離農現象과 農家 勞動利用構造에 關한 調査硏究

趙炳贊 동국대학교 농림과학연구소 1971 農林科學 論文集 Vol.4 No.-

As generally known, the rural labor force in Korea is characterized by 1) over-employment in the agricultural sector, 2) shortage of manpower in the farming season even under over-employment condition and) lower coefficient of labor utilization. These factors suggest that the agricultural labor in Korea is still in a premordern state. It is to be noticed that in the recent years our agricultural labor force has shown a tendency to decrease due to ever-increasing out-flow to urban communities, causing a severe shortage of manpower in the farming season which affects agricultural productivity in Korea. Keeping the above problems in mind, the author surveyed the rural labor force on a village in the suburb of Seoul, in order to analyze and investigate the aspects of leaving farms and structure of labor utilization. Village surveyed; Village of Yadang-dong, Yadang-ri, Kyoha-myon, Paju-kun, Kyunggi-do. Method of survey; Complete survey of 50 households which comprise the village. Dates of survey; August 1-31, 1970. The results obtained from this survey are summarized as follows; 1. Phenomenon of leaving farms (1) The out-flow of these villagers to urban communities was observed, in general, among the group of the high teens and the first half of forties. The leaving rate is higher in young group. Accordingly, the manpower of this village was old aged; i.e., 34.7% of the age group of 15-24, 32.1% of 25-34 and 22.6% of 35-44 left the village during a period of Jan. 1965-Aug. 1970. (2) The leaving rate is markedly high in the group of higher educational background; i.e.,3.4% of uneducated or under primary school graduates, 20.1% of primary school graduates, 21.7% of secondary school graduates, 42.9% of high school graduates and 88.9% of college or university graduates. (3) In order to analyze the effect of the scale of cultivated area and farm household income on the leaving farms, the correlation between the two factors was investgated, The resultes revealed very low degree of correlation between them. 2. Utilization structure of labor The number of working days per capita in a year and rate of labor consumption (utilization) was 164.0 days and 54.7% for male, 113.7 days and 37.9% for female, and the average of the both sexes was 137.9 days and 46.0%(The percentage is based on 300 working days in a year - 25 days in a month). Such low coefficient of labor utilization may be attributed to the following factors; (1) The seasonal change in the demand of manpower; because of simple cropping method in our country, which depends entirely upon seasonal factors. (2) The fact that most of youth group in the village tend to avoid farming work and to find other jobs because of their inferiority complex with agriculture. Most of them refuse to engage in agriculture even if in the unemployment status. (3) The low participating ratio of labors of both sexes in non-farming work in the farming community; because they are rarely given the opportunity to find and to be trained for a proper job in and around their farm village. 3. Factors determining the labor utilization Upon analyzing, as the determining factors of individual labor utilization, 1) age of laborer, 2) scale of cultivated land, 3) scale of farm household income, it is revealed that the most significant factor is the age of laborer. The age means working capacity of individual farmer and his position or responsibility in the household; i.o., dependent or not. 4. Conclusion (1) The out-flow of the young and educated from this village resulted in; 1) that the average age of the remaining labor is high, 2) that the educational level of the remaining labor is low, causing intellectual vacuum in the village. (2) Utilization of labor The rate of labor utilization in this village is very low, mainly from; 1) the long farmer's slack season caused by the mono-cropping system which depends upon entirely seasonal factor. 2) the difficulties to find proper work (especially non-farming)during the farming slack season. 3) traditional family system of Korea with large number of dependents who can and should work, but whose widely recognized unconscious privilege prevents their positive participation in the farming work.

主要農産物價格에 對한 供給反應分析

趙炳贊,金東敏 東國大學校 1975 論文集 Vol.14 No.-

In order to explore feasible alternative price policies, this study attempts to measure how farmers have responded to price changes of major agricultural products such as rice, barley and naked barley. Ferris model was carefully examined and a Cobb-douglas type production function was presented as an alternative approach to determine the relationships between the production and the environmental factors. Y=f(A.P.W.T) where, Y=Production. A=Area planted. P=Price level. W=Weather conditions, T=Technology level The underlying assumptions of the study can be summarized into the following four items. (1) Past prices strongly influenced farmers' price expectation. (2) Farmers would begin to respond in a significant way a year after the price had changed. (3) Farmers would keenly respond to increases of rice price in absolute terms due to the lack of competitive uses of paddy land. (4) Farmers would keenly respond to increases of barely and naked barley price in relative terms due to its fierce competition with other crops for upland usage. In testing the foregoing assumptions to be valid, a multiple regression in a log-log form was derived. logY=x_0+alogx_1+blogx_2+clogx_3+dlogx_4+elogx_5+flogD+glogT Where, Y=Production, kg. z_0=Constant. x_1=Area planted, ha. x_2=Farm gate price at the previous year, Won/Bag(80kg). x_3=Farm gate price at the current year, Won/Bag(80kg). x_4=Farmer's terms of trade at the previous year (Ratio of price index between farmers' selling and purchasing). x_5=Farmer's terms of trade at the current year. D=Dummy variable representing weather. T=Time variable (technology level). Time series data was collected from the official statistics of M.A.F. and N.A.C.F. and the computation procedure was easily done through K.I.S.T computer by using T.S.P.(Time series data processing) program package. As a result, we could select eight plausible equations (three for rice and barley respectingly, and two for naked barley) were selected to estimate the regression coefficients. Those equations showed statistically meaningful correlation coefficients and significantly acceptable "t" values. Looking carefully at these result equations, the following observations logically could be concluded. (i) Farmers seemed to respond in a significant way a year after the price had risen. (2) Farmers seemed to respond sharply to increases of rice price in absolute terms rather than relative terms. (3) Farmers seemed to respond considerably to price changes of naked barley in relative terms rather than absolute terms. (4) All crops but not for barley have positive correlations between production and area planted, and thus the size of the average farmers could be infered to be far bellow the economically optimum level. (5) Rice probuction could be seen to be heavily influenced by the weather factors, meanwhile barley production relatively by technology improvements to the greater extent. Finally it is highly recommendable that the government continue to follow or adopt the agricultural price support policy toward the direction of food self-sufficiency realized in near future.

