China’s Potential Economic Growths during 2015-2025 under Different Scenarios~

China has entered a crucial period of further growth and restructuring that will last until 2025. Based on a review of the major factors affecting China＇s potential economic growth, this paper has created an integrated economic system model consisting of system dynamics, econometrics, and input-output for the forecast of China＇s economic size and structure by 2025. Analysis shows that prior to 2025, China will be able to maintain a potential annual economic growth rate of 5.7%-7.2%. Faced with an international environment of a possible slowdown of advanced economies and diminishing demographic dividends, China needs to further expedite its urbanization process, enhance R＆D and education spending, increase total factor productivity （TFP）, vigorously develop the tertiary sector, and expand consumption in order to achieve the optimistically estimated growth of 6.6%-7.4% during the period of 2015-2025. Economic growth should be accompanied by the upgrade of industry structure and improvement of investment and consumption structures.

Multi-model comparison of CO2 emissions peaking in China:Lessons from CEMF01 study

The paper summarizes results of the China Energy Modeling Forum's(CEMF)first study.Carbon emissions peaking scenarios,consistent with China's Paris commitment,have been simulated with seven national and industry-level energy models and compared.The CO2 emission trends in the considered scenarios peak from 2015 to 2030 at the level of 9e11 Gt.Sector-level analysis suggests that total emissions pathways before 2030 will be determined mainly by dynamics of emissions in the electric power industry and transportation sector.Both sectors will experience significant increase in demand,but have low-carbon alternative options for development.Based on a side-by-side comparison of modeling input and results,conclusions have been drawn regarding the sources of emissions projections differences,which include data,views on economic perspectives,or models'structure and theoretical framework.Some suggestions have been made regarding energy models'development priorities for further research.

The relationship between international crude oil prices and China＇s refined oil prices based on a structural VAR model

With the frequent fluctuations of international crude oil prices and China＇s increasing dependence on foreign oil in recent years, the volatility of international oil prices has significantly influenced China domestic refined oil price. This paper aims to investigate the transmission and feedback mechanism between international crude oil prices and China＇s refined oil prices for the time span from January 2011 to November 2015 by using the Granger causality test, vector autoregression model, impulse response function and variance decomposition methods. It is demonstrated that variation of international crude oil prices can cause China domestic refined oil price to change with a weak feedback effect. Moreover, international crude oil prices and China domestic refined oil prices are affected by their lag terms in positive and negative directions in different degrees. Besides, an international crude oil price shock has a signif- icant positive impact on domestic refined oil prices while the impulse response of the international crude oil price variable to the domestic refined oil price shock is negatively insignificant. Furthermore, international crude oil prices and domestic refined oil prices have strong historical inheri- tance. According to the variance decomposition analysis, the international crude oil price is significantly affected by its own disturbance influence, and a domestic refined oil price shock has a slight impact on international crude oil price changes. The domestic refined oil price variance is mainly caused by international crude oil price disturbance, while the domestic refined oil price is slightly affected by its own disturbance. Generally, domestic refined oil prices do not immediately respond to an international crude oil price change, that is, there is a time lag.

Modification of Costanza's model of valuing ecosystem services and its application in China

In the past,evaluations of ecosystem functions were mostly based on Costanza's model,whereas the spatial,quality and temporal characteristics of regional ecosystems were not considered in the model.Focusing on these issues,coefficients of regional difference,spatial heterogeneity and willingness-to-pay(WTP)were established to modify Costanza's model,and a new comprehensive valuation model of ecosystem functions is proposed.The analytical results indicate that the comprehensive model could evaluate regional ecosystem functions in China accurately and provide more helpful information for decision-making.The empirical study on Zhangbei County in Hebei Province shows that the intensive human activities could limit the provision of ecosystem functions while the planned ecological programs might promote the restoration of ecosystem functions.

Three Models of English Education in China＇s Universities ——-A Historical Perspective

In the present paper, a comparison is made of the three formats in the history of EECU （English education in China＇s universities）. In the first period （1904-1949）, English education was conducted separately in government-managed educational institutions and in institutions sponsored by church-related organizations; English education was well-knit with both general education and specialty education; and self-motivating learning was encouraged. In the second period （1950-1966）, almost everything was tinted with a shady color of politics： A halt was addressed drastically to EEC （English education in China） in 1952. In the gradual recovery that started four years later, the second format was sawed and hammered, showing the following features： All non-government-mamaged institutions vanished from the stage; English was taught solely as a language or a system of verbal parts, almost deprived of all cultural loading. The third period （1978 onwards） has witnessed a barrier-free and rapid development of over three decades, resulting in the unprecedented pervasion of EECU. Yet in the third tbrmat, learners＇ efforts have turned wholly test-oriented, degenerating into the saddening disintegrity of learning as a process into isolated charges to the target of a test at a time; the ignorant reduction of the learning methods to ＂Vocabulary Booklets Plus Collections of Test Papers＂. Such a comparison not only provides a multi-dimensional perspective of EECU and a better understanding of it, but also offers some important experiences and lessons for the search of an effective solution to the pervasive problem of＂Time-Consumingness and Low-Efficiency＂.

