Impacts of Changes in Structure of Rural Land Property Rights on Agricultural Performance

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.

Analysis on Internal Growth Potential of Agriculture Under the Agricultural Structure Adjustment in Xinjiang

Agricultural structure adjustment has always been the important factors influencing Xinjiang agricultural internal income growth.On the basis of the planting scale,productivity and price in 2010,the paper measured the contributions made by agricultural structure adjustment to Xinjiang agricultural internal income growth through structural optimization.Linear programming model was established by Lingo software,to optimize the structure of planting,horticulture,animal husbandry in Xinjiang and analyze the internal agricultural income growth potential.After structure optimization,Xinjiang agricultural production value will reach 1231.44×108yuan and the farmers'income of production and management will reach 9851yuan.The greatest potential for Xinjiang agricultural internal income growth was husbandry accounting for 41.33% of the total production value.The next one was horticulture,whose share of the total production value has raised to 17.43% from 10%.Fruit industry and animal husbandry will become the pillars of future income growth.There are still some income growth spaces in Xinjiang internal agriculture though the agricultural structure adjustment.The agricultural production value will increase by 44.32%and farmers'production and management income will increase by 68.83%.That will be one of the most important ways to tap the future potential of agriculture internal income growth.

Optimal Scheme Selection of Agricultural Production Structure Adjustment——Based on DEA Model; Punjab(Pakistan)

This paper used the modern evaluation method of DEA （Data Envelopment Analysis） to assess the comparative efficiency and then on the basis of this among multiple schemes chose the optimal scheme of agricultural production structure adjustment. Based on the results of DEA model, we dissected scale advantages of each discretionary scheme or plan. We examined scale advantages of each discretionary scheme, tested profoundly a definitive purpose behind not-DEA efficient, which elucidated the system and methodology to enhance these discretionary plans. At the end, another method had been proposed to rank and select the optimal scheme. The research was important to guide the practice if the modification of agricultural production industrial structure was carded on.

Areal differentiation of virtual water for agricultural products and its effect on regional agricultural structure adjustment in China: 1995-2007

With a vast territory, the space-time distribution of water resources is uneven in China. There is a great dif ference in natural conditions and farmland management of agricuttural production in different regions. The areal differentiation of agricultural products virtual water is obvious. Comparison with the agricultural products virtual water from 1995 to 2007 in China shows an increase in the first ten vears and a little decrease in recent years. There has been a tendency of increase all the time in Northeast and Northwest. but a decrease after an increase firstly in other regions. The virtual water offood crops is the maximum which accounts for more than 70% in China. and that of vegetables is in a fast growth. The proportion of agricultural products virtual water to the total water resources in each region has a large difference, showing the imbalance of agricultural water in different regions, which accounts for 50%-90% in Northeast, and 125%-185% in North China. Under the guidance of virtual water strategy, based on the differences of resource endowment, each region should adjust agricultural structure, decide production by water, and select water suitable crops. In water-rich region, agricultural produets of high water consumption should be planted appropriately, which will make full use of the abundant local water resources. In water-shortage region the crop production of high water consumption and low efficiency should be depressed, and that of low water consumption and high efficiency should be supported and increased. It will achieve reasonable disposition of water resources, promote ecological restoration and environmental protection, as welt as ensure food security.

Analysis on Relationship between Adjustment of Agricultural Structure and Urbanization Development

As a part of certain region,agricultural development has inevitable connection with regional urbanization,and they are highly heterogeneous and complementary in space. Their internal relationship is manifested as agricultural structure suits demand of urbanization development through adjustment in the process of urbanization,while urbanization is based on development of regional agriculture. From history of world agriculture and urbanization development,agriculture firstly provides primitive accumulation for urbanization development,and drives regional urbanization through promoting agricultural development. When urbanization develops to certain stage,urbanization accumulation increases and reaches the goal of " boosting urbanization through agriculture". If urbanization develops slowly,agricultural adjustment will lack motive force. On the contrary,weak agricultural development will lead to stagnation of urbanization. Therefore,adjustment of agricultural structure and urbanization development are interconnected,mutually promoted and restricted,and interdependent.

Agricultural Production Structure Adjustment Scheme Evaluation and Selection Based on DEA Model for Punjab(Pakistan)

农户最低收购价预期与种植结构调整--来自农业生产性投资的调节检验

使用2018年湘、赣、苏三省水稻主产区农户调查数据,研究农户最低收购价预期对种植结构调整的作用机制及农业生产性投资的调节效应。实证结果显示,农户预期最低收购价下降对种植结构变化、调模式行为有显著正向影响,且预期降幅超线对调模式行为的影响更显著,表明最低收购价政策变化传递出较明显的种植结构调整效应。农户预期最低收购价下降、预期降幅超线和专用型设备投资对调面积行为的影响显著为负,且专用型设备投资与预期降幅超线交互项对调面积行为的负向作用更显著。这种负向调节效应源于农户专用型设备投资收益回报机制对水稻种植规模的“锚定”效应,使得专用型设备投资对农户面积减少行为有较大的延迟作用。未来种植结构调整应引导低端农产品向优质、品牌化转型,稳定农户生产性投资收益回报率预期,探索分类引导不同规模农户种植结构调整的政策。

国家所有制中的集体性产权:形成、特征与优化

改革开放以来,经过国家所有制内部产权结构的调整,我国国有企业逐步转变为拥有国家赋予自主经营权利、承担应尽责任、获得相应局部经济利益的产权主体。由此,在原来产权高度集中的国家所有制内部,就形成了一种过去没有的、由企业分别拥有和实施的财产权利。它存在于国家所有制之中,且不同于集体所有制之类的独立所有制形式,但不同国有企业作为一个集体在拥有份额上各有不同。国有企业内部形成的有集体差别的这种财产权利,可以称为国家所有制中的集体性产权。这种产权的存在没有改变企业全民所有的基本属性,其形成和运作过程具有附着性、有限性、排他性、可分解性、行为性和可变动性等特征。这种集体性产权的形成与发展对国有企业改革成效和国有企业全民属性发挥的影响利弊共存,必须在充分发挥其积极作用的同时防止其过度扩大。因此,要以习近平新时代中国特色社会主义思想为引领,深化国有企业改革,规范集体性产权关系中基本当事人的行为,以坚守企业全民所有制属性为底线,把握好集体性产权的合理界限。
