The Impacts of Lower Population Growth on the Quality of Life and Economic Development：China＇s Experience

China is the most populous country in the world.The total Population on the mainland of China has in-creased from 540 million in 1949 to 1.18 billion by the end of 1993.China adopted a population policy by namc of"controlling population growth and im-proving the quality of the human resources',which has been deeply rooted in the hearts of the Chinese pcoplc.The overw helming majority of the Chinese people have recognized the necessity for implementing the family planning programme not only for the sustained devel-opment of the country,but also for the benefits of their own familie cs.

Research on the Impact of Innovation Drivers on the Quality of Economic Growth in China

The quality of economic growth is a prominent issue in the process of economic growth worldwide.This paper builds relevant econometric models and uses the provincial panel data from 2003 to 2015 to analyze the impact of innovation drivers on China’s economic growth.The empirical results show that technological innovation and institutional innovation have a significant role in promoting the quality of China’s economic growth,and the effect of institutional innovation is stronger than that of technological innovation.In terms of regions,the innovation driver has the greatest contribution to the quality of economic growth in the eastern region of China,with the western and central parts ranking second and third.However,the role of institutional innovation in the eastern region is prominent,and the role of technological innovation is weak.Only institutional innovation in the central region has a significant role in promoting the quality of economic growth.Only technological innovation in the western region has a positive effect on the quality of economic growth,and the impact is weak.The regional differences in the impact of innovation-driven economic growth are obvious.

Environmental Pollution and Economic Growth in China: A Test of the Environmental Kuznets Curve

We apply a two pronged approach to analyze the presence of Environmental Kuznets Curve, EKC, in three types of emissions in the People’s Republic of China from 1994 to 2014: a structural breakpoint analysis and a model based test. We apply it to PM2.5, industrial waste and domestic water pollution time series, and find evidence of EKC in all three types of emissions that require appropriate policy.

Relationship between the Environment and Economic Growth in China via Exports: A Perspective of Ecological Impact (2000-2014)

China’s swift and substantial economic growth over the past 20 years has made the country one of the top industrial powers in the world, second only the United States. From the perspective of ecology and the impact on the environment produced by economic and industrial growth, the exports that have driven rapid growth have also resulted in an alarming level of environmental pollution in major Chinese cities. Research has shown that the Chinese government’s investment in bringing down pollution levels has been insufficient and ineffective. The monetary amount allocated for pollution reduction has barely reached 0.15% of the country’s GDP and has failed to meaningfully reverse the effects of industrialization, including increased exports and economic growth rates affecting China’s ecology. The present study investigated China’s ecological situation in terms of the industrial production that has generated its level of exports, with special focus on problems related to water, air, and solid waste. An econometric analysis was conducted to determine the relationship between the main variables. The exports and GDP (dependent variable), air pollution, water pollution, and industrial solid waste (independent variables) were provided by the Institute of Statistics and the Environment Institute of China for this study. The data was managed in Econometric Eviews 7.0 software and yielded an adjusted R2 of 96.09% (high correlation) with an interesting correlation between the exports and three independent variables;after subsequent variable analysis, we found that investments in water and industrial solid waste were not significant (i.e., that said investments have failed to solve the pollution problem). It is necessary to review the Chinese investment policy with special attention to these variables to appropriately respond to China’s ecological crisis.

Effect of Biofertilizer on Growth, Productivity, Quality and Economics of Rainfed Organic Ginger （Zingiber officinale Rosc.） Bhaisey cv. in North-Eastern Region of India

