To clarify the future competition strategy and selection of innovation of resource enterprises, this paper selects Shanghai and Shenzhen A Share listed resource companies in 2011—2014 as samples to establish a mediating role model based on competition strategy theory and technical innovation theory, which is applied to check the influence of different competition strategies on performance by means of Stata12.0 software, and to study the mechanism of technical innovation in competition strategy’s influence on performance. Performance of resource companies can be directly raised from low-cost strategy, and indirectly from mediating role of technical innovation as well, but only indirectly through mediating role of product innovation for differentiated strategy. It concludes that selection and conduction of competition strategy of resource enterprises should be combined with technical innovation, the both are of equal importance to sustainable development of resource enterprises.
