摘要: 综合考虑石油勘探投资的不可逆性、序列性和不确定性,结合市场需求和勘探储量的不确定性刻画勘探储量转让价格的随机动态变化,运用实物期权思想下的序列投资决策方法探究了石油勘探项目的最优投资时机选择问题,得出各阶段最优投资时机临界值的解析表达式,并与一次性完成投资的决策结果进行对比,进而剖析了不确定性参数对各阶段最优投资时机的影响。结果表明,序列投资决策模型能够弥补一次性投资决策模型容易错失投资机会的局限性;各阶段最优投资时机临界值同市场需求波动率、勘探主体价格控制能力呈同向变动,同市场需求漂移率呈反向变动;随勘探进程的不断深入,最优勘探投资时机临界值对以上参数的敏感性程度不断增强。

Abstract: The traditional method to solve the investment decision of petroleum exploration projects is cash flow discount method. However, such methods ignore the importance of the irreversibility, uncertainty and the interaction between timing and quality, which may lead to short-sighted investment or poor decision-making. Considering the irreversibility, stages and uncertainties of petroleum exploration investments, combining the uncertainty of market demand and exploration reserves, the stochastic dynamic change of the transfer price of exploration reserves is obtained. Based on the sequential investment decision method, the optimal investment timing of petroleum exploration is derived, and the critical values of analytical solutions to the optimal investment timing are obtained. In addition, they are compared with the one-time investment decision-making results, and the influences of uncertainty parameters on optimal investment timing are discussed. The main contributions are as follows. (1)The critical values of the optimal investment timing for each stage of the oil exploration sequential investments are mainly due to such uncertainties as risk-free interest rates, unit exploration cost, market volatility, market drift rates, the prospectors' ability to control over the transfer price of exploration reserves, and the additional exploration reserves at each stage.(2)Sequential investment decision model can make up for the shortcomings of one-time investment which is easy to miss the investment opportunities.(3)The optimal investment timing is positively correlated with the fluctuation of market volatility and prospectors' ability to control over the transfer price of exploration reserves, and negatively correlated with the market drift rates. (4)With the development of the exploration process, the sensitivity of the optimal exploration investment timing to the parameters above is increasing. This paper can enrich and expand the application of real options theory in the investment decision-making of petroleum resource exploration projects, and provide some theoretical basis and decision-making reference for the optimal timing of the sequential investment of exploration.

Key words: petroleum exploration projects, sequential investment, the transfer price of exploration reserves, optimal investment timing, real options
