A review of China's energy consumption structure and outlook based on a long-range energy alternatives modeling tool

China＇s energy consumption experienced rapid growth over the past three decades, raising great concerns for the future adjustment of China＇s energy consumption structure. This paper first presents the historical evidence on China＇s energy consumption by the fuel types and sectors. Then, by establishing a bottom-up accounting framework and using long-range energy alternatives plan- ning energy modeling tool, the future of China＇s energy consumption structure under three scenarios is forecast. According to the estimates, China＇s total energy con- sumption will increase from 3014 million tonnes oil equivalent （Mtoe） in 2015 to 4470 Mtoe in 2040 under the current policies scenario, 4040 Mtoe in 2040 under the moderate policies scenario and 3320 Mtoe in 2040 under the strong policies scenario, respectively, lower than those of the IEA＇s estimations. In addition, the clean fuels （gas, nuclear and renewables） could be an effective alternative to the conventional fossil fuels （coal and oil） and offer much more potential. Furthermore, the industry sector has much strong reduction potentials than the other sectors. Finally, this paper suggests that the Chinese government should incorporate consideration of adjustment of the energy consumption structure into existing energy policies and measures in the future.

Comparison among the Consumption Structures of Different Income Groups of Urban Residents in Guangxi Based on ELES Model

According to the household consumption data of urban residents in Guangxi Statistical Yearbook in the year 2009, the ELES (Extended Linear Expenditure System) is used to analyze the consumption structure, the propensity to consume, and the consumer flexibility of urban residents in Guangxi Zhuang Autonomous Region of China in the year 2008. Result shows that urban residents in Guangxi has relatively low propensity to consume. And their consumption, especially the middle and low-income families, is mostly concentrated in food, cloth, lodging and other basic necessities of life, which account for more than a half of their income. Based on this, corresponding suggestions are put forward to enlarge the consumption demand of urban residents in Guangxi, such as increasing the regulation of income redistribution, minimizing the gap between the rich and the poor, enhancing the overall consumption level, cultivating the consumption hot spots for the urban residents, and actively guiding the enjoyable consumption.

It is urgent to significantly reduce greenhouse gas emissions to actively deal with global warming.This paper investigates Shandong Province,a typical province of energy consumption,as the research object,aiming to optimize total energy consumption and consumption structure in the future planning year.This paper constructs a methodological system to optimize energy consumption structure in Shandong Province,using a scenario combination of system dynamics(SD)prediction and analysis based on the coupling of key scenario elements affecting different energy consumption from different perspectives.Structural equation modeling and SD sensitivity analysis indicate an overlap between key factors restricting energy consumption.Pairing the key scenario factors can better reflect the internal mechanism of energy consumption development.Based on this,21 scenarios based on different combinations of the key elements are constructed.Through SD prediction and analysis,the most suitable scenario mode for optimizing energy consumption structure in Shandong Province is selected.This paper provides a suitable development range for the average gross domestic product growth rate,the proportion of secondary industry,energy consumption intensity of secondary industry,and the urbanization rate for Shandong Province.This paper can provide a reference for similar research and the government in formulating the optimization scheme of energy consumption structure.

Empirical Study on Effects of Different Types of Urbanization on Consumption Structure of Rural Residents in China

In the process of urbanization,there are problems of decline in rural population,shrinkage of rural area,and constant increase in the per-capita net income of rural residents. These problems have brought about new characteristics and changes to the consumption structure of rural residents. This paper divided the urbanization into population urbanization,industrial urbanization and land urbanization. Using the panel data of 31 provinces in 2004-2013,it established the dynamic panel model and analyzed the effects of different types of urbanization on the consumption structure of rural residents. Results indicated that population urbanization exerts a negative effect on development-oriented consumption expenditure of rural residents,while it exerts a positive effect on enjoyment consumption expenditure; the industrial urbanization exerts a negative effect on the consumption expenditure of rural residents,while it exerts a positive effect on clothing and transportation communication consumption of rural residents; land urbanization exerts a negative effect on medical care expenditure in enjoyment consumption of rural residents. In view of these problems,it came up with recommendations,including stimulating the development of rural consumer market,liberating the consumption potentiality of rural areas,making clear emphasis points of different types of urbanization,avoiding promoting the urbanization in a blind manner,and adjusting the development of different types of urbanization on the basis of the consumption demands of rural residents.

