Impact of Growing Income Inequality on Sustainable Development in China: A Provincial-level Analysis

Abstract

A growing body of literature has documented the rapidly increasing income disparities that accompanied China's economic growth in the 1980s and 1990s, and the driving factors behind this. Growing income inequality in its turn may have important implications for the accumulation of physical capital, human capital, and natural capital and as a consequence for sustainable economic development. The purpose of this paper is to investigate the potential impact of income inequality on savings, human resources and the environment in China. It starts with an overview of the different causal mechanisms through which income inequality may affect the accumulation of physical capital, human capital, and natural capital, and discusses to what extent these causal relationships may be relevant in the case of China. Next, provincial data for the year 2002 are used to explore the relationship between income inequality and different elements of sustainable development in China. It is found that income inequality does not affect aggregate savings levels. Rising inequality, however, contributes to lower health and possibly also to higher fertility levels. It also lowers the use of chemical fertilizers in agriculture and therefore is likely to reduce water pollution. Other types of environmental degradation are not affected.

Towards Sustainable Urban Environmental Management in Jiangyin city,East China

Abstract

Dramatic economic and social changes have taken place in Jiangyin city due to rapid and uneven urbanization and industrialization. The environmental degradation has followed driven by these changes since the 1980's. With the pressures and effects of environmental deterioration, the city has implemented environmental management to hold back the trends of negative environmental changes. From the viewpoint of systems, DPSER is a good model for urban environmental changes to understand the causes, pressure, state, effect, existing responses and future action strategies. We took Jiangyin city, a developed city in South Jiangsu province, East China, as an example, and analyzed the characteristics of environmental changes and urban responses using DPSER model. Some operational strategies have been put forward to direct the city environmental management towards a sustainable road step by step.     

News

Western China has lagged a lot in terms of industrial structure and economic development, compared with the national average. And China announced its target of CO₂ emission reduction, i.e. by 2020, CO₂ emission per GDP will drop by 40–45% compared with 2005. The target will be incorporated into China’s long-term industrial planning. Against this background, this paper will make a comprehensive examination of the industrial development of Western China, aiming to discover a green and compatible way. First, we analyze the spatiotemporal evolution of regional industrial structure for the period 2000–2010. Second, we try to discover the industrial structure optimization path for Western China by employing the Vector Auto Regression model. Lastly, we try to provide some advice and suggestions for further industrial development in Western China. Our examination shows that further industrial development in Western China should pay full attention to resource conservation and recycling, and develop on a green and compatible path.     

Risk Assessment of Carbon Sequestration for Terrestrial Ecosystems in China

Abstract

Climate change will alter the capacity of carbon sequestration, and the risk assessment of carbon sequestration for terrestrial ecosystems will be helpful to the decision-making for climate change countermeasures and international climate negotiations. Based on the net ecosystem productivity of terrestrial ecosystems simulated by Atmosphere Vegetation Integrated Model, each grid of the risk criterion was set by time series trend analysis. Then the risks of carbon sequestration of terrestrial ecosystems were investigated. The results show that, in the IPCCSRES-B2 climate scenario, climate change will bring risks of carbon sequestration, and the high-risk level will dominate terrestrial ecosystems. The risk would expand with the increase of warming degree. By the end of the long-term of this century, about 60% of the whole country will face the risk; Northwest China, mountainous areas in Northeast China, middle and lower reaches plain of Yangtze River areas, Southwest China and Southeast China tend to be extremely vulnerable. Risk levels in most regions are likely to grow with the increase of warming degree, and this increase will mainly occur during the near-term to mid-term. Northwest China will become an area of high risks, and deciduous coniferous forests, temperate mixed forests and desert grassland tend to be extremely vulnerable.     

On the Regional Coordinated Development Between Tourism Human Resource and Tourism Industry in China

Abstract

Tourism is one of the typical labor intensive industries and tourism human resource (HR) is the main factor for regional discrepancy of tourism industry. The paper takes China as research region and evaluates the level of tourism HR and the level of tourism industry of 31 provinces respectively. First, the paper constructs evaluation index of regional tourism industry and tourism HR. Then, the paper gets the evaluation scores of every province by applying the principal components analysis and statistical package for the social sciences processing. Second, the paper builds the tourism development-tourism HR matrix and divides the matrix into four quadrants. Finally, the paper points out the problems of tourism HR that exist in the 31 provinces and puts forward development strategy.     

