本文使用标准时间序列计量经济学实证检验了研发和气候变化对西澳大利亚农业部门的影响。基于1977-2005年的历史数据，实证结果表明，R&D和气候变化对长期生产率增长都有影响。全要素生产率对R&D支出的长期弹性为0.497，而气候变化的长期弹性为0.506。无论从短期还是长期来看，研发支出与全要素生产率增长都存在单向因果关系。此外，方差分解和脉冲响应函数证实，在样本期之后，很大一部分产出和生产率增长是由R&D支出解释的。这些结果证明，在农业部门气候条件不断恶化的情况下增加研发投资，以改善生产率增长的长期前景是合理的。
This article empirically examines the impact of R&D and climate change on the Western Australian Agricultural sector using standard time series econometrics. Based on historical data for the period of 1977–2005, the empirical results show that both R&D and climate change matter for long-run productivity growth. The long-run elasticity of total factor productivity (TFP) with respect to R&D expenditure is 0.497, while that of climate change is 0.506. There is a unidirectional causality running from R&D expenditure to TFP growth in both the short run and long run. Further, the variance decomposition and impulse response function confirm that a significant portion of output and productivity growth beyond the sample period is explained by R&D expenditure. These results justify the increase in R&D investment in the deteriorating climatic condition in the agricultural sector to improve the long-run prospects of productivity growth.
