제I보에 이어, 석유화학공업 전반에 걸쳐 상세한 전망을 하였다. 또 최종수요부문의 일정액증가에 따르는 석유화학품의 유발생성량을 계산하였고 영향력계수를 계산하여 도시함으로써, 각 산업이 전체경제에서 어떠한 역할을 하는가를 구체적으로 제시하였다. 총론으로 에틸렌, 프로필렌, 부타디엔, 벤젠, 크실렌 등의 기본원료가 되는 석유화학품에 대해서는, 물질 흐름표를 작성함으로써 원료와 제품간의 수급관계를 명백히하였다.

Following the report Part I^*, a detailed discussion of the output of petrochemical products was carried on. The induced production of petrochemical products, caused by an incremental final demand, was presented and discussed. The sensitivity coefficient versus influence coefficient plots were also presented to establish the correlation between any specific sector and the rest of the sectors, whereby the role of petrochemical products in the whole national economy could be derived. In summary, the material flow diagrams for the basic starting materials, such as ethylene, propylene, butadiene, benzene, and xylenes were presented for the years of 1970, 1974, 1978, and 1982.
