农业技术创新和制度创新是资源禀富程度与市场需求变化诱导的结果.种子产业发展需要制度创新激发活力,推动育种技术的商业化转移和种子产业内部结构调整.商业育种体现市场驱动、法制化管理和自我约束的原则,以市场需求为导向培育新品种,根据市场要求改革运行机制.商业育种建立在高投入的基础之上,但简化了某些环节,形成流水线式的大规模育种.育种技术的商业化转移需要3个基本条件,即:形成技术市场,建立知识产权保护制度和大量非政府资金投入农业技术领域.为了促进玉米育种的商业化转移,应淡化玉米种子产业的政府行为,逐渐以商业行为取而代之.在改革管理体制的过程中,要建立以国家投资为主的、多元化的农业科研投资保障体系.“,”Agricultural technology innovation is induced by factor endowments and market demand, which further induces institutional innovation. Development of seed industry requires institutional innovations that stimulate the competition and promote the transition of current hinghly planned and administively intervened hybrid maize breeding and diffusion system into a more commercialized seed industry system. Hybrid maize breeding in commercial system is driven by the market demand and managed by legislation. The market demand determines the direction of the breeding program and promotes the restructuring the operation system. The shifting of breeding technology into commercial system requires three prerquisites, that is formation of technology market, intellectual property right enforcement and promotion of non-public sector's investment in seed industry. Coordination between public and non-public(private)sectors is one of key factors affecting this transition. Intellectual property right protection, which stimulates and induces private capital investment in agricultural R and D,is a necessity during the institutional and management reforms.
