Study On Productivity Of Mariculture

In the background of rural revitalization,vigorously developing agriculture is the only way to revitalize the countryside,and fisheries as an important part of agriculture naturally cannot be ignored,while mariculture as an important part of fisheries is related to the development of fisheries.In order to better develop the mariculture industry,this paper starts from improving the production efficiency of mariculture,based on the efficiency theory and the theory of sustainable agricultural development,on the basis of systematic analysis of the current development status of China’s mariculture industry,re-examine the problems it faces,and collect relevant data from 10 mariculture provinces in China from 2016 to 2020,and adopt the DEA-Tobit two-step method for empirical The results show that the three efficiency values of mariculture in most provinces,i.e.,comprehensive efficiency,pure technical efficiency and scale efficiency,are high,while comprehensive efficiency is mainly affected by scale efficiency,and only a small number of provinces have redundant inputs of production materials;the factors affecting the efficiency of mariculture production,in order from high to low,are disaster rate,financial expenditure,per capita disposable income,while the number of training periods and the number of technical extension institutions with intermediate and above The effect of the number of training periods and the percentage of technical extension institutions with intermediate and above titles on efficiency was not significant.Therefore,to further improve the efficiency of mariculture production,it is proposed to strengthen the promotion of mariculture technology,improve the competitiveness of aquatic product markets,improve the means of coping with various types of disasters,promote sustainable development,build a mariculture industrial system to achieve increased production and income,increase disposable income per capita,and attract excellent practitioners.
