NSB: 2018 China National Economics and Social Development Statistics Published

April 19, 2019

Recently, the National Bureau of Statistics of China (NBS) issued the "Statistical Bulletin on National Economic and Social Development in 2018". It is noted that in 2018, the R&D expenditure in China was 1.9657 trillion yuan, an increase of 11.6% over the previous year, exceeding the average of the 15 EU countries. The number of domestic and foreign patent applications was 4.323 million, up 16.9%, and the number of patents granted was 2.447 million, up 33.3%, both of which ranked first in the world. It’s more obvious for science and technology to be “the first drive” for innovation-driven development in the country.

 

 

According to the bulletin, 55,000 PCT international patent applications were accepted by China last year; as of the end of 2018, there were 8.381 million effective patents in China, and 11.5 invention patents per 10,000 population; totally 412,000 technology contracts were signed with the turnover of 1,769.7 billion yuan, an increase of 31.8% over the previous year.