花卉産業의 實態와 問題點 分析

趙炳贊 동국대학교 1985 論文集 Vol.24 No.-

With the economic development, it has become a universal trend that floriculture is one of the necessities of life. Accordingly, the demand for floriculture in Korea increases rapidly since 1970 with the rapid economic development, though, in 1975, per capita consumption of floriculture in Korea was 5% of Japan, 1.25% of America and less than 1% of Germany. However, in 1970s, the rate of increase of the demand per household in Korea is 700%, higher than that of Japan, 520%. It is true that floriculture industry in Korea has made a remarkable development due to the increase of the demand. Recently, Korea imports a lot of flowers as the domestic supply has been unable to meet inflated demands. As a result, Korea is a chronic crop importing country including floriculture, with a widening adverse balance of trade. It is urgently needed that Korea should grow and develop its floriculture as an essential industry. The problems of floriculture in Korea, in spite of the rapid development in 1970s, are: the poor capital and facilities due to the pettiness of the individual farmers, the decrease of the ratio of the big-scale farmers and increase of the petty farmers, the regional concentration and disparity in technique of cultivation due to the lack of recognition among the general people and diffusion of technique, the pre-modern market dominated by the oligarchic merchants. Thus, the following steps are necessary for the healthy growth and development of floriculture in Korea. 1. the general policies with new recognition and efforts for the development of floriculture, 2. the positive aid of fund and facilities to solve the pettiness of the farmers, 3. the establishment of the modern flower whole-sale markets to protect the farmers from the arbitrary exploitation by the pre-modern oligarchic merchants, 4. the organization of the floricultural farmers for direct and joint sale, 5. the development and equalization of the technique for the cultivation and merchandising of the floriculture, 6. the positive development of the demand of floriculture for the people's emotional refinement and labor efficiency through th environmental beautification, 7. the exploitation of the oversea markets.

小賣市場에 있어서의 「단골去來關係」에 관한 調査硏究 : 生活必需品을 中心으로 in case of the main necessaries of life

趙炳贊 東國大學校 1977 論文集 Vol.16 No.-

This survey was conducted among 332 housewives throughout Seoul for a month (June 15, 1977-July 15, 1977). The survey is to examine the fixed relationship of customer and retailer in the retail market of the necessaries of life. The contents and result of the survey are as follws. Most items of the necessaries of life are purchased mainly by housewives who show the strong tendency to have the fixed retail shops in each item. The rate of the fixed shop by the items is; fuel 88.0% food 59.2% garment 50.3%. The itmized rate is; 1. yeontan (coal) 95.2% 2. grain 89.9% 3. kerosen 86.0% 4. gas (L.P.G.) 73.3% 5. meat 70.9% 6. garment (tailored) 64.7% 7. food (others) 54.5% 8. subsidiary food(except meat) 51.8% 9. underwear 50.0% 10. fish 49.0% 11. fruit 39.1% 12. garment (ready-made) 36.2% The housewives usually have one or two fixed retail shops in each item and the dominant factor in the choice of fuel and food is the distance from houses. The most important factor in the choice is "the creditability" and "the lack of kind service" in the avoidance. It is interesting to note that the outward economical inducement such as bargaining in price and quantity is not so important as it was generally believed to be. The important factors in the success of the retail shop, which is measured in the terms of the number of the fixed customers, and the achievement of the larger purposes of (a) rationalization of marketing, (b) maximization of the profit of the retailers, (c) protection of the consumers seems to be (a) creditability (b) kind service (c) list-price system. To achieve the above mentioned purpose, the effort for improvement on the part of the retailers and the proper and appropriate guidance on the part of the big industries and the government agencies concerned as the authority in charge of the marketing are needed. "The Model Retail Shop" must be selected on the basis of "the creditability" and "the kind service", along with the list-price and the issuance of the receipt.
