- Abstract
- In this study at first the technical efficiency (TE), meta-frontier, and technological gap ratios (TGR) of six world fishery regions in the years 1960-2010 were analyzed. The efficiency level was calculated for Europe, Asia, North and Central America, Africa, South America, and Oceania, based on countries from which adequate data were available. Although many country’s efficiency levels are high within their region, on a global scale few can be considered efficient. This shows that today’s worldwide fishery is facing a lack of cooperation.
After analyzing the global and regional, it is focused on Korea, China and Japan region using Meta-frontier. The meta-frontier enables the computation of comparable technical efficiencies for these countries. Also, this paper enables the technology gaps to be estimated relative to the potential technology available to the fishery sector in South Korea, China and Japan as in this region.
The study showed high level of efficiency for Korean fisheries, that is why it is focused more on answer the question why Korean efficiency level is high. For this reason, the management tool that Korean government have used in order to overcome the overcapacity issue in was analyzed.
To address the reasons why Korean fishery regained its efficiency, Data Envelopment Analysis (DEA) method was used and showed which fisheries are over- or under- productive. To investigate the effectiveness of the buyback program, data were collected for 18 fisheries (9 each of coastal and offshore fisheries) for two periods from 1991 to 2001 and 2002 to 2012. A distance function approach was used, because the data for this time period consisted of input (number of vessels, tonnage horse power) and output (fish harvest) values, with no corresponding input prices. Since there is a dearth of cost data and questionable market price data in fisheries, the Malmquist Index (MI) was calculated to study productivity of the fisheries. There were two different scenarios analyzed for applying the buyback program in Coastal and Offshore fisheries of South Korea in order to reduce the over-capacity problem. The first scenario was considered as before and after the buyback program show it effects. The result was analyzed for two 11 years periods from 1991 to 2001 and 2002 to 2012. The second scenario was considered as with or without buy back program. In the second scenario, the number of vessels were considered fix from 1994 in Korean offshore fisheries and from 2003 in Korean Coastal fisheries. In the first scenario, results showed 2 coastal fishery sectors and 1 offshore fishery need more intensive management. In the second scenario, in the case of without buyback program the productivity stayed low in both coastal and offshore fisheries of Korea. The Korean government has introduced a fish stock rebuilding plan in parallel with the vessel buyback program.
