[Method] Comparison of the incidence of weeds, sheath blight and insects pest under rice-duck mutualism, conventional cultivation and control treatment, the yield and economic benefits were analyzed under the 3 treatments. [Result] Average occurrence of weeds in rice-duck mutualism group decreased by 2.33 and 52.0g ind/m^2 compared with that in conventional cultivation and control treatment ; the control rate of mutualism was up to 75% against rice hopper, but just between 25% -60% against rice leaf roller and Chilo suppressalis. The rates of diseased plant and diseased bell against rice sheath blight were higher and disease indices were lower compared with control group. The yield of mutualism group was identical with conventional cultivation, Which was greatly higher than that of control group. The results suggested an higher economic benefits and lower cost benefit ratio for rice-duck mutualism treatment. [Conclusion] Rice-duck mutualism gives birth to a positive effect to control the diseases, insect pests and weeds, as well as to economic benefits, providing basis on extension of rice-duck mutualism system.展开更多

Economic law is a general term of legal nomas to adjust social relations occurred in the course of state regulation of the economy, so that to protect state regulation, and promote social and economic coordination, stability and development. From the view of the generation of the law, economic law is generated after the emergence of the socialization of production and monopoly to protect the public interest. Economic law is bound to reflect social justice in the redistribution process of interests. Legislative intent of economic law to maintain a fair society is reflected through the redistribution process of the interests. Redistribution of the economic law is an important means to achieve social justice.展开更多

As some commentators have pointed out, the public interest is an ancient and new topic. It＇s a highly abstract prone to ambiguities and shortcomings of the concept. And it＇s also a basket that strange, confused and can not be discarded. Even critics simply deny the existence of public interest and regard the public interest as a myth. As it＇s difficult to define the public interest from political perspective, a democratic theory, legal perspective a theory of law, economic perspective a public choice theory, philosophical perspective a public philosophy, and other common perspective. The paper explores the law theory of public interest from the framework of the overflow theory and the perspective of the concept function, and provides an easy to use identification method of public interest for the judicial practice and administrative practices.展开更多

It elaborates we must adhere to stabilize and improve the rural basic management systems, give farmers more fully right to protect the land, develop rural land contract management rights transfer, and promote agricultural innovation and industrial organization.展开更多
