Enterprise Value Valuation-BYD as an Example Based on SWOT Model and Multiple Regression Model

BYD is one of the largest new energy vehicle companies in China.Analyzing its scenario and the factors that affect its value helps to understand and identify development opportunities and potential problems.On one hand,this paper makes a qualitative analysis of BYD,using SWOT model to study the internal capability and external environment of BYD.On the other hand,the multiple regression model is used for quantitative analysis of BYD’s enterprise value,and the model is established based on three factors:enterprise fundamentals,investor behavior and psychology,and macroeconomic policy uncertainty,and the stepwise regression is carried out.The results show that the increase of institutional investors’shareholding ratio,the increase of investor sentiment index,and the increase of M2 growth rate will increase the overall enterprise value,while the increase of economic policy uncertainty will decrease the enterprise value.

Impact of macroeconomic policy uncertainty on opportunistic insider trading

The macroeconomic policy environment affects the internal governance of microenterprises,which may provide opportunities for management to benefit from stock sales while decreasing its motivation to manipulate stock transactions.Using a sample of Chinese A-share listed companies from 2007 to2018,we study the impact of macroeconomic policy uncertainty on opportunistic insider trading.The results show that macroeconomic policy uncertainty helps restrain the opportunistic trading of shares held by management.When macroeconomic policies are uncertain,enterprises improve their internal governance.Furthermore,strengthening equity governance helps reduce management’s opportunistic use of the uncertainty of the policy environment,highlighting the advantageous effect of macroeconomic policy uncertainty and helping regulators standardize managerial behavior and promote the governance effect of macroeconomic policy.

Haste Makes Waste： Policy Options Facing China after Reaching the Lewis Turning Point

This paper provides a framework for assessing the health of China＇s macro economy and the sustainability of economic growth by combining supply-side and demand-side factors and by considering their relationship at different stages of development. As the Chinese economy passed through its Lewis turning point, weakened supply-side factors caused its growth to slow. The increasing concern regarding the economic slowdown has induced both the central and local governments to implement various stimulus plans through instruments of macroeconomic, industrial and regional policies. By examining where the imbalances of the Chinese economy really lie and investigating the determinants of the current slowdown and of the enhancement of the potential growth rate, the present paper suggests that the best path of action for the Chinese Government is not to stimulate growth through demand-side factors but to increase the potential growth rate through reforms in certain key areas.
