Abstract

Although the relationship between income and income inequality has previously been discussed, the present study applies a dynamic approach to analyze the specific relationship between forest household income and income inequality. For this analysis, a unit root test and a cointegration test were conducted to characterize the nature of income time-series data. After converting unstable time-series data into stable time-series data, a VAR model was estimated. Based on this model, an impulse-response was generated and variance-decomposition analysis was performed. These analyses showed that the effect of forest household income was relatively larger than that of the Gini coefficient, and that the impact of forest household income not only caused income to increase but also caused the Gini coefficient to decrease. In addition, the impact of the Gini coefficient had an impact on reducing forest household income and further increasing income inequality. We conclude that, with the aim of alleviating the inequality of forest household income, an income growth policy would be more effective than an income distribution policy.

이 연구는 소득과 불평등 간의 관계에 대한 다양한 논의가 진행되고 있는 가운데 임가의 소득과 소득불평등 간의 관계를 알아보기 위해 동태적 접근법을 통해 그 관계를 알아보고자 하는데 있다. 이를 위해 단위근 검정과 공적분 검정을 실시한 후 불안정한 시계열 자료를 안정적인 시계열 자료로 변환시킨 후 VAR 모형을 추정하였고 이를 바탕으로 충격반응, 분산분해 분석을 실시하였다. 분석결과, 임가 소득의 영향이 지니계수에 의한 영향에 비해 상대적으로 큰 것으로 나타났으며 임가 소득의 충격이 자체 소득을 증가시키는 방향으로 작용할 뿐만 아니라 지니계수를 감소시키는 영향을 주는 것으로 나타났다. 또한 지니계수의 충격은 임가 소득을 감소시키는 방향으로 영향을 미치며 소득불평등을 더욱 심화시키는 것을 보여주고 있다. 따라서 임가 소득불평등을 완화시키기 위해서는 소득분배 정책보다는 소득성장 정책이 보다 효과적일 수 있을 것이라는 결론을 얻을 수 있었다.
