Abstract Investigating the indirect tax burden of residents is an important way of understanding the effect of tax on income distribution and the tax burden transfer. In this paper, a long term MRIO model is constructed by using the regional input-output tables in China. We simulate the flow of value-added tax, consumption tax and business tax in different departments of 30 provinces (except Tibet) in mainland China from the perspective of rows in the IO table, we obtain the real burden of three indirect taxes on urban residents, and discuss the transfer of tax burden among regions. The conclusions are as follows: There are large differences in tax burden among regions. The real tax burden shifted from the eastern region to the middle and the western regions. Indirect tax aggravates the income inequality of urban residents in different regions. The indirect tax in China has a certain degree of regression. Based on the empirical analysis, we think the government should make the following policy changes: 1) Giving more consideration to the consumption terminals; 2) Adjusting preferential policies of regional taxation; 3) Increasing the amount of preferential policies for the western region.

Abstract The empirical investigation that examines the dynamics including the interaction between consumption of energy and economic progress has long been assessed. However, the interaction of these two in developing countries in general and Bangladesh, in particular, is a less explored subject. Hence, with this notion, this study examined the causal relationship among economic growth and energy consumption in Bangladesh. For this purpose, the study used energy consumption, gross domestic product (GDP), labor force, and capital data from 1981 to 2017 from different sources and data is analyzed by augmented Dickey-Fuller (ADF) unit root test, Johansen co-integration test and Granger test of causality. Results determine that energy consumption and economic growth have long term bi-directional relationship. The econometric model is estimated using generalized least squares (GLS) model. It is concluded that, consumption of energy and economic growth positively correlated and economic development highly depend on energy consumption in Bangladesh.

Abstract In order to analyze the impact of technological innovation and regional differences in marine economy on the development of marine economy, the paper uses the regional panel data of China’s total marine production value from 2006 to 2015, and uses the Theil index to measure regional differences in the marine economy based on the logarithm of the Cobb-Douglas production function. Finally, the paper establishes a random effect panel data model for empirical analysis. The research indicates that the regional differences in the marine economy show a narrowing trend, which promotes or inhibits the development of the marine economy; The extent of the impact of regional differences in the marine economy on the development of the marine economy is inconsistent; Scientific and technological innovation in various regions has promoted the development of marine economy.

Abstract In grey models, GM(1, 1) is an important prediction model. The grey model GM(1, 1) has good prediction results in the case original data change exponentially at a low speed. However in practical cases sometimes, original data show exponential changes or approximately exponential changes change at a high speed. In these cases, the grey model GM(1, 1) has poor prediction results because the data fail to meet the laws of traditional model. Therefore, the paper proposes an extended grey model GM(1, 1, ebk) and its modeling method. In the final section, the paper builds grey models of GM(1, 1, ebk) for a practical problem and the results show the grey model proposed has greatly improved simulation and prediction accuracy compared with the traditional model.

Abstract This paper attempts to evaluate the coordinated development state of the subsystems within the internet financial ecosystem in China from 2011 to 2016. Focusing on the main business modes, technological innovation, and the external environment, we select 29 indicators to construct an index system and adopt a coupling coordination degree model for evaluation. Furthermore, we use two weight calculation methods, entropy weight and principal component analysis, to ensure the robustness of the results. The empirical results show that China’s internet financial ecosystem experienced five development stages from 2011 to 2016, which are moderate disorder, near disorder, weak coordination, intermediate coordination, and good coordination. Different methods of obtaining weights have little effect on the empirical results. These findings suggest that at the beginning, the coordinated development of China’s internet financial ecosystem was hindered by factors including the scarcity of main business modes and the defect of technological innovation; then, with the rapid development of China’s internet industry, the external environment became another drawback in coordinated development. Finally, based on the findings, we give some policy recommendations from a global perspective to achieve a sustainable internet financial ecosystem.

Abstract We used the basic principles of game theory to investigate development strategies for standards of professional competence in universities in the same geographic area, under conditions of non-uniform distribution of social demand preference. The results revealed that, under various conditions in our model, different approaches for differential strategies were selected by university U2 compared with university U1. Specifically, in the competition between U1 and U2, there is a differential strategy compression point of U2 to U1; When U2 universities choose the biggest differentiation strategy, university U1 also have differentiated strategy control points. Arbitrary decision-making of university U1 in relation to university U2 was based on the requirements of professional competence standards, according to the change of the social demand for professional competency standard, universities U2 will adopt the strategy of “no difference”, “maximum differentiation” and “comprehensive intermediate strategy”, respectively. The current results have theoretical implications for the selection of professional development and professional competence development strategies in asymmetric universities operating in the same geographic area.

Abstract In this paper, the optimal tracking control problem for discrete-time with state and input delays is studied based on the preview control method. First, a transformation is introduced. Thus, the system is transformed into a non-delayed system and the tracking problem of the time-delay system is transformed into the regulation problem of a non-delayed system via processing of the reference signal. Then, by applying the preview control theory, an augmented system for the non-delayed system is derived, and a controller with preview function is designed, assuming that the reference signal is previewable. Finally, the optimal control law of the augmented error system and the optimal control law of the original system are obtained by letting the preview length of the reference signal go to zero.

Abstract Using Cobb-Douglas production function with increasing returns to scale, this paper presents an intra-industry trade model which contains two factors, capital and labor. Thus, this paper extends Krugman’s (1980) single-factor model to a two-factor model with the entry cost. Firstly, an equilibrium analysis of closed economy is carried out. After the condition of existence and uniqueness of equilibrium is obtained, the analytic solutions are given. Secondly, it provides an analysis on trade effects. The results show that, under setup of symmetry among firms, the intra-industry trade can only enable consumers to benefit from product diversification without making firms achieve economies of scale. Obviously, this conclusion is consistent with Krugman (1980), which thus indicates robustness of Krugman’s (1980) model.

Abstract Information flow retains a critical role in decision making among investors. In this paper, we employ a diffusion model based on epidemiology theory to study the rumor spreading process within investors. The paper introduce the feedback mechanism of classical control theory into the model, which helps to reflect the interaction between rumor spreaders and information supervision. Further we apply a time delay factor to give investors access to transparent information and change their behavior. Subsequently, the stability of the rumor disappearance equilibrium and the rumor existence equilibrium are analyzed and the condition for the system undergoes a Hopf-bifurcation is given. The mathematical arguments are subjected to numerical simulations to present the ideal case scenarios. The results suggest that, increase the general strength of information supervision and the proportion coefficient associated with the infected population in the short-term delay are conducive to better control.
