Nonlinear Effects of Fiscal Policy on Private Consumption:Evidence from China

引用

China & World Economy 2011年第2期19卷 60-76页

作者： liyong wang Wei Gao Associate Professor School of Economics Central University of Finance and Economics Beijing China. Email: liyong_wang@*** Associate Professor School of Economics Central University of Finance and Economics Beijing China. Email: yf0201@***.

In the present paper, we use the Markov-switching model to test the nonlinear effects of government expenditure and taxes on private consumption in China. The results show that fiscal policy in China has a significantly nonlinear effect. In years 1978-1980 and 1984- 1997, the effect of government consumption on private consumption is non-Keynesian. During the same periods, the effect of taxes is also non-Keynesian, but the effect is not significant. The effect of government investment is linear but asymmetric. After retesting the reasons for the existence of nonlinear effects, we find that in China initial fiscal conditions and the magnitude of fiscal consolidations are not related to the nonlinear effects of fiscal policy. The government should pay close attention to the characteristics of commodity and labor markets to identify the conditions and regimes associated with nonlinear effects.

引用

Chemical Research in Chinese Universities 2013年第3期29卷 466-472页

作者： LIU Zhuo PAN Li liyong-hong wang Su-hua LI Zheng-ming State Key Laboratory of Elemento-Organic Chemistry Institute of Elemento-Organic Chemistry Nankai University Tianjin 300071 P. R. China

A series of new sulfonylureas incorporating 1,2,4-triazolinone moiety was synthesized, which were further bio-assayed for the herbicidal activity against four herbs, representative of monocotyledons and dicotyledons. Some of them exhibited high potency to inhibit the growth of dicotyledons（Bassica napus and Arnaranthus retroflexus） in the pot experiment. Compounds 9a and 9b also displayed an excellent herbicidal activity against Bassica napus at a concentration of 15 g/hectare, which were comparable with commercial triasulfuron.

Downregulation of nc886 contributes to prostate cancer cell invasion and TGFβ1-induced EMT

引用

Genes & Diseases 2022年第4期9卷 1086-1098页

作者： Ronghui Yang Lingkun Zuo Hui Ma Ying Zhou Ping Zhou liyong wang Miao wang Mahrukh Latif Lu Kong Department of Biochemistry and Molecular Biology Capital Medical UniversityBeijing 100069PR China Biomedical Engineering Institute of Capital Medical University Capital Medical UniversityBeijing 100069PR China Department of Pathology Beijing Friendship HospitalThe Second Clinical Medical College of Capital Medical UniversityBeijing 100050PR China Department of Nuclear Medicine Fourth Hospital of Hebei Medical UniversityShijiazhuangHebei 050010PR China

Epithelial-to-mesenchymal transition (EMT) activation is important in cancer progression and metastasis. Evidence indicates that nc886 is a representative Pol III gene that processes microRNA products via Dicer and further downregulates its target gene transforming growth factor- β1 (TGF-β1), which is the most prominent inducer of EMT in prostate cancer (PC). Consistent with the previous literature, we found that nc886 downregulation was strongly associated with metastatic behavior and showed worse outcomes in PC patients. However, little is known about the association between nc886 and the EMT signaling pathway. We developed a PC cell model with stable overexpression of nc886 and found that nc886 changed cellular morphology and drove MET. The underlying mechanism may be related to its promotion of SNAIL protein degradation via ubiquitination, but not to its neighboring genes, TGFβ-induced protein (TGFBI) and SMAD5, which are Pol II-transcribed. TGF-β1 also override nc886 promotion of MET via transient suppression the transcription of nc886, promotion of TGFBI or increase in SMAD5 phosphorylation. Both nc886 inhibition and TGFBI activation occur regardless of their methylation status. The literature suggests that MYC inhibition by TGF-β1 is attributed to nc886 downregulation. We incidentally identified MYC-associated zinc finger protein (MAZ) as a suppressive transcription factor of TGFBI, which is controlled by TGF-β1. We elucidate a new mechanism of TGF-β1 differential control of Pol II and the transcription of its neighboring Pol III gene and identify a new EMT unit consisting of nc886 and its neighboring genes.

Influence of Converter Bus Serious Harmonic Distortion on HVDC Transmission System

自动化学报 2017年第8期43卷 1412-1417页

作者： Ziyu Guo Tao Lin Gengtao Jia liyong wang Solar Energy Efficient Use Collaborative Innovation Center School of Electrical Engineering Wuhan University Wuhan 430072China State Grid Shanghai Information and Telecommunica-tion Company Shanghai 200010 China State Grid Beijing Electric Power Company Beijing 100031 China

Possibility of serious harmonic distortion (SHD) increases as multi-infeed direct current (MIDC) transmission develops rapidly in recent years. In this paper, the mechanism of high voltage direct current (HVDC) controller working against SHD is proposed for theoretical derivation of phase locked loop (PLL) output and valve commutation process. To reduce static error of constant extinction angle (CEA) controller and enhance active power transmission, the insertion of current error (CE) controller into CEA is minified. A calculation of inverter operating point is proposed in the end. The correctness of mechanism and algorithm is verified through power systems computer aided design (PSCAD) simulation.

Short-Term Household Load Forecasting Based on Attention Mechanism and CNN-ICPSO-LSTM

引用

Energy Engineering 2024年第6期121卷 1473-1493页

作者： Lin Ma liyong wang Shuang Zeng Yutong Zhao Chang Liu Heng Zhang Qiong Wu Hongbo Ren New Energy Technology Center State Grid Beijing Electric Power Research InstituteBeijing100075China College of Energy and Mechanical Engineering Shanghai University of Electric PowerShanghai200090China

Accurate load forecasting forms a crucial foundation for implementing household demand response plans andoptimizing load scheduling. When dealing with short-term load data characterized by substantial fluctuations,a single prediction model is hard to capture temporal features effectively, resulting in diminished predictionaccuracy. In this study, a hybrid deep learning framework that integrates attention mechanism, convolution neuralnetwork (CNN), improved chaotic particle swarm optimization (ICPSO), and long short-term memory (LSTM), isproposed for short-term household load forecasting. Firstly, the CNN model is employed to extract features fromthe original data, enhancing the quality of data features. Subsequently, the moving average method is used for datapreprocessing, followed by the application of the LSTM network to predict the processed data. Moreover, the ICPSOalgorithm is introduced to optimize the parameters of LSTM, aimed at boosting the model’s running speed andaccuracy. Finally, the attention mechanism is employed to optimize the output value of LSTM, effectively addressinginformation loss in LSTM induced by lengthy sequences and further elevating prediction accuracy. According tothe numerical analysis, the accuracy and effectiveness of the proposed hybrid model have been verified. It canexplore data features adeptly, achieving superior prediction accuracy compared to other forecasting methods forthe household load exhibiting significant fluctuations across different seasons.
