The Western liberal view of global governance can no longer effectively address the challenges facing the world today or respond to the demands of developing countries in the fields of human rights and development.Meanwhile,the United Nations human rights and development agenda also has its limitations.Against such a backdrop,China's path of human rights development has avoided the trap of human rights confrontation and the clash of civilizations.It has set an example of complementarity and positive interaction between human rights and development by unifying collective human rights with individual human rights and integrating the universality and particularity of human rights.Xi Jinping,general secretary of the Communist Party of China(CPC)Central Committee,delivered a speech at the 37th group study session of the Political Bureau of the CPC Central Committee on China's Path of Human Rights Development.This elevated China's human rights development to a new historical height.Practice has proved that China's concept and path of human rights in the new era have not only effectively promoted the development of its human rights cause,but also contributed Chinese wisdom to the global cause of human rights and development with a larger concept of human rights.Under the framework of the concept of building a community with a shared future for mankind,the Belt and Road Initiative,and the Global Development Initiative,China has contributed to enhancing the discourse power of developing countries in human rights and building a fairer,more just,more reasonable and more inclusive system for global human rights governance. 展开更多

In the reform process of the rural land property rights system,the incentive mechanism of the rural land property rights system has a crucial impact on the production activities of rural economic entities.Due to the different rights structures of the property rights system in different social and economic development stages,the land rights and interests enjoyed by rural economic subjects are different,and the degree of incentives for farmers is also different.This difference in incentives affects farmers investment in agricultural production factors,which in turn affects agricultural performance.This paper analyzes the incentive impacts of the structure of rural land property rights on the changes of farmers land rights and agricultural performance since the founding of the People s Republic of China,in order to further deepen the reform of the land system,protect the rights and interests of farmers,promote the modernization of agriculture and rural areas,and explore the realization form and operation mechanism of the rural collective land system in the new era. 展开更多

Mergers and acquisitions (M&A) are the important methods to quickly acquire external resources, achieve the economies of scale and the economies of scope, improve market share, and expand the scale of enterprise, while M&A performance is an important index to measure if enterprise M&A is successful. In this paper, the influence of entrepreneurs' political connection on the M&A driving factors and M&A efficiency of the enterprises with different property rights are analyzed using 357 mergers and acquisitions of China' s 189 listed companies in 2005-2011 as samples based on the distinction between political connection and the nature of enterprise property rights. The results show that the political connection plays a very significant positive influence on the M&A performances of the central state-owned enterprises and private enterprises, but exerts a very significant negative influence on the local state-owned enterprises; the intensity of entrepreneurs' political connection also plays a certain influence on enterprise merger and acquisition, and the central political connection and the local political connection are significantly different in the influence on the enterprise M&A performance. 展开更多

Quasi-NPR(negative Poisson’s ratio)steel is a new type of super bolt material with high strength,high ductility,and a micro-negative Poisson’s effect.This material overcomes the contrasting characteristics of the high strength and high ductility of steel and it has significant energy-absorbing characteristics,which is of high value in deep rock and soil support engineering.However,research on the shear resistance of quasi-NPR steel has not been carried out.To study the shear performance of quasi-NPR steel bolted rock joints,indoor shear tests of bolted rock joints under different normal stress conditions were carried out.Q235 steel and#45 steel,two representative ordinary bolt steels,were set up as a control group for comparative tests to compare and analyze the shear strength,deformation and instability mode,shear energy absorption characteristics,and bolting contribution of different types of bolts.The results show that the jointed rock masses without bolt reinforcement undergo brittle failure under shear load,while the bolted jointed rock masses show obvious ductile failure characteristics.The shear deformation ca-pacity of quasi-NPR steel is more than 3.5 times that of Q235 steel and#45 steel.No fracture occurs in the quasi-NPR steel during large shear deformation and it can provide stable shear resistance.However,the other two types of control bolts become fractured under the same conditions.Quasi-NPR steel has significant energy-absorbing characteristics under shear load and has obvious advantages in terms of absorbing the energy released by shear deformation of jointed rock masses as compared with ordinary steel.In particular,the shear force plays a major role in resisting the shear deformation of Q235 steel and#45 steel,therefore,fracture failure occurs under small bolt deformation.However,the axial force of quasi-NPR steel can be fully exerted when resisting joint shear deformation;the steel itself does not break when large shear deformation occurs,and the supporting effect of the jointed rock mass is effectively guaranteed. 展开更多
