Laver is one of the most necessary and seasonal items in Korean food from oldtimes. Laver is lagely eaten is dried form, and its supply depends entirely upon culture weeds. The history of laver culture in Korea about sixty or seventy years is older than in Japan. Significance of laver culture is divided into two aspects, one is food supply in the nation, and the other is export to other countries. Houses engaged in laver culture are about fourty thousands, and laver production in 1972 is estimated as 1,3 billon sheets. (1 sheet is a dried laver of 20 ㎝ sq, in the shape of paper) Especially meaning of laver production is the concentration of labour input, and systematic management of labour. From around 1920, the method of laver culture was introduced by Japanese Imperialism for mono culture in shallow seas, and mass products of laver is provided to Japan market. DOMESTIC MARKET Fundamental consume function calculated as below, D_(85.71)=16354 Y^(0.471) P^(-1.0668) where D is total laver demand, Y income variable, P price variable. It means income elasticity is 476, in the whole country, and price elasticity is 1,07. But generally income elasticity is higher in urban area than in rural area, as shown at 1,3 in Seoul city. Expence of laver in house expenditure is mutually correlated with another expence, See Table 12 about the relative function. See Table 14 and 16 about the relation between the gathering and the changes of price in auction, wholesale and retail. price support system is for two effects, one of which is constraint of the upper price, the other is rise of the lower price. Before the system control, the equation in three year average calculated as below, Y_b= 18,907.7455 + 15435.9364 t (γ=0.98) where the origin t=0 is the November and the units are month. Post the system control, Y_p= 30,047.9636 + 1,631.1727 t (γ=0.97) therefore, this system has an effect only on the rise of lower price. Average annual margins of laver products at four market levels according to the consumer spent is below. Havesting │Wholesaling │Retailing │Consumer 51.6 │ 16.3 │ 32.1 │ 100 EXPORTING MARKET Japanese demand function of laver products is, Log D=5,289 +1,108 Log Y-1,395 Log P (γ=0.987) where D is Japanese laver demand, Y income variable, P price variable, accordng to which income elasticity is 1.1 and price elasticity is 1.4. Laver production in 1970 the highest record till then, is estimated as six billion sheets. But the recent improvement of laver culture techniques, the production of seeds and freezing storage of seeds has been stabilized. Futher new culture farms have been developed by means of break-water fences or by floating culture method. These improvements have been backed up with increased demand of laver products. Import quantity and price of Korean laver products are restrained by three organizations, that is producer, distributor and cosumer. This relationship calculated by regression equation shows that import is influenced only producer organization, at the sacrifice of consumer profit. For increase to export of laver products, we urgently require to open foreign trade of laver products for Japanese consumer, and Japan has political responsibility to solve Korean laver structure. But with long run timeseries, as regards Japanese production and import quantity, importing function shows increasing trend as below, 250 million sheets <3,947.1674+0.005L_g> 600 million sheets where L_q is relative production quantity of laver in Japan. (unit; 100 thousand sheets) Our Export effort should be put on the highly processed products whithin the restraind quota.

Korea is a peninsular country surrounded by seas on three sides, and the fishing industry has carried out the service of suppling to the people with important anima protein. The distribution of fishery products has very complicated structures, because the production is in charge of small producers scattering along the coast all over the country, while consumpstion is made by separate homes in areas away from producing district. The relation between these two factors the structures make very complicated. The most typical and special structures of fishery distribution are distinguished in two, that is, one is landing market, the other is inland market. Landing markets have been monopolized by fishermen's cooperatives, providing with landing facilities and building sites. Fish markets played not only an important role in the landing, but distribution and price determination of catches by auction or tender. Inland markets are two types of wholesale market in consuming center, one is the terminal market for urban consumers, the other type is the local market for rural consumers. Fundamental functions of landing markets are gathering, assessment, and distribution functions. Gathering function is in charge of wholesaler in fishery cooperative. Gathering amounts are equal to gathering capacity of wholesaler and transact ability of licensed dealers as shown below model. Gathering amount =f·gathering capacity(=pre price·landing facility·account of wholesaler·distance of fishing ground·conveniency purchasing·home port)=f·transact ability of licensed dealers ≒f·population of port, and table 1 indicates these relationship. Assessment and distribution functions are in charge of licensed dealers in consumption side. Assessment function should bring the value in production activity through the auction between the cooperative seller and the licensed dealer as buyer. For fair trade transaction in auction, the free competition is supposed to be a prerequisite among the licensed dealers. The ideal condition for free competition is sameness in the scale of buying amount by licensed dealers, but it is almost impossible to attain its goal in actual marketing. For free competition, a normal distribution of licensed dealers scale is needed. Frequency distribution of scale, as shown in table 8, has the definite propensity of the skewness to the small. Regression equation of ranking and buying amount is shown in table 9, in the semi-log curve. Its reliance is about 95% of the actual buying amount of licensed dealers in Busan Fish Market. There are a number of similar concepts, i.e., middleman, jobber, bidder, commission merchant, broker etc., but these concepts do not exactly correspond to the idea which is supposed to express the intermediary nature of the licensed dealer above. The bidding and other transactions of the licensed deales are on the basis of the self accounting and self risk. The landing markets where the landing of more than ordinary catches is expected are divided into two types. One is L.D.Wholesale, who deal with inland forwarding. The other is L.D. retail, who sell to retailer in the market around the port. The diverging point of distribution function in licensed dealers is shown in the fig.3. The point A is buying amount of ranking 1 and total amount of buy is △ oAa, the line Aa was determined according to them. The point b is number of total licensed dealers, and total amount of buy is △ oBb, the line Bb was determined according to them. The point P is expected to be compromise point between large and small scales. And it is also diverging point of fowarding to inland market and selling to the near retailers. The range from O to Xm indicates L.D. wholesale, that from Xm to b is L.D. retail. L.D. wholesale actually gets revenue on commission basis and L.D. retail on commercial basis, as shown in table 11. For achieving efficiency of marketing, L.D. retaile should not get revenue on commercial basis, but on commission basis for consumers. For L.D. wholesale, inland terminal market system needs to be changed from simple wholesaler system into multiple wholesaler system, and actual gathering dealer should be converted to legal wholesaler. After channel structure becomes convergent to terminal market system, then it should be divergent to another channel structure, like big retailers are connected to landing markets. Consequently business safety and growth of scale will be guaranteed to licensed dealers of landing markets. The small scale of retailers is the main factor of the loss of producers and consumers, which is suffered by the lack of economy in scale. In order to minimize the loss, i.e. high margin and unhygienic transaction, L.D. retail should cooperate with each other and need to restrain retailers with license. Then the scale of retailers will be grown and business safety be guaranteed to licensed dealers.
