The purpose of this study is to investigate the fishery perception and recreation fishing demand level of coastal waters ranch with the case in Tongyeong city's Bijin-do Yongcho-do, Juk-do. The study conducts a survey of 27 fishermen and 113 recreation fishing tourists from September 26 to November 21, 2016. The major results of this study are as follows. First, the survey of fishery perception level suggests that the increase of fishery resources by Tongyeong-si coastal waters ranch project contributes to the rising income of fishermen, decreased fishing cost, and increased the number of tourists. Second, the survey of recreation fishing tourists's demand level suggests that a beautiful view, fish populations, kindness of residents, fishing point information, charter information, and the convenience of transportation are highly praised and highly regarded. However, links to nearby tourism, lodging facilities, and food information that can increase the income of fishermen is poorly praised. Therefore, this study suggests that a careful marine policy with fishery resource creation should be followed for marine fishing village tourism consumer's benefits in order to increase fishing village's income.

우리나라 항만공사의 경영효율성 평가 및 비교

강석규 ( Seok Kyu Kang ) 한국금융공학회 2020 금융공학연구 Vol.19 No.1

본 연구에서는 우리나라 항만공사를 대상으로 자료포락분석(DEA)기법을 이용하여 2015년부터 2018년까지 항만공사별로 순수기술효율성과 규모효율성을 구분하여 측정하고, 경영효율성을 평가·비교하였다. 이를 위하여 임직원수, 총자산, 자기자본을 투입변수로, 매출액, 영업이익, 순이익을 산출변수로 선정하였다. 본 연구의 결과는 다음과 같이 요약할 수 있다. 첫째, 연도별 우리나라 항만공사의 평균 기술 효율성은 2015년 0.8419, 2016년 0.8419, 2017년 0.8549, 2018년 0.8632로 측정되어 연도별로 전체 효율성이 개선되고 있음을 확인할 수 있다. 그러나 연도별 전체 평균 효율성이 85.05%로, 14.95% 정도 비효율적이며, 효율성 개선의 여지가 있음을 보여주고 있다. 둘째, 2018년 우리나라 항만공사의 평균 순수기술효율성과 규모효율성은각각 0.8817과 0.9754로 측정되어 비효율성의 원인이 주로 규모요인보다는 비능률적인 업무에 기인하고 있음을 보여준다. 셋째, 항만공사별로 보면, 항만공사 DMU1과 DMU3은 순수기술효율성과 규모효율성이 모두 1의 값으로 측정되어 능률적인 업무와 최적의 규모 하에서 효율성을 달성하고 있음을 보여준다. 그러나 나머지 항만공사의 경우 상대적으로 비효율적이며, 비효율성의 원인이 규모요인보다는 주로 순수기술요인인 비능률적인 업무요인에 의해 발생하고 있음을 보여주고 있다. 이들 항만공사의 경우, 경영효율성 개선전략으로 경영규모를 조정하는 것보다 영업비용과 영업외비용의 절감을 통하여 과소 영업이익 및 순이익을 큰 폭으로 증대시켜야 함을 보여주고 있다. The purpose of this study is to evaluate and compare the managerial efficiency of Port Authority in Korea by using data envelopment analysis(DEA) from 2015 to 2018. The DEA method is a relative evaluation method on the basis of linear programming. The main empirical results of this study are as follows. First, the average technical efficiency of Korea's port authority by year was measured at 0.8419 in 2015, 0.8419 in 2016, 0.8549 in 2017 and 0.8632 in 2018. It indicates that overall efficiency was improving on a yearly basis. However, the total average technical efficiency showed 85.05% which revealed about 14.95% of non-efficiency. Second, DMU1 and DMU3 port authorities show that both pure technology efficiency and scale efficiency are measured at a value of 1, indicating that efficiency is achieved under efficient work and optimum scale. However, it shows that the remaining port authorities are inefficient, and that the reason for inefficiency is due mainly to inefficiency, which is a net technology factor, rather than a scale factor. These port authorities show that they should increase their operating profits and net profits by reducing operating expenses and non-operating expenses rather than adjusting the size of the business with a strategy to improve management efficiency.