Ginger yields in the NorthEastern region of India are low because the extremely poor farmers of the region can not afford to apply any chemical fertilizers and hence apply only the locally-available farmyard manures to ginger fields. Biofertilizers may be a cheap source of fertilizers for ginger cultivation as they can increase nutrient availability and improve rhizome quality and are required in small quantity. An investigation was thus undertaken to study the effect of different biofenilizers on growth, productivity, quality and economics of organic ginger grown under rainfed condition in NorthEastern region of India. Seed treatment with biofertilizers enhanced growth, increased rhizome yield by 19.0% and resulted in 32.4% higher net profit over control. Among the seed treatments, Azotobacter 5.0 kg ha＂l, Azospirillum 3.75 kg hal and Phosphotica 3.75 kg ha-1 were found optimum in improving most of the growth attributes, increasing yield components and yield of rhizome by 5.6%-13.5%. They also improved rhizome quality by increasing specific gravity, oleoresin and dry matter content and by decreasing crude fibre in rhizome. They resulted in higher net return by 4.0%-12.0% as compared to their other levels. Combined use of Azotobacter 5.0 kg hal along with Phosphotica 3.75 kg ha＂l was found to be the best treatment combination which greatly improved growth and yield attributes of ginger and ultimately recorded markedly higher productivity （2.0%-23.5%） over other combinations. This treatment combination improved the quality of the produce and resulted in the highest gross return （$4,905 hal）, net return （$3,525 hal） and return per dollar （3.55） invested in ginger cultivation. It appears that growing organic ginger by treating the seed rhizome with Azotobacter 5.0 kg ha-~ along with Phosphotica 3.75 kg ha-1 can result in good growth and high productivity of improved quality rhizome and ultimately result in maximum net profit and thus can be recommended for the NorthEastern region of India.

Double dividend of carbon intensity:environmental-quality improvement and sustainable economic growth

This paper established an equilibrium model including representative household,government,and eight industries,and two different environmental policy tools such as carbon intensity and carbon cap were added into the model.The paper points out that the carbon intensity policy imposed on major high-emission industries achieved double dividend of environmentalquality improvement and sustainable economic growth under the condition of proper constraint target.This result supports the environmental Porter hypothesis.This paper finds out that the double dividend is due to the fact that environmental governance policy leads to the rising price of resources and demand of labors,resulting in an effective redistribution of production factors among industries and sustainable economic growth.Furthermore,this paper estimates the marginal effect of economic structure on carbon emission and carbon intensity and provides targeted suggestions.

Measuring Quality of Economic Growth Incorporating Environment and Social Welfare:a Total Productivity Approach with an Application on China

By extending the traditional productivity theory,a new concept total productivity( TP) is introduced. Using a directional distance function approach,the concept is applied to measuring economic growth of 8 economic regions of China covering an 18 years period( 1997—2014) and test its convergence. Results showed that TP grew at an average rate of 6. 6% per year led mainly by technical change( 6. 5%). When environmental undesirable outputs are included,the Middle Yellow River,Northwest and Southwest regions of China witnessed higher productivity changes. Results of the convergence analysis revealed that China had made progress in reducing regional imbalance in growth. Inclusion of undesirable output showed that the energy-saving emission reduction policies had speed up the convergence rate of TP and environment oriented productivity. However,China's welfare oriented productivity is still very low.

Effects of Stocking Density on Water Quality,Growth and Economic Benefits of Chinese Softshelled Turtle Pelodiscus sinensis in Ponds

The Chinese soft-shelled turtle Pelodiscus sinensis is a high-valued freshwater species cultured in China.This study investigated the effects of stocking density on water quality,growth performance and economic return of Pelodiscus sinensis cultured in ponds.P.sinensis were stocked at densities of 1 ind./m^2(LD:low stocking density) and 2 ind./m^2(HD:high stocking density) in 3 000-m^2 ponds,with three replicate ponds for each density.P.sinensis juveniles were fed with a commercial dry pellet feed of 46% crude protein and minced fillet of silver carp ans cultured for 122 days.The results showed that the levels of total nitrogen(TN),total phosphorous(TP),Chlorophyll-a(Chl.a) and turbidity in LD treatment were significantly lower than those in HD treatment(P<0.05).The mean TN and TP concentration in LD treatment was 29.3% and 35.7% lower compared to the HD treatment at the end of the experiment,respectively.Mean survival rates,final weight,average growth rates and PER were significantly higher in LD treatment compared with the HD treatment(P<0.05),respectively.Production was significantly affected by stocking density,which was higher in HD treatment,but the net income was higher in LD treatment.The results suggest that turtles with mean weight 55.6 g rearing at a low stocking density(1 ind./m^2) in ponds had a positive effect on overall economic return and was effective at improving turtle growth performance and water quality.