Analysis of the Energy Embodied in Foreign Goods Trade of China

Abstract

In recent years, scientists have been increasingly interested in the energy embodied in traded goods among countries. In this article, the direct energy intensities in various economic sectors of China were calculated with the data of energy consumption and output value of each sector, and the input–output table was used to estimate the external energy consumption. The total energy intensity of all sectors was then obtained. From the data of international trade, the energy embodied in goods trade of China was estimated for the period of 1994–2001. During this period, the average energy intensity of imported goods was always higher than that of exported ones. As a country with a surplus in international goods trade, China actually imported net embodied energy in the past few years. The net embodied energy imported was at the same magnitude of the imported energy in the form of fossil fuels.     

Policy options to promote Chinese new energy vehicles consumption

Inspired by the green revolution, new energy vehicles (NEVs) provide a fresh, alternative mode of transportation for Chinese consumers that reduce their reliance on traditional, gasoline/diesel-based cars. However, despite strong government support for NEVs in China, the level of uptake by consumers remains slow. Using Shanghai as a case study, this article provides a much-needed insight into local consumers’ motivations to invest in NEVs through a survey of 100 Shanghai residents. Results indicate that current NEV promotion policies do not have a significant impact on the cognitive trade-off of NEV consumption under the “Integrated Consumer Behavior Model,” mainly due to inconvenient charging facilities, technical concerns regarding battery, higher prices, and wait-and-see attitudes regarding the pilot policy environment. Drawing on experiences from Sweden and New Zealand, this research serves to enhance knowledge on consumer attitudes towards NEVs and assist policy makers in developing more effective green consumption promotion campaigns in the future.     

Variation characteristics of atmospheric methane and carbon dioxide in summertime at a coastal site in the South China Sea

● Diurnal patterns of CH₄ and CO₂ are clearly extracted using EEMD. ● CH₄ and CO₂ show mid-morning high and evening low patterns during sea breezes. ● Wind direction significantly modulates the diurnal variations in CH₄ and CO₂. Methane (CH₄) and carbon dioxide (CO₂) are the two most important greenhouse gases (GHGs). To examine the variation characteristics of CH₄ and CO₂ in the coastal South China Sea, atmospheric CH₄ and CO₂ measurements were performed in Bohe (BH), Guangdong, China, in summer 2021. By using an adaptive data analysis method, the diurnal patterns of CH₄ and CO₂ were clearly extracted and analysed in relation to the sea breeze (SB) and land breeze (LB), respectively. The average concentrations of CH₄ and CO₂ were 1876.91 ± 31.13 ppb and 407.99 ± 4.24 ppm during SB, and 1988.12 ± 109.92 ppb and 421.54 ± 14.89 ppm during LB, respectively. The values of CH₄ and CO₂ during SB basically coincided with the values and trends of marine background sites, showing that the BH station could serve as an ideal site for background GHG monitoring and dynamic analysis. The extracted diurnal variations in CH₄ and CO₂ showed sunrise high and sunset low patterns (with peaks at 5:00–7:00) during LB but mid-morning high and evening low patterns (with peaks at 9:00) during SB. The diurnal amplitude changes in both CH₄ and CO₂ during LB were almost two to three times those during SB. Wind direction significantly modulated the diurnal variations in CH₄ and CO₂. The results in this study provide a new way to examine the variations in GHGs on different timescales and can also help us gain a better understanding of GHG sources and distributions in the South China Sea.     

Formation of secondary inorganic aerosol in a frigid urban atmosphere

•Harbin showed relatively high threshold RH (80%) for apparent increase of SOR. •The observed SOR were at the lower end of the ratios from Beijing’s winter. •Temperature-dependent increase of NOR was sharper than that of SOR. • NOR increased with stronger biomass burning impact but SOR was largely unchanged. Formation of secondary inorganic aerosol (SIA) was investigated during a six-month long heating season in Harbin, China. Enhanced sulfate formation was observed at high relative humidity (RH), with the same threshold RH (80%) for both colder and warmer measurement periods. Compared to wintertime results from Beijing, the threshold RH was considerably higher in Harbin, whereas the RH-dependent enhancement of sulfur oxidation ratio (SOR) was less significant. In addition, the high RH events were rarely encountered, and for other periods, the SOR were typically as low as ~0.1. Therefore, the sulfate formation was considered inefficient in this study. After excluding the several cases with high RH, both SOR and the nitrogen oxidation ratio (NOR) exhibited increasing trends as the temperature increased, with the increase of NOR being sharper. The nitrate to sulfate ratio tended to increase with increasing temperature as well. Based on a semi-quantitative approach, this trend was attributed primarily to the temperature-dependent variations of precursors including SO₂ and NO₂. The influence of biomass burning emissions on SIA formation was also evident. With stronger impact of biomass burning, an enhancement in NOR was observed whereas SOR was largely unchanged. The different patterns were identified as the dominant driver of the larger nitrate to sulfate ratios measured at higher concentrations of fine particulate matter.
