China has revised up the size of the world's second-largest economy by adding research and development (R&D) spending into its calculations for gross domestic product, the statistics bureau said on Tuesday.
The move will help bring China's calculations for the value of its goods and services more in line with global standards set by the United Nations and other world organizations, amid widespread investor skepticism about the accuracy of the country's official data.
The new method has increased the value of GDP but has only slightly affected annual growth rates, the National Bureau of Statistics (NBS) said on its website. Growth for 2015 was amended marginally, but basically remained at 6.9 percent, the slowest in a quarter of a century.
The value of 2015 GDP was revised up by 1.3 percent to 68.55 trillion yuan ($10.3 trillion) from the previously announced 67.67 trillion yuan, the bureau said.
"Rapid growth of R&D spending and activities have played an increasingly important role in promoting economic growth, but the traditional accounting method cannot fully reflect such an impact," the bureau said.