The Impact of Foreign Direct Investment on Economic Growth: Nigeria Experience

This study investigated the impact of foreign direct investment on economic growth in Nigeria. Secondary source of data was employed in this study from 1986 to 2017 which were sourced from Central Bank of Nigeria Statistical Bulletin (2017) published in 2018 and World Development Indicator published in 2019. Descriptive and regression analyses were used as the estimation techniques. The findings of the study revealed that the coefficient value of LFDI is 0.633506 and its p-value is 0.0002 implying that a unit increase in LFDI will increase LGDP with the value of 0.633506. The coefficient value of RINTR is 0.004127 with p-value of 0.310 indicating that a unit increase in real interest rate will increase gross domestic product, but it is not significant. Also, LDI coefficient value is 1.758036 with p-value of 0.0688 implying that a unit increase in domestic investment will increase gross domestic product positively with the value of 1.758036 which is significant at 10% but not significant at 5% alpha level. The coefficient value of exchange rate is 0.835206 with the p-value of 0.0000 signifying that exchange rate is positive and significant to economic growth. It was concluded that foreign direct investment was positive and significant to economic growth of Nigeria while the domestic investment was also positive but not significant at 5% alpha level.

Effects of ozone-treated domestic sludge on hydroponic lettuce growth and nutrition

Here, the ozone-treated domestic sludge was diluted up to four different multiples and utilized as a nutritional source for hydroponic lettuce growth. Additionally, lettuce was cultured using the modified Hoagland nutrient solution as a control. The effects of ozone-treated domestic sludge on lettuce growth and nutrition were studied. Results showed that the lettuce treated with modified Hoagland inorganic nutrient solution had increased leaf number, plant height, fresh weight and dry weight compared to those treated with the ozone-treated domestic sludge dilution （P〈0.05）. However, the lettuce cultivated with the 2-fold ozone-treated sludge dilution showed significantly higher （P〈0.05） contents of chlorophyll, soluble sugar and ascorbic acid （Vc） compared to that treated with modified Hoagland nutrient solution. And the nitrate concentration in the lettuce cultured with the 2-fold ozone-treated sludge dilution was 53.93% less than that cultured with the modified Hoagland nutrient solution, which was a significant improvement （P〈0.05）. This study suggested that the 2-fold ozone-treated sludge dilution is optimal for lettuce hydroponic nutrient requirements.

Correlation Analysis between Economic Growth and Environmental Quality

With the rapid development of the economy,China’s environment has been damaged severely,which has attracted much attention from scholars and the local government.The concept of green development has been an underlying trend since 2012,and it is of great significance to explore the relationship between economic growth and environmental quality.Huzhou is a prefecture-level city under the jurisdiction of Zhejiang Province,and it is one of the 27 cities in the central area of the Yangtze River Delta.In recent years,this city develops well not only in economic development but also in maintaining a green environment.In the paper,the back propagation neural network is used to evaluate the local environmental quality.Meanwhile,the panel model is exploited to analyze the relationship between economic growth and environmental quality.All the data presented in the paper range from the year 2008 to 2018.Theoretical analysis indicates that the evaluation value of environmental quality,the emissions of industrial SO2,and waste water exhibit an inverted U-shaped relationship with economic growth.As for the regression results,the inflection point of income in the environmental Kuznets curve of the model which takes the evaluation value of the environmental quality as a dependent variable is higher than that of the model which takes the SO2 emission as an independent variable.The research result would help the local government to take appropriate countermeasures to improve the environment and economy.

