Popis: In recent years, the marine economy of China has experienced rapid growth, and the strategy of marine power also drove the development of the marine economy. The sea is a natural treasure that can provide rich resources. However, excessive consumption of natural resources and pollution problems of the ecological environment continue to become worse due to resource utilization inefficiency and disorderliness. Determining how to protect the environment on the basis of economic development is becoming a focus of attention. Research on the value of marine bioresources has great effects on preparing the balance sheet of resources. Accordingly, the present paper evaluates the value of marine bioresources in Shandong province offshore in 2014 by using the market valuation method, coefficients method, productivity change method, results reference method and contingent valuation method. In 2014, the total economic value of marine bioresources in Shandong province was $47.0533 billion, the direct use value was $9.3872 billion (in which the cultural research value was $0.7587 billion and recreational function value was $2.9413 billion), the indirect use value was $30.3469 billion, and the social value was $7.3192 billion. The indirect use value accounts for the largest proportion (64.49%), the direct use value accounts for 19.95%, far less than the indirect use value, and the social value accounts for a much smaller proportion, only 15.56%. And then the valuation results in the present study were used to analyze the reason for changes of ending value in the marine bioresources balance sheet. Suggestions were also put forward in the end. First, the public's understanding of the economic value of marine bioresources should be strengthened and the protection of marine bioresources should be increased, in order to promote the reasonable utilization of resources. Second, the potential value of cultural research for marine bioresources should be increased. Third, the stock quantity and value of marine bioresources in Shandong province should be evaluated, and a balance sheet of marine bioresources should be set up, in order to scientifically manage and constantly use marine bioresources in Shandong province, and promote the construction of an ecological civilization in China.