How to Sustain the Rapid Growth of China's Economy

Can the rapid growth of China’s economy be sustained? How is it to be sustained? This has become a hot topic in recent years arousing worldwide attention. To understand the reason for this much talked about topic, we have to look at the past 30 years of China’s development, and how it has become an important force in the world economy. Whether

China's economic performance and prospects for the first half of 2009

China’s economic downturn has been brought under control with a series of stimulus policies,and the economy is in a critical period of stable recovery.In the first half of this year,its GDP growth reached 7.1%,and is expected to rise in the second half of the year.Overall,the annual growth rate for this year may exceed the goal of 8%. Maintaining growth remains a top priority of the next stage of macro-regulation,and China must steadfastly implement a proactive fiscal policy and moderately relaxed monetary policy.In maintaining growth and expanding domestic consumption,China should be patient,follow the laws of economic development,and properly balance the urgent economic growth priorities with long-term sustainable development.Macro-regulation should highlight transformation of growth pattern,strategic restructuring and improvement of economic efficiency.We should implement the policies that have been alrendy issued,and make policy preparations against emerging domestic and international situations and problems.

Temporal and spatial variability of the carbon cycle in the east of China's seas:a three-dimensional physical-biogeochemical modeling study

In the east of China＇s seas, there is a wide range of the continental shelf. The nutrient cycle and the carbon cycle in the east of China＇s seas exhibit a strong variability on seasonal to decadal time scales. On the basis of a regional ocean modeling system（ROMS）, a three dimensional physical-biogeochemical model including the carbon cycle with the resolution（1/12）°×（1/12）° is established to investigate the physical variations, ecosystem responses and carbon cycle consequences in the east of China＇s seas. The ROMS-Nutrient Phytoplankton Zooplankton Detritus（NPZD） model is driven by daily air-sea fluxes（wind stress, long wave radiation, short wave radiation, sensible heat and latent heat, freshwater fluxes） that derived from the National Centers for Environmental Prediction（NCEP） reanalysis2 from 1982 to 2005. The coupled model is capable of reproducing the observed seasonal variation characteristics over the same period in the East China Sea. The integrated air-sea CO_2 flux over the entire east of China＇s seas reveals a strong seasonal cycle, functioning as a source of CO_2 to the atmosphere from June to October, while serving as a sink of CO_2 to the atmosphere in the other months. The 24 a mean value of airsea CO_2 flux over the entire east of China＇s seas is about 1.06 mol/（m^2·a）, which is equivalent to a regional total of3.22 Mt/a, indicating that in the east of China＇s seas there is a sink of CO_2 to the atmosphere. The partial pressure of carbon dioxide in sea water in the east of China＇s seas has an increasing rate of 1.15 μatm/a（1μtm/a=0.101 325Pa）, but p H in sea water has an opposite tendency, which decreases with a rate of 0.001 3 a^（–1） from 1982 to 2005.Biological activity is a dominant factor that controls the pCO_2 air in the east of China＇s seas, and followed by a temperature. The inverse relationship between the interannual variability of air-sea CO_2 flux averaged from the domain area and Ni？o3 SST Index indicates that the carbon cycle in the east of China＇s seas has a high correlation with El Ni？o-Southern Oscillation（ENSO）.

The transformation of China＇s economic and government functions

The content of China＇s economic transformation is not single, and this article argues that it includes three parts. The first is the reform of economic system, the second is the change in the pattern of economic growth, and the third is the adjustment of economic structure. Government is the leading force of China＇s economic transformation, and repeated reform of government institutions has brought about some changes to government functions. But problems are obvious that lag changes of government functions have become an obstacle in China＇s economic transformation. This article describes the historical evolution and the reality of China＇s economic transformation, and analyzes the main reasons of lag changes in government functions, and reveals that the transformation of government functions is the key for successful transformation of China＇s economy.

The volume of e-commerce trade is surging, mobile payment is taking over the world, and the sharing economy is a worldwide phenomenon. In recent years, China has made remarkable achievements in the digital economy domain, which has garnered attention from a wide range of sources.

Reducing unemployment in China's economy

China’s great transformation,launched three decades ago,has changed the fate of hundreds of millions of people,including Liu Wei,an "educated youth" at the time. After having witnessed the seeming insignificance and helplessness of individuals in the face of grand social movements over the past 30 years,Liu,now an economist,shifted his attention to how the fate of ordinary people changes amid the rising and ebbing tides of the economy. While people fret over the future national well-being during complicated policy changes,Liu pointed out that employment holds key to China’s economy because employment has a direct bearing on people’s livelihood.
