The purpose of this study is to identify the leading price between Jeju and Wando’s oliver flounder producer price and to analyze the dynamic effect of the regional producer price using the panel VAR model. In the process of analysis, it was confirmed that there are unit roots in the monthly data of Jeju and Wando’s oliver flounder producer price. So, in order to avoid spurious regression, the rate change of producer price which carries out log difference was used in the analysis. As a result of the analysis, first, the panel Granger causality test showed that the influence of the change rate of producer price in oliver flounder in Jeju was slightly larger than that in Wando, but it was found that each region all leads the change rate of the producer price in oliver flounder. Second, the panel VAR estimation showed that the rate change of producer price in Jeju and Wando a month ago had a statistically significant effect on the change rate of producer price of each region. Third, the impulse response analysis indicated that other regions are affected a little more than the same region in case of the occurrence of the impact on the error terms of the change rate of produce price in Jeju and Wando oliver flounder. Fourth, the variance decomposition analysis showed that the change rate of producer price in the two regions was higher explained by Jeju compared to Wando. In conclusion, it is expected that the above results can not only be useful as basic data for the stabilization of oliver flounder producer price and the establishment of policies for easing volatility but can also help the oliver flounder industry operate its business.

해양에서 이산화탄소 증가에 따른 해양산성화가 넙치 치어의 성장에 미치는 영향을 조사하기 위하여 현장 메조코즘 실험을 실시하였다. 동해 남부에 위치한 기장군 장안읍의 사질저질에서 실험군(이산화탄소 주입)과 대조군의 실험장비를 설치하여 43일 동안 총 447개체 (실험군 223개체, 대조군 224개체)를 대상으로 실시하였다. 실험군의 pH는 평균 7.63±0.13, 이산화탄소 (fCO2)농도는 평균 1660±540 μatm로 2100년도에 예상되는 수준으로 (IPCC 2007) 유지하였으며, 대조구는 현재 기장군 장안읍 해역의 해양환경으로 유지하였다. 실험기간동안 사망률은 실험군과 대조군 사이에서 큰 차이를 나타내지 않았고 시간이 지남에 따라 감소하는 경향을 나타내었다. 넙치 치어의 체장과 체중은 대조군에서 더 큰 증가양상을 나타내어, 그 결과 대조군에서 더 큰 성장률(specific growth rate)을 보였다. 결론적으로 본 연구는 해양에서 이산화탄소 농도의 증가는 넙치 치어의 초기 성장에 영향을 줄 수 있는 가능성을 제시하였다.
