我国地区R&D资本存量测算:1978—2015年

The Measurement of China's Regional R&D Capital Stock: 1978—2015

2008年国民账户体系(SNA)拓展了固定资产的边界,研发(R&D)被视为一类新的固定资产,列入了知识产权产品。目前,官方统计并未给出我国各地区的R&D资本存量数据,现有文献也鲜有讨论2008年SNA框架下的相关测算。因此,本文依据2008年SNA和现有的统计资料,在合理估计1978年以来各地区的当期R&D投资的基础上,采用永续盘存法科学测算了1978—2015年各地区的R&D资本存量数据。结果显示:1978年以来,我国各地区R&D资本存量总体上呈快速上升趋势;各地区R&D资本存量年均增速与各地区GDP年均增速具有正相关关系;我国的R&D资本存量主要由东部地区贡献,东部地区是我国研发创新的主要区域。

2008 System of National Accounts （SNA） expands the boundaries of fixed assets, and Research and Development （R＆D） is regarded as a new class of fixed assets, which is included in intellectual property products. At present, the official statistics has not given the regional R＆D capital stock data in China, and the existing literatures also have rarely discussed the relevant estimates under the framework of 2008 SNA. Therefore, based on the 2008 SNA and existing statistics, this paper estimates the current R＆D investment reasonably in each region since 1978, and then calculates the regional R＆D capital stock scientifically from 1978 to 2015 with perpetual inventory method. The results show that, R＆D capital stock in all regions increase rapidly overall since 1978 in China; the average annual growth rate of regional R＆D capital stock is positively related to the average annual growth rate of GDP. In China, R＆D capital stock is mainly contributed by the eastern regions, and the eastern regions are main innovation fields.
