Can Information Disclosure Technology Improve Investment Efficiency? — Empirical Evidence from China

We study the impact of adopting a new financial reporting technology, XBRL (eXtensible Business Reporting Language) on firms' investment efficiency in the Chinese market. Our primary finding is that adoption of XBRL is associated with improvement in investment efficiency. Specifically, XBRL implementation significantly curbs both under-and over-investment for all listed Chinese firms and the impact on over-investment is 6 to 9 times larger than that on under-investment. This negative association of XBRL adoption and investment inefficiencies is robust conditional on firms' financial constraints as well as whether a firm is SOE (state-owned-enterprise), both of which affect a firm's availability of capital and thus investment efficiency
