In 2019，Chinese NEV industry encountered multiple problems such as declining consumption，policy decline，insufficient product competitiveness，unsound using environment etc. The nearly 10-year high-speed growth in the industry was shifted into the phase of temporary restructuring. Regarding the OEMs，traditional Chinese OEMs met their Waterloo，and the annual sales volume was far below the expectation. Emerging EV makers fell into financial predicament but multinational EV makers represented by Tesla realized explosive growth. In terms of technology，indicators like vehicle energy consumption，battery power density，range kept increasing，and intelligent technologies were applied more widely. On the whole，Chinese NEV industry started early，featured large scale and acquired preemptive advantages in fields like industrial layout of key components，integrated vehicle development，public domain promotion and so on. However，the overall industrial competitiveness still lagged behind the development countries like USA and Japan. Under the influence of multiple factors such as Sino-American trade friction，COVID-19，anti-globalization，the NEV industry is experiencing the reshuffle. The book advises OEMs should grasp the situation in the new stage of NEV development，fully utilize the mode of internet + technology and eventually realize the transforming of production，sales and service.
