China's low-carbon transition for addressing climate change

This study discusses high-carbon characteristics, the unsustainability of China's development, and the fact that China needs to transform its development mode. China's low-carbon transition must include industry structure adjustment, energy saving and efficiency increases, energy structure improvement, carbon sink development, adaptation capability, and low-carbon pilot schemes.Low-carbon urbanization is a key measure in China's low-carbon transition. China's urbanization faces high-carbon risks. Thus, this study presents a roadmap for transforming urbanization into a low-carbon one. The transition to low-carbon urbanization is a common trend in the developing world. There is a lot of room for international cooperation.

Quantitative analysis on the contribution of industrial structure change to sustainable development: a case study of Fujian Province

Development and sustainability are the core connotation of sustainable development. Sustainability of economic development and the provision capability of resources and environment are two aspects of sustainable development. The former ones are the foundation of the latter ones. Industrial structure has a close relationship with sustainable development. The optimization of industrial structure is the important base for the sustainable development of modern economy and also the important ways of the sustainable utilization of resources and environment. The intensive growth effect of industrial structure change has the meaning of sustainable development. This paper reviews and explains the theory on the contribution of industrial structure change to sustainable development, builds the calculation model through introducing the coeff icient of industrial structure change, makes an empirical study on the contribution of industrial structure change to sustainable development in Fujian, and puts forward ways and policies of optimizing industrial structure both among industries and inside the industry in the process of industrial structure change.

Changes of Mobile Internet Ecosystem Structure and Suggestions for Regulatory Policy

The mobile Intemet industry has exp- erienced dramatic changes as plenty of new applications and business models emerged. This study conducts a qualitative review on the changes through adopting business ecosystem approaches. An analytical framework is estab- lished for reviewing the structure of mobile Internet business ecosystem. Then the core value, key actors, and inter-firm relationships of the mobile Internet ecosystem in the past and in the present are compared. It is found that the ecosystem structure has shifted from an MNO-centric model to a polycentric one with highly expanded value sources and di- versified keystone players. Accordingly some suggestions for regulatory policy makers are provided in terms of the roles of mobile Inter- net in social welfare improvement, the call for a convergent regulatory system, and chal- lenges for information security regulation.

How Skill-Biased Technical Change Sustains China＇s Comparative Advantage

The sustaining trade surplus in China has arrested more and more attentions and concerns. The industrial structure upgrading and wage rise should have kept down the trend of comparative advantage and surplus growth, but unfortunately in vain. This paper presents a theoretical framework, which is explaining the reason from SBTC induced along by FDI. In the short run, taking some outsourcing linkage home will increase the skill demand, while in the long term, skill supply will increase since the wage rise will incentive the edge skill labour, and therefore, the skill premium increase will be suppressed, comparative advantage and trade surplus sustained.

Expansion Strategies and Evolution Paths of Hotel Groups in China

The organizational structure change of enterprises should be subject to the change of strategy,and strategy change is the reaction to the environment change.This paper studied the expansion strategies and evolution paths of hotel groups in China by a survey in 2007,in which the research objects were 91 hotel groups listed by China Tourist Hotels Association.The conclusions are drawn:based on the two dimensions of unification management function scope and the unification management degree,hotel groups can be divided into four strategic types,including strategically concentrated group,close function group,widespread alliance group and loose union group.Simultaneously there are three different expansion paths:stability path,growth path and undulation path.About 72.5% of Chinese hotel groups have a stability or growth expansion path.

Offshore Wind-Parks and Northern Europe＇s Mild Winters： Contribution from Ships, Fishery, et cetera？

The marine environment of North Sea and Baltic is one of the most heavily strained by numerous human activities. Simultaneously water and air temperatures increase more than elsewhere in Europe and globally, which cannot be explained with ＂global warming＂. The climatic change issue would be better understood if this extraordinary regional warming is sufficiently explained. The regional features are unique for in-depth studies due to different summer-winter conditions, shallowness of the seas, geographical structure, and main pathway for maritime weather patterns moving eastwards. The impact of sea activities on the seasonal sea water profile structure is contributing to stronger regional warming, change in growing season, and less severe sea ice conditions. The impact of the man, whether small or large, should be understood very soon and very thoroughly.

Is There Hysteresis in Unemployment in OECD Countries？ Evidence From Panel Unit Root Test With Structural Breaks

This study tests the hysteresis hypothesis of unemployment in fifteen OECD countries by using panel unit root tests which allow for structural breaks. We apply annual unemployment rates covering 1985-2008 periods. We test whether unemployment rates are stationary by using second generation tests which allow cross section dependency among series and panel unit root test based on structural break advanced by Carrion-i-Silvestre, Barrio-Castro and Lopez-Bazo （2005）. We find series as a stationary process with structural breaks according to Carrion-i Silvestre et al. （2005） test, while we find series as unit root process with second generation panel unit root test. According to the Carrion-i Silvestre et al. （2005） test, we find the evidence of absence of hysteresis in analyzed countries. As a result, temporary shocks have temporary effects on unemployment instead of permanent effect. Structural factors can affect the natural rate of unemployment and, therefore, unemployment would be stationary around a process that is subject to structural breaks. So, there still exists a unique natural rate of unemployment to which the economy eventually will converge.

Design and control of a p-xylene oxidation process

The p-xylene(PX) oxidation process is of great industrial importance because of the strong demand of the global polyester fiber.A steady-state model of the PX oxidation has been studied by many researchers.In our previous work,a novel industrial p-xylene oxidation reactor model using the free radical mechanism based kinetics has been developed.However,the disturbances such as production rate change,feed composition variability and reactor temperature changes widely exist in the industry process.In this paper,dynamic simulation of the PX oxidation reactor was designed by Aspen Dynamics and used to develop an effective plantwide control structure,which was capable of effectively handling the disturbances in the load and the temperature of the reactor.Step responses of the control structure to the disturbances were shown and served as the foundation of the smooth operation and advanced control strategy of this process in our future work.
