農家所得偏低一直是我國政府關心的議題,為提升農家所得,雲林縣政府及在地民眾更企圖藉開發六輕工業區來提升其農家所得,而一地之農家所得是否能因工業發展提升?真正能影響農家所得的因子又是為何?能得到問題的解答,方能有助於制定增加農家所得之有效政策。 首先,利用雲林地區之家庭收支調查資料並採最小平方法(OLS);次使用準縱橫資料(pseudo panel data)經採Hausman Test後,選擇最適估計模型進行迴歸估計,對雲林地區農家所得是否受六輕設廠營運影響及重要農家所得影響因子加以分析探討。實證結果顯示六輕設廠營運雖對該地區(雲林)實質農家所得(包含農業所得及非農業所得)無顯著的影響,但對地區人口就業仍提供相當的幫助,並使其農家所得相對其他地區高;實證結果亦顯示,可藉降低失業率及提升農家成員(含未來工作者)教育水準,以提升農家所得,而其他家庭成員的人力資本對農業所得亦可能產生所謂的「外溢效果」。
The low income of farm family has long been a matter of concern to our government. The Yunlin County Government and local people attempted to increase farm family income by developing the Sixth Naphtha Cracking Plant. Will the income of farm family from a land be improved due to industrial development? What are the real factors that affect farm family income? Obtaining answers to these questions will contribute to the development of effective policies to increase farm family income. The study first used the household income and expenditure survey data of Yunlin district and adopted OLS; then after adopting Hausman Test, the pseudo panel data was used to choose the most suitable model for regression estimates, analyzing and exploring whether the income of farm family in the Yunlin district was affected by the Sixth Naphtha Cracking Plant and the significant factors influencing the farm family income. Empirical results show that although the Sixth Naphtha Cracking Plant has no significant impact on the real income of farm family (including agricultural and non-agricultural incomes) in the district (Yunlin), it still provides considerable help in population employment and increased farm family income relatively higher than that in other districts; empirical results also show that by reduce unemployment rates and improve the education level of the farm family members (including future workers) so as to improve their income, while the human capital of other family members might also produce so-called “spillover effect” toward agricultural income.
