Abstract: Information is the basis for making investment decisions, and the attitude of decision makers towards the media is also an important factor affecting investment decisions. This article uses data from the 11th Chinese Private Enterprise Survey conducted in 2014 to examine the relationship between business owners' trust in official media and corporate investment decisions. The study found that: (1) Trust the official media can expand the overall investment of the enterprise, but it mainly promotes long-term investment. This conclusion is still true after dealing with endogenous issues and conducting a series of robustness tests; (2) In terms with mechanism, trust the official media can reduce entrepreneurs' perception of environmental risks and improve their own status, thus creating psychological conditions for entrepreneurs to making positive investment decisions. This study shows that strengthening private entrepreneurs' trust on official media is an effective way to incentivize corporate investment. Therefore, the role of official media on disseminating policy information should be further strengthened to alleviate information asymmetry caused by non-market factors and create a favorable information environment for private enterprises to expanding private enterprise investment.
