity,and growth in output per capita.On the other hand,social infrastructure defined by the institution of governance has a direct effect on the environment upon which productive activities take place to determine outcomes.Nigeria like most African countries is bedevilled by the high prevalence of inadequate health financing and poor governance.Health financing for Nigeria consistently has fallen short of the AU health funding commitment of 15%of annual budgetary allocation to the health sector.Secondly,poor governance conditions available resources and shape the state of infrastructure,particularly health infrastructure and socioeconomic conditions.In turn,this determines individuals’level of exposure to health risks and their capacity to actively contribute to productive activity for growth stimulation and sustainability.Against this backdrop,this study added to the existing literature in the context of Nigeria,by theoretically applying the Solow augmented Mankiw-Romer-Weil structural model in the examination of the impact of government size and governance quality in the health sector,on economic growth.Autoregressive Distributed Lag(ARDL)model was adopted in the estimation.Findings show that governance quality adversely affects growth and this reduces the capacity of health spending to stimulate growth by an almost equal margin.As a result,this study recommends legislative backing to the AU health funding commitment in Nigeria.
文摘This study delves into the multifaceted impact of price hikes on the standard of living in Bangladesh, with a specific focus on distinct socioeconomic segments. Amidst Bangladesh’s economic growth, the challenges of rising inflation and increased living costs have become pressing concerns. Employing a mixed-methods approach combines quantitative data from a structured survey with qualitative insights from in-depth interviews and focused group discussions to analyze the repercussions of price hikes. Stratified random sampling ensures representation across affluent, middle-class, and economically disadvantaged groups. Utilizing data [1] from 2020 to November 2023 on the yearly change in retail prices of essential commodities, analysis reveals significant demographic shifts, occupational changes, and altered asset ownership patterns among households. The vulnerable population, including daily wage laborers and low-income individuals, is disproportionately affected by adjustments in consumption, income generation, and living arrangements. Statistical analyses, including One-Way ANOVA and Paired Sample t-tests, illuminate significant mean differences in strategies employed during price hikes. Despite challenges, the prioritization of education remains evident, emphasizing its resilience in the face of economic hardships. The result shows that price hikes, especially in essential items, lead to substantial adjustments in living costs, with items like onions, garlic, and ginger experiencing significant increases of 275%, 108%, and 483%, respectively.
文摘The proposal of"Belt and Road Initiative"has brought greater opportunities for the development of China's agricultural trade,but in recent years,China's agricultural trade deficit has shown a trend of gradually expanding.Based on the data of seven years from 2012 to 2018,this paper empirically analyzes the agricultural trade effect of China's economic growth.It is concluded that the consumption effect of agricultural trade in China's economic growth is anti-trade biased,the production effect and comprehensive effect of agricultural trade are pro-trade biased,and China's terms of trade of agricultural products tend to improve.This paper puts forward some relevant suggestions from the aspects of export structure,production mode,agricultural product processing,logistics mode,e-commerce system,inspection and quarantine and so on.
文摘After entering into WTO,export volume of agricultural products in China quickly increases,but its proportion in total trade volume becomes lower and lower,and there are more and more trade barriers of agricultural products. In this paper,based on the data during 1994-2016,error correction model is established to test and analyze the relationship between economic growth and export of agricultural products in China. The results show that change of agricultural products export in China has positive impact on GDP in short time,and they also have longterm stable relationship. When they lag for different periods,economic growth and export of agricultural products have unidirectional causality.
