On the left, the three lines represent the year-over-year growth of China's fixed asset investment. The orange line is for state-owned companies, which sometimes would invest based on the government's objectives. The blue line is for private businesses, and their investment decisions are more driven by their business outlook and executives' confidence on the economy.
On the right, the grey line is China's retail sales and the blue line is online sales. Retail sales are determined by the general public's income growth and confidence on their finances. China's online shopping has been a bright spot in recent years and its growth rate has been significantly above general retail spending.
