中文摘要：

初次收入分配结构调整是指调整国民收入在各项目之间的分配比例，是国民经济体系中的重要内容。文章对投入产出模型进行扩展，深入透析投资倾向的变动对初次收入分配中各项目的影响，以及对初次收入分配结构的调整作用。研究表明，投资倾向对初次收入分配的影响与各产业的项目系数、生产直接消耗系数，以及国内收入总额密切相关；在现有的要素价格和投资结构情况下，提高投资倾向会使国民收入中劳动报酬、生产税净额的比例降低，会使固定资产折旧和营业盈余的比例提高。

英文摘要：

Primary income distribution structure refers to the ratio adjustment of incomes between the various projects, which is an important part of national economic system. Based on the input-output theory, the effect of propensity to investment on primary income distribution structure can be analyzed. According to the study, the propensity to investment influence the primary income distribution structure, closely related to the various industries and project coefficient, the production of direct consumption coefficient, and the total domestic revenues. Within the existing structure of factor prices and investment structure, the propensity to investment would reduce the proportion of labor compensation and net taxes in national income, but raise the proportion of depreciation of fixed assets and improve the operating earnings.