수산물의 유통단계별 가격간 장기균형관계와 인과성 분석 - 부산지역의 갈치 , 오징어를 중심으로 -

Fisheries products in Korea generally go through three markets, namely the wholesale market at production site (Market A), the wholesale market at consumption site (Market B), and the retail market (Market C), from producers to end consumers. As the products move from Market A through Market B to Market C, the marginal gap of prices asked in these markets demonstrates an apparent relationship. The producers, middlemen, consumers, and governmental departments concerned may influence the marketing prices of fisheries products. This study employing the cointegration theory tries to investigate whether causality of the price-setting among these markets exists and, if any, what it is. The authors have focused their attention on fisheries markets in Pusan, analyzing the long-run equilibrium relationship and causality between the prices of hairtail and squid among markets at difFerent levels. Data used in this study cover the period from August 1984 to December 1997 for hairtail, and the period from May 1989 to December 1997 for squid. The main findings of the study may be summarized as follows: First, regardless of the price time-series of hairtail and squid in individual market, the first difference is necessary for satisfying the stationary conditions since each time-series is a first integration. This means homogeneous integration of time-series, which is a requirement of the long-run equilibrium of prices at different markets, is satisfied. Second, the study of the long-run equilibrium relationship between the prices at Market A and Market B shows that a long-run equilibrium relationship does exist for selling prices of the two species at Market A and Market B. Third, the ECM (error correction model) used here to describe the long- and short-run dynamics of price change demonstrates that, in the case of squid, the price change in Market A will lead to a corresponding price change in Market B in the long-run period. In the short-run, however, the price at Market B is not only influenced by the price change in Market A but influence the price at Market A as well, that is, the prices between Market A and Market B have a feedback effect. It should be stressed that the limitation in data collection, which cover only two species of hairtail and squid, is likely to cause a sampling bias. Nonetheless, we may conclude that a dynamic relation in the formation of prices does exist in view of the transaction amount of species at different markets. It is believed that the conclusion drawn from this study would not only contribute to a long-lasted debate on the direction of causality of price-setting among academic circle and fishing community, but would provide a useful standard for the policy makers in charge of the price-setting of fisheries products as well.

The purpose of this study is to estimate the economic value of boat fishing experience marine tourism activity in Jeju Island``s Chagwido. The economic value is estimated as consumer surplus using count data models including the truncated Poisson model and the truncated negative binominal distribution model. This study collects the effective 504 questionnaires from boat fishing experience tourists in Jeju Island``s Chagwido. The truncated negative binominal distribution model was statistically more suitable and valid than other models. The truncated negative binominal distribution model was applied to estimate consumer surplus as economic value from boat fishing experience tourism activity in Jeju Island``s Chagwido. A consumer surplus value per trip was estimated as about 209,900 won. The annual economic value from boat fishing experience tourism activity was estimated as 273,700 won in Jeju Island``s Chagwido. Consequently, boat fishing experience marine tourism activity has a very large economic value in Jeju Island.

The purpose of this study is to investigate empirically interaction among the financing decision, investment decision, and profitability by using 41 fisheries corporations in Korea, and to suggest implications of the empirical results for government`s financial policy for fisheries corporations. Sample period is 19 years from 1982 till 2000. This analysis method employs the two stage least squares(2SLS) estimation method. From the results of regression analysis by 2SLS estimation method, the adjusted R2 values were high and the overall F values indicated significant. The empirical results of this study are as follows; (1) determinant factors of capital structure model for fisheries are profitability, firm-size, fisheries investment of total asset, and business risk. As pecking order theory explains, the higher is profitability the lower is debt ratio. The larger firm-size, the higher is debt ratio. The higher is fisheries investment of total asset and business risk, the higher is debt ratio. (2) determinant factors of investment model for fisheries are the change of sales, business risk, and debt ratio. These factors have positive relation to fisheries investment of total asset (3) determinant factors of profitability model for fisheries investment of total asset and debt ratio. These factors have negative relation to profitability. On the basis of analysis results, on the government`s financial policy for fisheries corporations, I suggests that with interest rate reduction, the government should lend more funds to solve the crisis in the financial structure of the fisheries firms.
