Problems in Rural Land Management Right Confirmation Pilots and the Countermeasures

The affirmation registration and certification of land contracted management right are the essential conditions for the effective promotion of land management right circulation and the development of agricultural moderate scale management. However, the following problems are found in the process of the pilot work： insufficient propaganda work, inconsistent recognition of affirmation registration work, low enthusiasm of grass-roots work; lack of unified regulations, each company working on their own; requiring large amount of manpower and resources for rural land contracted management rights, and severe shortage of national and municipal inputs; incomplete land ownership information and lack of marks between land plots, leading to resolving difficulty of the disputes; urgent need of strengthening subsequent work, untimely adjustment of related policies. Therefore, it needs to intensify propaganda, so that farmers can know the land right confirmation registration and certifi- cation, and recognize its importance; unify the introduction of job specification and results storage standard, making it convenient for the unified use of the results unified; set up special funds, and make experiments first in the areas with better economic conditions; establish arbitral institutions for land ownership disputes; earnestly make great effort to the supporting and subsequent work for right confirmation registration, and give full play to the role of land registration results.

Research on Rural Collective Land Ownership Confirmation Based on Unified Registration of Real Estate

Rural collective land ownership registration is a basic work to safeguard farmers＇ land rights and interests, and promote rural reform and development, which involves the vital interests of the peasants, and has great influence on the rural economic and social development. However, there are many problems in rural col- lective land ownership registration and certification, such as unclear rural land own- ership subject and nature; not unified understanding of registration, no high enthusi- asm of the grass-roots work; prominent registration policy contradictions, serious shortage of investment, which seriously affect the rural land ownership registration work. In order to solve these problems, some suggestions are put forward on pro- moting the rural land ownership registration work smoothly.

RCDS:a right-confirmable data-sharing model based on symbol mapping coding and blockchain

The problem of data right confirmation is a long-term bottleneck in data sharing.Existing methods for confirming data rights lack credibility owing to poor supervision,and work only with specific data types because of their technical limitations.The emergence of blockchain is followed by some new data-sharing models that may provide improved data security.However,few of these models perform well enough in confirming data rights because the data access could not be fully under the control of the blockchain facility.In view of this,we propose a right-confirmable data-sharing model named RCDS that features symbol mapping coding(SMC)and blockchain.With SMC,each party encodes its digital identity into the byte sequence of the shared data by generating a unique symbol mapping table,whereby declaration of data rights can be content-independent for any type and any volume of data.With blockchain,all data-sharing participants jointly supervise the delivery and the access to shared data,so that granting of data rights can be openly verified.The evaluation results show that RCDS is effective and practical in data-sharing applications that are conscientious about data right confirmation.