Institutional Quality,Foreign Aid and Economic Growth in Recipient Countries

Foreign aid is an important aspect of China’s Belt and Road Initiative (BRI)for enhancing two-way cooperation with BRI countries. Based on the panel data of China’sforeign aid over the period 2000-2014, this paper employs the Worldwide GovernanceIndicators (WGI) to conduct an empirical study on the economic growth effects of China’sforeign aid and recipient countries’ institutional quality with the endogeneity of aid takeninto account. Results of our empirical study suggest that (i) China’s foreign aid, especiallyinfrastructure aid, can effectively promote economic growth in recipient countries;(ii)sound institutional development offers an important assurance for economic growth inrecipient countries;(iii) sample-specific regression reveals that the institutional quality ofrecipient countries can significantly influence the economic growth effects of China’s foreignaid, especially economic infrastructure aid for recipient countries in Asia and Europe.To improve aid effectiveness and quality, China needs to improve aid structure, superviseaid program implementation, and mitigate the impact of institutional risks in recipientcountries.

Governance Quality,Public Expenditure Efficiency,and Economic Growth

In this paper,we first examine the impact of governance quality on public expenditure efficiency.Then,we try to determine the effect of these expenditures on economic growth.Our starting point is the idea that public expenditure efficiency of a government program is significantly affected by the country’s governance quality.In other words,changes in government expenditure and the returns they generate on a government program depend on governance quality.Our sample consists of 36 countries observed over the 1996 to 2020 period.This period is known by a significant transition of political regimes.Our research model links government expenditure with the returns generated in a country in a given sector.In this model,we introduce the governance variable to examine the impact of government expenditure on returns on a government program in terms of schooling rates and life expectancy.The results indicate that governance quality affects expenditure structure and that efficiency of this expenditure positively correlates with a better governance quality as measured by corruption control and government efficiency.We also found that efficient expenditure has a positive impact on economic growth.

Nexus Between Financial Liberalization, Balance Of Payment And Economic Growth In Nigeria

The objectives of this paper are to examine the nexus between financial liberalization,balance of payment and economic growth in Nigeria.The scope of this study due to data availability,especially on measures of balance of payment,covers the period of 1986-2017.This study adopts econometrics techniques of analysis by using Panel Unit Root Tests and Co-integration analysis which is used to determine the long run relationship among economic variables.To test the co-integration relationship this study followed the system proposed by Pedroni(1991)who expands the Engle and Granger[9]two stage technique to heterogeneous board information structure.The study adopts annual time series secondary data for the period of 1986 to 2017.Balance of payment,Official Exchange Rate,Inflation rate(%),Balance of trade,Trade openness,Real Gross Domestic Product growth,and Term of Trade,all data used were obtained from the World Development Indicators.The findings of this study revealed that an increase in exchange rate,interest rate,inflation rate,and trade openness have negatively affect economic growth.Hence,changes or movements in these variables do not necessarily prompt the liberalization decision in the real sector.Therefore,the need to address balance of payment is important,in accordance with the low rate of development in Nigeria.We therefore,recommend that government should monitor both Fiscal and Monetary policies’variables that can significantly influence economic growth in Nigeria.That is,adequate balance of payment that can encourage appropriate financial liberalization should be put in place with,Official Exchange Rate,Inflation rate(%),Balance of trade,Trade openness.

Domestic Savings,Investment,and Economic Growth:an Empirical Evidence from Nepal using VEC Model

This study examines the relationship between domestic savings,investment,and economic growth in Nepal by using time series data covering from the period 1975 to 2019.The vector error correction model(VECM)has been used to investigate the long-run and short-run causal relationship between the variables.The Johansen cointegration test results confirmed that there is a long-run relationship between savings,investment,and economic growth.Therefore,further analysis has to be set for the VEC model to analyze both long-run and short-run causality.The VECM equation result is-0.1363 which is the adjustment speed of disequilibrium towards the equilibrium in long run.The coeffi cient of savings and investments are positive with economic growth which also indicates that both variables have a positive impact on economic growth in the short run.The results of the Jarque-Bera test show the residual distribution is normally distributed.For the model stability test,the study performed recursive estimation applying CUSUM and CUSUM of square,and both tests move within the 5 percent level of upper and lesser bound significance indicating that the model is stable over the observation period.Overall,the study suggests that in Nepal,domestic savings and investment growth have a positive contribution to economic growth.The central bank,planning commission,and ministry of finance should focus on stimulating the capital formation and productive sector investment for sustainable economic growth in Nepal.

