The value of sharing economy in GDP data

Some people argue that the purpose of the Chinese statisticians trying to include sharing economy in the Chinese GDP data is to increase the figure and create some market confidence. This could be true, but is meaningful. We cannot deny the positive effect of sharing business in any economy that sharing business creates a way to relocate the spare and piecemeal resources efficiently. The problem here is we do not need to give values to services that are free in order to add a value to the GDP data. The true value of sharing business is to create more opportunities for double coincidences of wants in order to create more trades of goods, services, time and other resources. These trades have their values; however, as these trades are too diversified in terms of location, parties to be calculated effectively, the government usually does not have figures of the values of these trades. Moreover, some of these trades do not have official records, which makes the government even more difficult to calculate the value created by sharing business. Of course, the government can estimate the value created by sharing business and add this figure to the GDP, but such method has its weakness as it is not very convincing and may double calculate some values that are already included in the GDP data. Therefore, in order to find out a reliable and convincing GDP data, the best way is to create some data collection method to collect the data of the previously omitted trades and add the sum to the GDP data.
