The case study of the Cooperatives' members and Sincere Forest Managers/Forest Successors was carried out to find the determinants affecting the forest investment of private forest owners and analyze their effects on it. For this the landowners' forest investment probability function was estimated using the logistical regression model. The results showed that the forest investment of the Cooperatives' members was the function of forest area, stand age, forest income, and technical assistance. Three of the variables (forest income, forest area, and technical assistance) exhibited a positive effect on the forest investment as expected, while stand age showed a negative effect unlike the expectation of the study. In case of Sincere Forest Managers and Forest Successors forest area, distance(1)(distance from forest to road accessible by vehicle), knowledge of financing program, and forest income were significant indicators for the forest investment. All these variables showed the expected signs; forest area, knowledge of financing, and forest income had a positive effect on the forest investment, and distance(1) showed a negative effect.

This study is to give investment information to someone who will manage a chestnut orchard or has been managing a chestnut orchard by means of profit by producers' chestnut price and a term of investment retrieval because of fluctuations in chestnut prices in the opening time by FTA. This study, hence, evaluated 133 families who manage a chestnut orchard at Jin-ju, San-cheoung in Gyeong-nam, Gu-rae in Jeon-nam, Gong-ju, Bu-yeo, Cheoung-yang in Chung-nam. This study used IRR, B/C Ration, NPV and the break-even point sales methods. As the result of this study, there are investment value at much than 1,140 won/kg including wages themselves at 4% interest, however, there are not investment value at less than 1,140 won/kg in the same economic condition. Furthermore, an investor could retrieve the investment at sixteen year and the break-even point sales is 32,963,000 won/ha. If 3,000 won/kg, an investor could retrieve the investment at nine year and the break-even point sales is 15,176,000 won.

The study is focused on comparing the perception of forest investment by two types of forest owners, ordinary forest owners (OFOs) and forestry successors and model forest owners(FSMFOs). The results show that FSMFOs' perception of forest investment is relatively high compared with OFOs' perception. The details are as follows; 1. In the general status, the education and income levels of FSMFOs are higher than those of OFOs, and FSMFOs are engaged in various kinds of jobs while OFOs are inclined to lean toward farming. 2. Of the motives to own forests, partial-purchase and -inheritance is the most of FSMFOs(41.2%) and inheritance the most of OFOs(40.9%) 3. The number of FSMFOs who had made forest investment and applied government support is more than that of OFOs. 4. FSMFOs know government support better than OFOs do, while both show lukewarmness on weather the support is carried out according to the rules.

This study was carried out to improve forest tax system corresponding to Korean forestry status. Especially, special regard was paled in order to promote forest investment as a result of improvement measures. As a result of this study, the establishment of new system which allow deduction as a loss when forest investment occurred is more effective than present forest income tax system, which gives tax-exemption on cutting of artificial forests. Some detailed adoption technique of that system was examined in various viewpoint. Also, it is indicated that this improvement measures was already adopted generally in some developed countries.

This study examined the economic effects of low tree-form culture, Cost-Benefit analysis was done based on additional costs and benefits from investment in low tree-form culture. In addition, this study analysed the sensitivity of profitability due to the changes in chestnut prices and wages. Investment in low tree-form culture was analysed to be profitable in Chungju, Gongju and Buyeo areas but in Jinju area. Sensitivity analysis of changes in prices and wages also showed that investment in low tree-form culture was economically feasible in Chungju, Gongju and Buyeo areas except for Jinju area.

The energy use of forest biomass is crucial to deal with climate change and achieve the carbon-neutral goal. This study aims to analyze the economic feasibility of forest biomass thermal energy facilities and calculate the optimal subsidy level of heat supply to ensure continued operation of the facilities. To achieve this aim, the net present value approach (NPV) and call option price model are adopted considering wood chip price volatilities. The Forest Energy Self-Sufficient Village Project financed by Korea Forest Service is considered as the research case study. In our analysis, when 50% of the initial investment is given to the subsidies and RECs are applied to only power generation, NPV and IRR are both negative and the investment value using the real option model is also zero. We concluded that some heat subsidies should be acknowledged to keep the facilities operating. Besides, the simulation results reveal reliable economic values when the heating subsidy is priced at KRW 0.0248 per kcal.

For the last 10 years, there were also a lot of exchanges and cooperations between North and South Korea's local governments. Dealing with these exchanges more systematically, local governments had issued many regulations. But in the law level, the current laws regulating exchanges and cooperations between North and South Korea lacked care in the role of local governments in the course of Korea reunification. Therefore, it is necessary to redesign the legal system to support and promote the role of local governments in unification affairs. The purpose of this study is to seek answers to a question how the Inter-Korea forest cooperation project effect on regional economy compared with other forest sectors. Results of this study proved that Inter-Korea forest cooperation project effects on regional economy positively as 'plus investment', not negatively. Forest cooperation project will be resolve Inter-Korea conflicts more peacefully. So government should be supported continuously in the long run in order to raise the performance.

This study was conducted to provide resonable price of timber that come out from certified forests for sustainable forest management. To accomplish this study objectives, we analyzed compound interest method, willingness to pay (WTP) and price sensitivity measurement (PSM) when buying certified pulp. In case of compound interest method, we used prime cost by average price per ha of each area (Hongcheon, Inje, Shinnam) and unit price that add up the pulp price and investment costs. Interest rate reflects 2 to 6% and investment period apply to 5 years. WTP and PSM data were collected from questionnaire survey. As a result, if apply to interest rate of 2% and investment period of 3 years, result values are quite similar to WTP of 5% and optimal pricing point of PSM. That also showed similar pattern in each area.

The study was carried out to investigate the surroundings and benefit analysis on the planting investment of Thailand for securing a stable supply of timber through overseas planting, The results show that Thailand government is planing to increase the coverage of forest from 25% to 40%, encouraging planting over the country. More advantages and incentives are given in the investments in planting and wood-processing industries such as plywood, veneer, and chip & hard board, etc. In Thailand Eucalyptus species which are most popular in planting as they are lucratively used as a material of pulp. The Internal rate of return (IRR) in the study was ranged from 29.1 % to 59.3.

This paper analyzes the feasibility of using machine learning methods to forecast the employment. The machine learning methods, such as decision tree, artificial neural network, and ensemble models such as random forest and gradient boosting regression tree were used to forecast the employment in Busan regional economy. The following were the main findings of the comparison of their predictive abilities. First, the forecasting power of machine learning methods can predict the employment well. Second, the forecasting values for the employment by decision tree models appeared somewhat differently according to the depth of decision trees. Third, the predictive power of artificial neural network model, however, does not show the high predictive power. Fourth, the ensemble models such as random forest and gradient boosting regression tree model show the higher predictive power. Thus, since the machine learning method can accurately predict the employment, we need to improve the accuracy of forecasting employment with the use of machine learning methods.
