Under the innovation system integrated with production, teaching and researching, the evolution mechanism of knowledge theme becomes central point in academic fields. However, previous researches mostly focused on analyzing the tendency of academic achievements, didn’t bring the potential interaction between the production and researching into consideration. In this paper we will use the co-integration analysis and Granger causality test methods, which are prevalent in economics research, to study the evolution of specific knowledge theme – “Cloud computing”. Our main purpose is to reveal the evolution mechanism as well as general principle of popularity of one theme.

Integration Analysis

This paper empirically examines the relationship between carbon emissions and economic growth by applying the co-integration analysis and Granger causality test to the time series data of carbon emissions and gross domestic product (GDP) of the world’s top 20 emitters from 1990 to 2015. Co-integration analysis shows that there is a long-term equilibrium relationship between carbon emissions and economic growth in most countries; Granger causality test verifies a one-way causal link between carbon emissions and economic growth in most major emitters. In developed countries, economic growth is the Granger cause of carbon emissions, while the opposite is true in developing countries. The results reflect different characteristics regarding carbon emission reduction in developed and developing countries as they are at different developing stages. Carbon emission reduction exerts much greater adverse effects on the economic growth of developing countries than it does on that of developed countries. Based on the results of the Granger causal analysis, it is found that the requirements for developing countries to substantially reduce emissions are not in line with the characteristics in their current developing stage and therefore may pose obstructions. Developed countries should take the lead in carrying out emission reductions due to their accountability for historical emissions as well as their development stages and capabilities. In addition, they should aid developing countries in their efforts for transforming and upgrading development and reducing dependence of economic growth on carbon emissions. International climate governance should take into account the needs and characteristics of different countries for future development, and build a mechanism for international cooperation to achieve synergy between social economic development and global climate governance.

According to the statistics from 1980 to 2010 in Hebei province's GDP growth, as well as the total energy consumption EC statistics., the author conducted an empirical study on the relationship between economic growth and energy consumption in Hebei, using co-integration analysis, Granger causality test and error correction model. Studies have shown that it exists cointegration between economic growth and energy consumption in Hebei Province, and there was unidirectional causality from energy consumption to economic growth. that is, economic growth in Hebei Province is energy-dependent. Based on the research results, this paper gives some suggestions for economic development in Hebei Province.

Problems such as high cost of building a testing environment, low degree of automation and low rates of resource utilization are commonly met during the dispatching automation master system software testing. Cloud Computing technologies were introduced to solve these problems. Test methods based on the virtualization and other key technologies were studied and a testing platform includes user management module, testing resource management module, testing management module and man-machine interaction interface module was built. A method composed of three testing modes was presented which can be applied usefully in the static and dynamical testing of dispatching automation master system. Future research direction is prospected in the end of the paper.

Based on the data of large and medium-sized industrial enterprises put forward by National Bureau of Statistics of China, over the period 1991-2007, this paper empirically investigates the dynamic econometrical relationship among R&D, technology transfer, including imports of technology and purchase of domestic technology and innovation performance which is denoted by new product sales, using ADF unit root test, co-integration analysis and granger causality test. The empirical research results indicate that innovation performance is granger causing R&D and technology transfer, while R&D and technology transfer are not granger causing innovation performance. Neither the feedback effect between R&D and innovation performance nor that between technology transfer and innovation performance is occurring.

The Phenomenon of China Studies at the Institute of the Middle and Far East of the Jagiellonian University Modern China became the phenomenon eagerly investigated by wide circles of observers. This trend is associated with a growing number of academic fields with the Asiatic profile on the level of university education. Such characteristics is completely reflected in studies conducted at the Institute of the Middle and Far East of the Jagiellonian University. The purpose of this research is to comprehend a phenomenon of the current interest in Asia developed in Poland, with an example of China, among students of fields at the Institute with the Chinese profile. In recent years, the Institute of the Middle and Far East of the Jagiellonian University became the largest academic institution in Poland conducting this type of studies in nonphilological fields. Research proved that studies on China match the need of educating persons who both know Chinese and have specific knowledge about this country. Uniqueness of the field of study and created professional chances appeared to be equally important.