Research on the Impact of the Pension Insurance System on the Optimization of the Consumption Structure of Rural Families

Presently,the growth of residents’consumption is slowing,which necessitates the expansion of domestic demand.Against this backdrop,research on the impact of pension insurance on the optimization of the consumption structure in rural areas not only facilitates the welfare of rural residents and improves their consumption structure but also boosts the sustainable and healthy development of the Chinese economy.This paper applies China Family Panel Studies(CFPS)micro-data in 2018 and adopts Propensity Score Matching(PSM)to research the impact of China’s pension insurance system on the consumption structure in rural areas and its heterogeneity.This paper draws a conclusion at four levels.First,pension insurance effectively optimizes the consumption structure in rural areas,increases the current overall consumption level by 0.0024 percent,and objectively releases the consumption potential in rural areas.Second,participation in pension insurance enhances the overall consumption level of rural families in eastern China,central China,and northeastern China by 0.08 percent,0.146 percent,and 0.0446 percent respectively,yet,that inhibits the overall consumption level of rural families in rural areas in western China by 0.1057 percent.Third,from eastern China to western China,with regard to pension insurance,as its impact on consumption shifts from a higher level to a lower level,its impact on the optimization of consumption structures sinks to a lower level.Fourth,in terms of major factors,age(older),matrimonial res(married),years of education(longer),health(poor),and the number of family members(small)contribute to the stronger willingness to participate in pension insurance.

Analysis on Carbon Emissions from Energy Consumption in Agriculture and Reduction Measures in Guangdong Province

[Objective] The aim was to study CO2 emissions from energy consumption in agricultural production in Guangdong Province and put forward feasible reduction measures.[Method] Based on the data from China Energy Statistical Yearbook and Guangdong Statistical Yearbook,CO2 emissions from agricultural energy use in Guangdong Province from 2000 to 2009 was estimated by using the formula of carbon emissions recommended by Intergovernmental Panel on Climate Change (IPCC),and corresponding reduction measures were put forward.[Result] With the rapid increase of agricultural output and energy consumption,CO2 emissions from energy consumption in agricultural production in Guangdong Province showed increasing trend from 2000 to 2009,that is to say,increasing from 423.63×104 t C million tons in 2000 to 605.99×104 t C in 2009,with annual growth rate of 4.1%.Meanwhile,carbon emissions intensity during energy consumption in agriculture went down in recent ten years,in other words,decreasing from 0.424 t C/×104 yuan in 2000 to 0.301 t C/×104 yuan in 2009,and its annual decreasing rate was 3.7%.The variation of CO2 emissions from energy consumption in agriculture mainly resulted from the increase of agricultural output,improvement of energy utilization efficiency,high carbonization in agricultural energy consumption structure and so forth.Therefore,in order to reduce CO2 emissions from energy consumption in agriculture,it is necessary to vigorously develop rural renewable energy,develop and popularize advanced technology for energy utilization,advance the energy conservation of agricultural machines,establish and improve the macroeconomic control mechanism for carbon emissions from the energy consumption in agricultural production in the further.[Conclusion] The study could provide references for the establishment of policy about reducing carbon emissions from agricultural energy consumption in Guangdong Province.

Research on Energy Consumption of Traditional Natural Villages in Transition: A Case Study in Zhejiang Province

Traditional agriculture is in the direction of increasing integration of the primary industry, secondary industry, and tertiary industry in Zhejiang province. A survey was undertaken on energy consumption of traditional natural villages by taking Anji Ligeng village for an example. This paper firstly studied rural buildings, rural family structure, occupants’ activity and the usage of household appliances in the form of a questionnaire. Then, the household energy resource structure and energy consumption structure were analyzed and compared with other surveys. The results show that, the electric energy consumption was 6 kWh/(m2•a), which was far less than urban residential household. In rural household energy resource structure, the proportion of non-commercial energy resource was higher than commercial energy resource. Firewood accounted for 83%, electricity for 12%, LPG for 3% and solar energy for 2%. In building energy consumption structure, cooking and hot water took up 33%, appliances 31%, lighting 20%, heating 12%, cooling 4%. In all influential factors, frequently used area, number of air conditioner per household and building function were obviously correlated with energy consumption;income, building shape factor and window to wall area ratio had no correlation with energy consumption in the low energy consumption area.

