The Measurement And Comparison Of Antarctic Krill Capacity Utilization In 48.1, 48.2 And 58.4 Subareas

In this paper, the fishing data of Longteng vessel in 48.1, 48.2 and 58.4 subareas in 2018 are analyzed by the DEA method. Taking times of operation, operating time and wrap tension as input factors, the catch as output factor for the analysis. The capacity utilization and target input are obtained, pure technology efficiency and scale efficiency are summarized in time series, no-deflection capacity utilization are calculated, the rationality of input allocation and the input impact on capacity utilization are evaluated. It is conducted by comparison analysis: in 58.4 subarea, the pure technology efficiency fluctuates obviously and has no growth trend, the production scale is on the rise, but the capacity utilization does not increases proportional to the growth of scale efficiency. There exists a large proportion of input waste, the scale needs to be optimized continually. In 48.1 subarea, capacity utilization and the scale efficiency trend gradually decreases, and the technical efficiency also has some low value. The resources of the subarea are sufficient, and the capacity utilization is influenced by the technology level and the allocation of input. The rational allocation of input and improving the technical level is the key. In 48.2 subarea, the capacity utilization and the technical efficiency trend firstly increases then decreases, the capacity utilization is greatly influenced by the technical level. The production scale and variable input allocation are most reasonable in the three subareas, but the production input still has some room for adjustment.
