Although China’s market-oriented reform of scientific and technological system is continuously deepened, market-oriented system and mechanism for resources allocation among governments, scientific research agencies and enterprises are thrown into confusion because governmental purchase for scientific and technological achievements deviates from market principle and because the enterprises and applicable scientific and technological agencies are still allocating the scientific and technological resources by non-market-oriented method. As a result, China should implement double-orbit operation mechanism between “governmental administration for scientific and technological affairs” and “applicable technology market”, emphasize double-orbit parallel mechanism between “public appropriation” and “contracted purchase” in the management of scientific and technological affairs, rectify public expenditure approval-examination system in the contracted purchase and set up and perfect market-oriented resources allocation operation mechanism in applicable scientific and technological market.
