Research on Tangibility of CNPC Technology ZhangYundong and Zhang Li 2014, 33(1): 1-5.  Abstract ( )   PDF (5252KB) ( )   In the past decades, China National Petroleum Corporation (CNPC) has developed a series of mature, advanced and applicable technology, but most of the technology fails to find wide application and is commercialized at a low level thanks to its low integration, low domination and low intangibility. With implementation of the strategy to build CNPC into integrated international energy company, it is of great urgency for CNPC to make its accumulated intangible technology dominant and tangible in order to develop, share, industrialize and commercialize the technological assets for a large-scale application, boosting the company’s core competitiveness. CNPC is making efforts for collection and classification of its unique technology to meet the technological demand for the company’s business development both at home and abroad. Based on the principles of “making an all-around design, highlighting the characteristics, identifying the carrier, establishing the assets, sharing for development and focusing on application,” CNPC is making the efforts for tangibility of technology. Remarkable results have been achieved in expansion of technological application through tangible integration, bringing about technological and commercial values of technological results.
