산림(山林)의 다목적(多目的) 경영(經營)은 자원(資源)의 효율적(效率的)인 이용(利用)을 가능(可能)케 하는 경제학(經濟學) 이론(理論)의 한 응용예(應用例)로 볼 수 있다. 본고(本稿)에서 산림(山林)의 다목적(多目的) 이용(利用)을 뒷받침 해 주고 있는 경제학(經濟學) 이론(理論) 중(中) 두가지 중요(重要)한 이론(理論), 즉(卽) 기업이론(企業理論)과 자본이론(資本理論)의 산림경영적(山林經營的) 해석(解析)과 그 적용상(適用上)에 문제(問題)가 되고 있는 비목재(非木材) 효용(效用)의 측정방법(測定方法)을 검토(檢討)하였다. 또한, 실증적(實證的) 연구(硏究)로서 덕유산(德裕山) 국립공원(國立公園)의 산림휴양(山林休養) 가치(價値)를 Clawson의 여행비용법(旅行費用法)에 의하여 계측(計測)하였다. The concept of multiple-use forestry can be considered as a simple application of the economic theory which commands the efficient utilization of resources. This paper reviews two important branches of the economic theory-theory of the firm and the capital theory-and discusses various methodologies of measuring the non-timber benefits from the forest. In addition, an empirical analysis with an example of the Deogyu National Park is presented. For this purpose, the Clawson's Travel Cost Method was employed.
기후변화협약 대응을 위한 산림부문의 역할과 경기도의 대응

Forests play a crucial role in mitigating climate changes as a carbon sink. Forestry strategies for Gyeonggi province to expand carbon sink and to get carbon credit are as follows. (1) Enhancing forest management activities such as pruning and thinning (2) Planting more trees in marginal agricultural areas and urban spaces. (3) Protecting forest from wild fires, harmful insects, and diseases and minimizing conversion of forest-land to other uses. (4) Investing in overseas forest plantations securing GHG emission credits. (5) Using more wood products and biofuel. In order for the above strategies to be realized, regional forestry plan coupled with technical expertises and budget should be prepared.

This study was carried out to estimate long-term demand functions, and to project consumption of roundwood to the year 2030, using time series data for the period 1970-1990. Especially, the unique features of this study are in the estimation of demand functions for roundwood by species group and by end-use with help of dummy variables. It also, attempts to show how dummy variables can be utilized for improving the estimation result. The result of this study reveals that hardwood roundwood consumption is being substituted by softwood roundwood due to the rapid increase in the relative price of softwood, and this trend is expected to continue in the near future. The consumption of roundwood by mining industry is projected to fall as the coal :mining is expected to decline. The parametric estimates of timber demand function by species group and by end-use indicate that the demand for timber in Korea is more responsive to the performance of domestic economy as a whole, represented by GDP in this study, than to other variables such as own and substitute prices. The effects of population growth and substitute prices could not be determined.
산림자원관리정책이 국내재공급에 미치는 영향에 관한 연구

The objective of this study is to evaluate the impacts on the domestic timber supply potential of forest resources management policies such as the extention of forest management infrastruture and setting aside more forest lands for the provision of environmental goods. To this end, the domestic timber supply functions were estimated using time series data for the period 1970-1990 and were used to predict the future trends in timber production in the Republic of Korea. For this purpose, a set of scenarios based on the forest road density and forest inventory growth were designed for the next 40 years. The timber supply behavior in Korea was found to be different by species group : domestic supply of softwood roundwood is inelastic with respect to its ovum price while that of hardwood elastic. The effect of forest road construction on the domestic timber production seems to be insignificant yet. The model simulation aided by policy scenarios revealed that the future timber supply potential will be largely restricted if the policy option with emphasis on the provision of environmental goods from the forest resources were adopted.

To investigate the effects of national forest management on the regional community, the inter-relationship between the local communities and neighbouring forest owned by the state was surveyed in the three locations, namely pyungchang-gun, Bonghwa-gun, and Kwangyang-gun, which have a large area of national forest. The effect of national forest management on the local community was different depending upon the relationship between the local community and the national forest the resource base and infrastructure and facilities installed within the national forest. The major contribution of the national forest to regional society is the provision of land resources, forest products, employment opportunities, and social functions of forest. The supply of land resource from `he national forest has been increasing steadily due to the increase in demand for public facilities. About one quarter of household income in the forest villages surveyed came out of the sales of forest products, mainly non-timber products. Due to the low level of forest operations for timber production, there are very limited opportunities of employment provided by the national forest. And the use of forest roads by local residents was also to a limited extent. Therefore, it is suggested that the national frosts should be managed such that help to revive the economy of local communities which are disadvantaged in the national investment priority due to the low economic returns .
