Research On Assessment Methods And Application Of Loss Of Marine Fishery Resources Assets

China possesses a wealth of marine fishery resources which have made great contribution to the development of marine economy and national economy. However, the development potentiality of marine fishery is finite. In fact, there is low quality of fishery resources and parts of them are on the edge of extinction. These are no doubt in relation to the natural factors such as environment and ecology, but the origin is that fishery resources, as important state-owned resources assets, are poor in property right management and free use of it, which leads to the loss of marine fishery resources assets, influences directly on the sustainable development of marine fishery and undermines the foundation of the development of oceanic economy and even threatens the movement of the national economy. There is a lack of scientific, objective and systematic standard assessment of the loss recently and can't evaluate effect range of the loss on national economy and the way of maintenance and appreciation of fishery assets. Therefore, establishing the assessment theory and methods of the loss of marine fishery resources assets has becoming a burning issue of the research of fishery loss.The research is trying to put forward to the assessment methods and application of the loss of state-owned marine fishery resources assets based on the theories of natural resources assets assessment, loss of state-owned assets estimation and capital estimation in order to fill one of the gaps of it. The major innovation of the dissertation is summarized as follows:1,It firstly deals theoretically with the assessment of marine fishery resources assets and the theory of the loss of marine fishery resources assets is supplemented and perfected.2,It defines the loss of marine fishery resources assets and the loss of marine fishing resources assets and the loss of mariculture resources assets are put forward from the perspective of the resources exploitation. 3,It systematically constructs the methods and models of the loss of fishery resources assets assessment based on the analysis of its theory. The basic idea of the assessment is that the loss of state-owned marine fishery resources assets is net assets value the country should have plus assets value the country have had, the former of which contains capital value, ecological value, compensation value and the cost of development. The research provides scientific basis for the assets management of marine fishery resources and decision making.4,It establishes the value system of marine fishery resources assets constitution and models, and classification index of system of the value of marine fishing resources assets and mariculture resources assets from the point of state ownership, which can lay the theory basis for the assessment of fishery resources assets value.5,It builds the theory of the development coefficient of marine fishing resources assets'compensation value at relative stage. Marine fishing resources assets'compensation value is a dynamic process, the country couldn't compensate all loss of value at one time. So it should consider the bearing capacity of the society at various levels. The development coefficient of marine fishing resources assets'compensation value is based on the ratio between fishing output value and GDP combined with Engle coefficient and pearl curve, considering resources, economy and society parameter. It evades the difficulty of real value calculation and efficiently solves problems on the compensation value at different developing stage.6,It brings forward to the evaluation criteria and index of mariculture resources assets value and fuzzy comprehensive evaluation model to assess its compensation value and judge the value more operationally.7,It systematically calculates the loss value of marine fishery resources assets in Qingdao. The loss value of marine fishing resources assets is tested by using rent method, substitute cost method and stage coefficient method and so on. The loss value of mariculture resources assets is also manipulated by using income approach, fuzzy method and so on. The result reveals the total loss value of marine fishery resources assets in Qingdao is 209286.06 million yuan and the total value is 221464.86 million yuan, which accounts for 3.65 % of the ocean industry out value and 0.98% of GDP. The ownership value the country has had is significantly lower than the country should have and the plight is seriously.The results show that the loss assessment of marine fishery resources assets covers a wide range and various evaluation index and difficult data collection. However, the research has important realistic significance, which can not only offer the support of the loss problems of marine fishery resources assets research but also the reference of other ocean resources assets assessment.
