摘要

南非的农业部门尽管面临高失业率,但因创造就业机会而得到认可。然而,令人担忧的是,农业部门采用技术密集型方法并不一定能增加就业。本研究旨在利用时间序列分析法,分析南非农业产出与就业之间错综复杂的关系。本研究采用向量自回归(VAR)模型来评估南非农业产量与农业就业率之间的联系,时间跨度为 1990 年至 2022 年。研究结果表明,采用 ADF 检验时,两个变量都通过了水平检验,并在一阶差分处实现了静止,采用 Johansen 协整检验时,观察到了变量之间的长期均衡关系。在短期内,农业生产与农业就业率之间存在显著的正相关关系,ECT 系数为 0.139。格兰杰因果检验结果表明,农业就业格兰杰引起农业生产的单向关系,表明农业就业可用于预测农业生产的增长。研究建议,应优先考虑促进注入资金以提高农业部门生产的政策,以保持和改善就业机会。

Agricultural Production and Agricultural Employment Rate in South Africa: Time Series Analysis Approach
South Africa's agricultural sector, despite facing high unemployment, is acknowledged for creating job opportunities. However, there is concern that the sector's adoption of technology-intensive methods may not necessarily lead to increased employment. The study aims to analyze the intricate relationship between agricultural output and employment in South Africa using time series analysis. This research employed a Vector Autoregressive (VAR) model to evaluate the link between agricultural production and the rate of agricultural employment in South Africa spanning from 1990 to 2022. The findings indicate that both variables passed levels and became stationarity at the first difference when employing ADF, and a long-term equilibrium relationship between the variables was observed using Johansen cointegration test. Over the short term, there was a significant positive correlation among agricultural production and the agricultural employment rate evidenced from ECT coefficient of 0.139 value. The results of the Granger causality tests indicated unidirectional relationship that agricultural employment Granger-causes agricultural production, signifying that agricultural employment can be used to predict the growth of agricultural production. Study recommended that policies which promote injection of funds to improve production in the agriculture sector needs to be prioritized to maintain and improve employment opportunities.