Intergenerational Comparative Study on Consumption of Migrant Workers in China

Based on China urban labor survey data of 2016, this paper investigates the differences in consumption level and structure between the new and previous generation rural migrant workers in China and identifies the determinants of migrant workers' consumption. According to descriptive analysis, the new-generation migrant workers' households spend 26% more on an annual per capita basis compared with their previous generation. More specifically, the new-generation migrant workers' households spend 33% more on clothing, food, housing and travel, and 10% more on healthcare on an annual per capita basis compared with their previous generation, while their per capita spending on education is only 73% that of their previous generation. Result of regression analysis shows that with other factors under control, the new-generation migrant workers' households spend 14.9% more on clothing, food, housing and travel compared with their previous generation, and their per capita gross consumption is 10.9% higher than that of their previous generation. Consumption elasticity for clothing, food, housing and travel among the new-generation migrant workers' households and their overall consumption elasticity are both significantly higher than those of the previous generation migrant workers' households. Compared with their previous generation, the spending of the new-generation migrant workers' households on clothing, food, housing and travel represents a higher share of their overall consumption, and the share of their educational consumption is even lower.

Energy consumption hierarchical analysis based on interpretative structural model for ethylene production

Interpretative structural model(ISM) can transform a multivariate problem into several sub-variable problems to analyze a complex industrial structure in a more efficient way by building a multi-level hierarchical structure model. To build an ISM of a production system, the partial correlation coefficient method is proposed to obtain the adjacency matrix, which can be transformed to ISM. According to estimation of correlation coefficient, the result can give actual variable correlations and eliminate effects of intermediate variables. Furthermore, this paper proposes an effective approach using ISM to analyze the main factors and basic mechanisms that affect the energy consumption in an ethylene production system. The case study shows that the proposed energy consumption analysis method is valid and efficient in improvement of energy efficiency in ethylene production.

Modeling and scenario prediction of a natural gas demand system based on a system dynamics method

Based on the study of the relationship between structure and feedback of China’s natural gas demand system, this paper establishes a system dynamics model. In order to simulate the total demand and consumption structure of natural gas in China, we set up seven scenarios by changing some of the parameters of the model. The results showed that the total demand of natural gas would increase steadily year by year and reach in the range from 3600 to 4500 billion cubic meters in 2035. Furthermore, in terms of consumption structure, urban gas consumption would still be the largest term, followed by the gas consumption as industrial fuel, gas power generation and natural gas chemical industry. In addition, compared with the population growth, economic development still plays a dominant role in the natural gas demand growth, the impact of urbanization on urban gas consumption is significant, and the promotion of natural gas utilization technology can effectively reduce the total consumption of natural gas.

Consumption Structure of Migrant Worker Families in China

This study draws on a survey of migrants in 12 cities across four major urbanizing areas in China and investigates the structure of migrant worker families＇urban and rural consumption. The results show that the structure of migrant worker families＇ consumption has been dominated by survival consumption. These families tend to live frugally in cities while engaging in conspicuous consumption in their rural hometowns. The structure of migrant worker families＇consumption is mainly shaped by their income stability and wealth levels rather than their current income level. Moreover, migrant worker families with high educational levels and those who intend to settle permanently in cities are likely to allocate substantial expenditure to status and hedonic consumption and to upgrade their urban consumption structure.