China's economic growth pushed by domestic demand and relevant measures

By contrast to a slowdown in the world economy, China kept up a rapid growth rate, a relatively high quality of growth and low inflation for the year 2001. This is mainly due to the result of proactive fiscal policies that the Chinese Government adopted to stimulate domestic demand. Domestic demand can be divided into investment demand and consumption demand,

The Effect of Three Culture Methods on Intensive Culture System of Pacific White Shrimp (Litopenaeus vannamei)

Different culture methods may affect the intensive culture system of Pacific white shrimp(Litopenaeus vannamei) regarding water quality and growth and economic performance.This study evaluated the potential effects of three culture methods through cultivation of juvenile shrimps under consistent tank management conditions for 84 d.The three methods involved shrimp cultivation in different tanks,i.e.,outdoor tanks with cement bottom(mode-C),greenhouse tanks with cement bottom(mode-G) and outdoor tanks with mud-substrate(mode-M).Results showed that water temperature was significantly higher in mode-G than that in mode-C(P < 0.05).In contrast to the other two treatments,mode-M had stable pH after 50 d cultivation of shrimps.In the mid-late period,the average concentrations of TAN,NO2-N,DIP and COD were significantly lower in mode-M and mode-G compared with those in mode-C(P < 0.05).Despite lack of differences in the final shrimp weight among different treatments(P > 0.05),mode-M had significantly higher shrimp yield,survival rate and feed conversion rate(P < 0.05) than other modes.There were significant differences in revenue and net return among different treatments(P < 0.05).These demonstrated that the treatments of mode-G and mode-M were conductive to the intensive culture system of L.vannamei.

Present situation and countermeasure research of economic structure of Shaanxi Province

Economic structure is a significant factor impacting economic growth and economic growth quality. In this paper, the present status of economic structure of Shaanxi Province is analyzed, and available primal problem is indicated. There have been a lot of problems in economic structure of Shaanxi Province, mainly including slow tertiary industry development, comparatively grave unbalance of light and heavy industries proportion, lagged development in high and new technology industries, high industry convergence degree, low scale effect, slow agriculture expanding and so on. Meanwhile, homologous countermeasure is given in this text： we should develop tertiary industry with tourism as the leading role energetically to promote industrial hierarchy, impulse structural rationalization of foreign trade through international cooperation and competition, accelerate the industrialization, promote industrial structure upgrade, develop the high and new technology industries quickly, accelerate the promotion of industry scale effect and expedite expansion of industry colony. We should also develop superior industry, reduce industry convergence degree, and develop the agriculture energetically to promote the industrialization and modernization of agriculture. These points are given in the interest of supplying gist and reference to government in industrial structure adjusting and policy making.

Domestic, External Demands：Dual-Engines of China＇s Growti

China＇s economic growth has been driven by the dual-engine of domestic demand and external demand. Among which, domestic demand is the main engine originated from China＇s huge domestic market. Due to the advantage of openness, external demand has a growing contribution to economic growth. For a long term, China will remain in the stage of rapid industrialization, urbanization, marketization and internationalization, therefore China will further expand its domestic consumption and external demand. The undergoing institutional reform will also contribute to the coordinated development of domestic demand and external demand.

FDI＇s Spillover Effects on China＇s Growth Quality

Using panel data of 29 regions in China from 1999 to 2007, this paper presents a systematic evaluation of how FDI＇s spillover effects impact the quality of China＇s indigenous econotnic growth, Research outcomes suggest that technology transfers and diffusion have a positive effect on indigenous growth quality. Spitlover effects （mainly competition effect） have primarily negatively affected indigenous growth quality. The effect on indigenous growth quality is positive only in sub-samples with high foreign capital concentration and ,,hen the spillover effect is similar to the technology transfer and diffusion effect brought about by localization. It is also found that technology gaps, foreign capital concentration and value added ratio gaps are important factors affecting the impact of technology transfer and diffusion on indigenous economic growth.
