打假——“3C”认证面临的“老问题”

假冒伪劣,是伴随着改革开放,经济发展的深入而出现的经济现象,由此产生的打假工作也进行了近20年。但可以肯定的是,假冒伪劣现象并不会因为国家强力推出的强制性产品认证而立刻消失,相反,由于质检的对象的增加,打假的工作任务可能更加艰巨。3C认证是一个契机,一个掀起群众性打假运动的良好开端。在做好打假管理部门的职能转变、强化市场秩序的整治、规范外,我们还应从引导企业做强做大、加强企业知识产权意识和端正地方领导经济发展指导思想等方面着手,以期假冒伪劣问题的更快、更彻底的解决。

Non-classical Algorithm for Time Series Prediction of the Range of Economic Phenomena With Regard to the Interaction of Financial Market Indicators

The aim of the article is to present non-clasical copyrighted algorithm for prediction of time series, presenting macroeconomic indicators and stock market indices. The algorithm is based on artificial neural networks and multi-resolution analysis （the algorithm is based on Daubechies wavelet）. However, the main feature of the algorithm, which gives a good quality of the forecasts, is all included in the series analysis division into, a few partial under-series and prediction dependence on a number of other economic series. The algorithm used for the prediction, is copyrighted algorithm, labeled M.H-D in this article. Application of the algorithm was performed on a series presenting WIG 20. The forecast of WIG 20 was conditional on trading the Dow Jones, DAX, Nikkei, Hang Seng, taking into account the sliding time window. As an example application of copyrighted model, the forecast of WIG 20 for a period of two years, one year, six month was appointed. An empirical example is described. It shows that the proposed model can predict index with the scale of two years, one year, a half year and other intervals. Precision of prediction is satisfactory. An average absolute percentage error of each forecast was： 0.0099%---for two-year forecasts WIG 20; 0.0552%--for the annual forecast WIG 20; and 0.1788%---for the six-month forecasts WIG 20.

Research on the Diffusion Model of Innovation

In this paper, the model of competing technologies diffusion was set up in order to analyze the relationship of competing technologies in diffusion process, and the stability of diffusion model with two kinds of competing technologies was analyzed. It is concluded that dominator can hold competing vantage by suppressing its opponent, and besides, whether competing technology can gain superiority in diffusion process depends on the success rates of technology diffusion when the two kinds of technology match each other in strength.

Is Using Mathematics and Game Theory in Analyzing Economic Phenomena Scientific？

In the article, the author presents some arguments concerning the ＂mathematical method issue＂ in modem economics. The author shows why some reasons, according to which we should use mathematics in （economic） theory, are not convincing （they are even tautological）, and what does mathematization have to do with arbitrariness of the orthodox economic theory. The author also shows why using game theory （a mathematical discipline） in modem microeconomics does not yield knowledge and correct explanation of economic situations and phenomena. At the end, the author presents fundamental questions that form the basis of economic science and its qualitative research methods, and shows what their practical relevance is. The purpose of this article is to argue, contrary to common opinion, that there can be an exact and objective science of economic phenomena that does not necessarily use modem mathematical theories or methods to explain these phenomena.

Social Psychology in the Marketing

Marketing psychology is science which studies socio-economic phenomena, and explain the application of social market, using psychological methods and theoretical, and is in-depth community school of learning; After nearly 20 years development, Chinese marketing psychology still emphasis on Western-style research, and seems to having divorced from a hot issue of market economy in a way yet to be in efforts to be used in marketing among psychology. Through the discussion of the applications of marketing psychology, trying to appeal to all the scholars return to create the purposes of marketing psychology, like other disciplines, like out of development path of striving to become typical combined with Chinese social market economy and psychology.

An investigation on the Correlation between Unemployment and Living Conditions in Zambia： A Case Study of Kaunda Square Stage II

Most of the Zambian population, the poor people in affluent society, are enmeshed in the net of poverty. The Zambian government seems to have failed in its contractual obligation to respect and sustain its social contract with the people. There is a seemingly total collapse of social security, increased unemployment rate and consequently decreased living conditions among the youth. This study sets out to investigate the correlation between unemployment and living conditions in Kaunda Square Stage II by analyzing the impact of unemployment and suggests strategic solutions to mitigate the levels of unemployment. The primary objective of this study is to investigate the impact on the living conditions caused by unemployment in Zambia specifically in Kaunda Square Stage II and adopt strategic solutions that will mitigate creation of jobs to improve the living conditions. The study underscores that unemployment is a universal phenomenon, not necessarily a peculiar characteristic of any segment of the society. Reducing poverty, preventing excessive inequality, and generating adequate employment are the three most important goals of a macroeconomic strategy that seeks to improve the living standards of the population. Inequality and employment are each a complex phenomenon and difficult to capture with a single measurement, particularly in a low-income economy undergoing change. It is in this context that the study intends to investigate the correlation between unemployment and living conditions in Kaunda Square Stage II and to provide strategic solutions that may improve living conditions in Kaunda Square Stage II. The study concludes that high unemployment in Kaunda Square Stage II increases poverty which subsequently affects living conditions. Therefore, when, unemployment rates increase the opportunities for earning income decreases which instigate individuals to be poor. The paper closes with reflections on how good strategic solutions can be used to underwrite more employment reduction strategies.

The Influencing Factors of sCER Price Dynamics Under the Clean Development Mechanism: Theory and Econometric Analysis

In order to explore the factors and their complex mechanism affecting the price dynamics under the clean development mechanism （CDM）, this article employs the secondary Certified Emission Reduction （sCER） carbon price as the study object, and analyzes its influencing factors from aspects of the international carbon-reduction policies, macroeconomic fluctuations, energy and similar carbon products prices. The innovation of this paper lies in： Introducing necessary factor （the developing countries pricing power） and the application of several international representative indicators to un- derline the ＂world＂ nature of CDM; utilizing different econometric models to obtain noteworthy and more robust results. The authors test the theoretical findings with multiple stationary time series from the launch of CDM to present （2008-2016）. The results reveal that sCER price fluctuation shows the characteristic of asymmetry and substantial persistence. There is a strong statistically significant relationship between macroeconomic conditions, coal and oil prices, with the price of sCER. The authors discover that the pricing power of developing countries indeed has a clear but small impact on the sCER price changes, whereas the price elasticity of supply under CDM is so weak. The interaction between EU emission allowances （EUAs） and sCER presents a shift from dependency to substitution.

A SINGULAR BIOECONOMIC MODEL WITH DIFFUSION AND TIME DELAY

This paper studies a prey-predator singular bioeconomic system with time delay and diffusion, which is described by differential-algebraic equations. For this system without diffusion, there exist three bifurcation phenomena： Transcritical bifurcation, singularity induced bifurcation, and Hopf bifurcation. Compared with other biological systems described by differential equations, singularity induced bifurcation only occurs in singular system and usually links with the expansion of population. When the diffusion is present, it is shown that the positive equilibrium point loses its stability at some critical values of diffusion rate and periodic oscillations occur due to the increase of time delay. Furthermore, numerical simulations illustrate the effectiveness of results and the related biological implications are discussed.
