Semi‐parametric Modelling of Investments in Heating Installations: The Case of the Dutch Glasshouse Industry
用半参数方法估计供暖设施投资模型，发现边际成本在小投资时快速上升、大投资时增速放缓，且投资对能源价格高度敏感，表明能源税可有效促进节能供暖设施投资。
Abstract This paper applies a semi‐parametric approach to estimating a generalised model of investments in heating installations. The results suggest that marginal costs of investments in heating installations increase quickly at small investment levels, whereas the increase slows down at higher investment levels. Therefore, standard parametric adjustment cost models are probably biased such that they underestimate the costs of small investments and overestimate the costs of large investments. Results also show that investments in heating installations are very responsive to changes in energy prices. Therefore, an energy tax may be an effective instrument to encourage investments in new energy‐saving heating installations.
