Abstract: Capital service is a key element for measuring total factor productivity and capital return rate. Based on international standard framework of capital services measurement, this study measures the Chinese industrial capital services by asset types and by 19 categories containing 72 sectors from 1994 to 2014, especially focusing on the information and communication technology. The results show that ○1 the measured investment series, the basic data of capital service accounting, is the key factor affecting the accuracy of capital services measurement; ○2 Investment has been an important driving force for China's economic growth. After 2006, ICT capital played a more and more important role in GDP growth; ○3Chinese ICT capital is confined to some industries such as financial intermediation, manufacturing of communication, computers, and other electronic equipment, information transmission, software and information technology, and construction. And the volume index of the ICT capital services has been declining since 2004.
