A Study on the Dynamic Relationship between Cultural Industry and Economic Growth
Yugang He 한국유통과학회 2018 한국유통과학회 학술대회 논문집 Vol.2018 No.-
This paper attempts to explore the dynamic relationship between cultural industry and economic growth. On the grounds of Cobb-Douglas production function, the cultural industry is regarded as a determinant to impact economic growth. Meanwhile, the quarterly datum form the first quarter of 2000 to the fourth quarter of 2017 are employed to conduct an empirical analysis under the vector error correction model. Furthermore, a menu of statistic approaches will be used to testify the dynamic relationship between cultural industry and economic growth. Via the Johansen co-integration test, the results report that the cultural industry has a positive effect on economic growth. Through the vector error correction estimation, the results also report that the cultural industry also has a positive effect on economic growth, but less than that of the Johansen co-integration test.
Sliding Mode Control for a Class of Nonlinear Ito Stochastic Systems with State and Input Delays
Yugang Niu,Bei Chen,Xingyu Wang 제어·로봇·시스템학회 2009 International Journal of Control, Automation, and Vol.7 No.3
This paper deals with the problem of sliding mode control (SMC) for a class of nonlinear stochastic systems. The nonlinear uncertainties are unknown and unmatched. There exist state and input delays. A special switching function is designed such that the insensitivity of the system can be guaranteed throughout the entire response of the system from the initial time instance. Both the sliding surface and the sliding mode controller exist if a set of matrix inequalities is feasible. A simulation example is given to illustrate the proposed method.
Does Individual's Income always Matter Happiness?: Evidence from China
Yugang HE,Renhong WU 국제융합경영학회 2020 웰빙융합연구 Vol.3 No.1
As people's income rises dramatically, people's happiness seems not as high as expected. In fact, there are two different arguments about the relationship between income level and happiness. The focus of the debate is whether the correlation between income and probability of happiness is positive or negative. Therefore, we hypothesizes that the relationship between income and probability of happiness presents an inverted U-shaped curve. Then, this paper sets China as an example to explore the effect of income on happiness. The data from the Chinese General Social Survey (CGSS) in 2015 is employed to conduct empirical analyses under the Probit model and the Zero-Inflation-Passion model. The empirical findings indicate that the effect of income on happiness presents an inverted U-shaped curve and significantly in statistic. Meanwhile, spouse’s income, educational level, marriage time and house property have a positive and significant effect on happiness.Conversely, age and local living standards have a negative and significant effect on happiness. Unfortunately, even though registered residence and children have a negative effect on happiness, they do not get through the significant test. In order to ensure the robustness of our empirical results, we test the robustness of the above empirical results by adjusting the sample size. The results of robustness test verify that our empirical results are robust. Moreover, this paper also makes a small contribution to the current literature with a sample from China.

This paper addresses dynamic modeling and task-space trajectory following issues for nonholonornic mobile manipulators moving on a slope. An integrated dynamic modeling method is proposed considering nonholonomic constraints and interactive motions. An adaptive neural-fuzzy controller is presented for end-effector trajectory following, which does not rely on precise apriori knowledge of dynamic parameters and can suppress bounded external disturbances. Effectiveness of the proposed algorithm is verified through simulations.

This paper contributes to the present research stream by exploring the effect of China’s OFDI over the period 2003-2019 in the case of Korean peninsula. On account of the auto-regressive distributed lag model and Granger causality approach of vector error correction, an inference is drawn that China’s OFDI significantly contributes to the economic growth in Korean peninsula whenever in the short run and long run. However, this kind of contribution is asymmetric in which the contribution of China’s OFDI to North Korea’s economic growth is greater than that of South Korea. Moreover, the long-run causality results originate the bi-directional causality between China’s OFDI and economic growth in Korean peninsula.
A Panel Analysis on the Cross Border E-commerce Trade: Evidence from ASEAN Countries
Yugang He,Jingnan WANG 한국유통과학회 2019 The Journal of Asian Finance, Economics and Busine Vol.6 No.2
Along with the economic globalization and network generalization, this provides a good opportunity to the development of cross-border ecommerce trade. Based on this background, this paper sets ASEAN countries as an example to exploit the determinants of cross-border ecommerce trade including the export and the import, respectively. The panel data from the year of 1998 to 2016 will be employed to estimate the relationship between cross-border e-commerce trade and relevant variables under the dynamic ordinary least squares and the error correction model. The findings of this paper show that there is a long-run relationship between cross-border e-commerce trade and relevant variables. Generally speaking, the GDP(+) and real exchange rate(-export & +import) have an effect on cross-border e-commerce trade. However, the population (+) and the terms of trade (-) only have an effect on cross-border e-commerce import. The empirical evidences show that the GDP and the real exchange rate always affect the development of cross-border e-commerce trade. Therefore, all ASEAN countries should try their best to develop the economic growth and focus on the exchange rate regime so as to meet the need of crossborder e-commerce trade development.
A Study on the Balassa-Samuelson Hypothesis: Evidence from China
Yugang He,최용재 한국아시아학회 2018 아시아연구 Vol.21 No.1
This paper focuses on the linkage among relative labor productivity, real exchange rate and foreign exchange reserve of China as well as the relative labor productivity of U.S. under the Balassa-Samuelson Hypothesis. This paper applies quarterly data from 2000 to 2016. An empirical analysis is conducted using the vector error correction model (VECM). The empirical analysis results show that the Balassa-Samuelson Hypothesis is significant in China in the long run. To be specific, an increase in relative labor productivity (the ratio of the manufacturing industry to the tertiary industry) will result in RMB appreciation. An increase in the relative labor productivity of U.S. (the ratio of the manufacturing industry to the non-farm business sector) will lead to the RMB depreciation. An increase in the foreign exchange reserve (a replacement of the reserve asset) will bring about RMB appreciation.

Purpose - From the advanced path of development and current situation, the development of enterprises plays a tremendous role in promoting national economic growth and raising the overall national strength. Therefore, this paper aims at examining the mutual effect between small & medium enterprises and economic growth. Research design, data, and methodology - In order to address the operating mutual effect between the small & medium enterprises and economic growth more clearly, this paper sets Alibaba Group and Hangzhou as an example. Meanwhile, the annual data from 2000 to 2017 will be employed, and an empirical analysis will be performed under the vector error correction model. Results - The findings display that the total revenue of Alibaba Group has a positive effect on economic growth in city of Hangzhou. However, the Granger Causality test implies that there is only a unidirectional causality between total revenue of Alibaba Group and economic growth in Hangzhou. More specifically, 1% increase in total revenue of Alibaba Group can result in 0.272% in economic growth of Hangzhou in the long run. Conclusions - In summary, for the long run, the local governments should promulgate a series of policies to assist the small & medium enterprises like Alibaba Group to improve the local economic growth as seen in the city of Hangzhou.
H∞ Control for Networked Systems with Data Packet Dropout
Yugang Niu,Tinggang Jia,Xingyu Wang 제어·로봇·시스템학회 2010 International Journal of Control, Automation, and Vol.8 No.2
This paper considers the control problem of networked control systems, respectively, for the two cases that system state is available and unavailable. It is assumed that there exists a communication network in the feedback loop, and multiple data packet dropouts may happen. An estimation method is introduced to compensate the lost data. And then, the design of control is considered for the states available and states unavailable, respectively, and some sufficient conditions are derived such that the closed-loop systems are exponentially mean-square stable with prescribed disturbance attenuation level.
