本文通过多种反事实方法分析，发现1928年后苏联经济增长的证据支持有条件的增长溢价，但未确定斯大林是唯一制度上可行的路径。
AI 中文摘要
本文评估1928年后俄罗斯及苏联经济异常快速的增长是否需要特定的斯大林主义解释。该分析将这一历史问题视为一系列要求日益提高的反事实比较，而非观测到的增长与单一替代方案的二元比较。研究结合了全球宏观数据库与麦迪森项目的长期产出序列，并运用了合成控制法、增强合成控制法、合成双重差分法、交互式因子模型、矩阵补全、预测基准、历史类比、空间及时间安慰剂、捐赠池扰动、端点敏感性分析以及独立的苏联国民账户重建等方法。一项关键的方法论贡献是修正后的新经济政策反事实：该分析未外推1922至1928年观测到的快速复苏，而是将复苏缺口建模为锚定1914年前趋势的自举过程，并利用观测到的俄罗斯产出缺口的战后收窄进行校准。俄罗斯核心估计在每个端点均超过中位数可允许前沿，且自1930年代中期起超过主要第90百分位前沿；而更广泛的苏联领土总量则更为保守。捐赠扰动保留了俄罗斯核心的正向溢价，但有限的安慰剂样本、不完美的预处理拟合、与复苏相关的假阳性、来源依赖性以及不利的上限，均阻止了对历史必要性的强主张。证据支持有条件的增长溢价，但未确定斯大林是唯一在制度上可行的路径。
英文摘要
This article evaluates whether the exceptionally rapid growth of the Russian and Soviet economy after 1928 requires a specifically Stalinist explanation. The analysis treats this historical question as a sequence of increasingly demanding counterfactual comparisons rather than a binary comparison between observed growth and a single alternative. Long run output series from the Global Macro Database and the Maddison Project are combined with synthetic control, augmented synthetic control, synthetic difference in differences, interactive factor models, matrix completion, prediction benchmarks, historical analogues, spatial and temporal placebos, donor pool perturbations, endpoint sensitivity, and independent Soviet national account reconstructions. A key methodological contribution is a revised New Economic Policy counterfactual. Instead of extrapolating the rapid recovery observed from 1922 to 1928, the analysis models the recovery gap as a bootstrap process anchored to the pre 1914 trend and calibrated using the observed postwar closure of the Russian output gap. The Russian core estimates exceed the median admissible frontier at every endpoint and surpass the main 90th percentile frontier from the mid 1930s onward, whereas the broader Soviet territorial aggregate remains more conservative. Donor perturbations preserve a positive Russian core premium, but the limited placebo sample, imperfect pretreatment fit, recovery related false positives, source dependence, and hostile upper bounds prevent strong claims of historical necessity. The evidence supports a conditional growth premium but does not identify Stalin as the only institutionally feasible path.