Relationship Between Economic Growth and Water Environmental Quality of Anshan City in Northeast China

Based on the decomposition model of environmental quality and univariate regression model,the relationships of industrial wastewater drainage with economic scale,economic structure,and technological level in Anshan,a mining city in Northeast China,were studied. The results showed that,due to scale effect,the drainage of three important industrial wastewater pollutants(COD,NH3-N and petroleum) increased 8505t,671t and 384t,respectively,and due to structure effect,those pollutants drainage increased 3996t,174t and 120t from 2001 to 2006. While due to technological effect,the drainage of COD,NH3-N and petroleum reduced 4452t,458t and 331t,and due to cross effect,those pollutants drainage reduced 7270t,575t and 476t simultaneously. Meantime,the relationships between household consumption structure and domestic sewage discharge were analyzed,and domestic sewage discharges in different income levels were also compared. The results showed that,the domestic sewage discharges would increase 376t with 1000 yuan(RMB) increased in the traffic and communication consumption,and they would be 344t,219t,428t,1873t,respectively,in housing consumption,food consumption,medical consumption,miscellaneous commodity consumption. The proportion of domestic sewage discharge increased for high income residents significantly,but reduced for lower income residents. The industrial wastewater pollutants drainage tends to be reduced by technical progress,while domestic sewage discharge will be a more important factor for urban water environment quality.

Theoretical Logic and Empirical Facts of Consumption Structure Upgrade and Domestic Value Chain Circulation under the New Development Pattern

Under the new development pattern,this paper explores the characteristic tendencies and intergenerational changes of consumption structure upgrade(CSU)as well as the theoretical logic and empirical paradigm affecting the domestic value chain circulation.This paper constructs a region-industry decomposition framework for domestic value chain circulation based on backward demand to explore the impact of CSU on domestic value chain circulation.The results show that:first,CSU can optimize the structure of domestic value chain circulation and strengthen inter-regional value chain linkage;second,CSU promotes domestic value chain circulation through innovation drive,resource optimization and industrial coupling;finally,the domestic value chain circulation effect caused by CSU may be constrained by market segmentation,and accelerating regional economic integration across a country can help build up the main position of domestic value chain.

Thoughts on the Development of Characteristic Cultural Tourism Products of the Republic of Vanuatu

Vanuatu is an underdeveloped country,but it is rich in tourism resources and has become an increasingly popular tourist destination.Tourism is one of the pillar industries of national economy.At present,the core component of Vanuatu’s tourism consumption structure is the basic elements based on accommodation,transportation and catering.However,the proportion of shopping,sightseeing and entertainment,which are factors of tourism value-added consumption,is very low.Therefore,it is urgent to improve efficiency and quality of tourism.This study suggested that Vanuatu develop characteristic cultural tourism products in multiple dimensions,build its characteristic cultural tourism pedestrian streets,make cultural tourism products with food tourism as the theme,create a brand series of Vanuatu characteristic tourist souvenirs,design the characteristic homestay experience with "slow tourism" as the core and optimize the structure of tourism consumption in Vanuatu to improve its cultural influence and the level of modern service industry and realize the optimization and upgrading of the industrial structure.

Theory, System and Policy Proposals on New Factor Supply for Higher-Stage Development in China

By introducing the knowledge sector, this paper has structurally redefined the production function and on such a basis, analyzed the role of new factor supply in China's economic transition and reached the following conclusions: 1) The supply of new production factors represented by knowledge sector has become the dominant force that decides whether China can overcome the barrier of structural deceleration, and achieve sustained growth and stride into a higher stage of development; 2) In the context of rising urban household income and upgrading demand, the knowledge sector has emerged, encompassing science and technology, culture, health and sports that contribute to enhanced "human capital in the broad sense", and the production and consumption process of the knowledge sector is also the process of human capital improvement and endogenous innovation; 3) Aside from its endogeneity, the knowledge sector creates spillover effects that will revitalize traditional industries and services, remove the barriers between consumption and production, and promote structural transition and economic upgrade for innovationdriven growth; 4) In the context of flagging growth driven by material capital, great importance should be attached to the contribution of consumption to human capital in the broad sense and promote the interactive upgrade of consumption and production structures, which are the key to overcoming the bottlenecks of development.
