멸종위기종 황새의 보존와 복원 계획을 진행하는 과정에서 황새의 섭식행동과 서식지 환경을 이해하기 위하여 연구를 시작하였다. 이를 위하여 충북 청원군 미원면 화원리에 있는 산지형 습지 일부에 울타리를 치고 황새 암수의 한 쪽 날개의 첫째날개깃 일부를 잘라 방사하여, 6월 16일부터 7월 11일까지 25일간 일일 그리고 시간에 따른 섭식 행동 변화, 먹이 종류 및 양, 먹이 서식지 선택을 관찰하였다. 황새 암수의 하루 중 시간에 따른 섭식 시간과 휴식 시간

This paper is intended to study the relationship between state budget revenue and economic growth in Vietnam. The ordinary leastsquares regression method is used with secondary data collected from General Statistics Office of Vietnam in the period of 2000- 2017. Vietnamese state budget revenue includes domestic revenue (excluding oil revenue), oil revenue, custom duty revenue, and grants. The testing result shows that the state budget revenue has a positive correlation with economic growth of Vietnam. However, the components of state budget revenue have different levels of impact on the economy. Domestic revenue and oil revenue are statistically significant and have a positive effect on the economy, while the impact of custom duty revenue and grants on the economy is invisible. Vietnamese state budget revenue should be restructured toward the sustainability and by way of boosting the economy, specifically: (1) Increase the proportion of domestic revenue to state budget revenue and domestic revenue should be based on the ground of production and business activities rather than collection from state-owned assets; (2) Reduce the proportion of custom duty revenue and grants to state budget revenue; (3) Keep the volume and ratio of oil revenue in state budget revenue at an appropriate proportion.

Many authors have examined the impact of public spending on economic growth. This study uses ordinary least-squares technique to test the effect of state budget expenditure with two major components: development investment expenditure and recurrent expenditure on Vietnamese economy for the period 2000-2017. The empirical results show that the state budget expenditure of Vietnam has positive effect on the economy, however each main component has different impacts. Recurrent expenditure has significant positive impact on Vietnamese economy while there has no evidence to affirm the relationship between the development investment expenditure and the economic growth. Vietnamese government should restructure the state budget to enhance the positive effect on the economy. In the short run, Vietnam should not increase development investment expenditure due to low efficency in public investment. In the long run, it is necessary to economize recurrent expenditure to reserve a reasonable proportion of state budget for development investment expenditure to build infrastructure for developing the economy. The state budget expenditure should be restructured towards prioritizing recurrent expenditure on human and social relief, reducing public administration expenditure, allocating investment capital from the state budget for key and pervasive projects, avoiding spreading out investments as well as crowding out private investments.
