全面抗戰期間,中國共產黨領導人民予日軍以沉重打擊,日軍將其看作"真正敵人"。日方從中國共產黨與蘇聯的關系、國共合作的前途以及中國共產黨在華北抗日活動等角度對中國共產黨及其軍隊的政策、組織和黨員進行了廣泛調查。但是由于日軍傳統的"作戰第一主義"以及其對情報缺乏綜合的戰略分析,特別是由于日本軍部為強力推行侵華而選擇性使用情報,導致日方雖然發現了中國共產黨的真正實力及其政治工作的威力,也預測到中國共產黨領導的抗日斗爭將會進一步促進中國社會的發展,但是作為外來侵略者,其認識存在嚴重短板,沒有認識到抗日戰爭時期的中國共產黨已經更加成熟,日軍建立統治秩序的計劃不符合華北農村實際,特別是沒有看到近代以來中國人思想觀念的進步。盡管日本進行了大量情報調查并提出諸多對策,但終究未能挽回其失敗命運。

In the all-out War of Resistance against the Japanese Aggression,the Communist Party of China( CPC) led the Chinese people to fight against the Japanese army,so the Japanese regarded the CPC as their "real enemies. " The Japanese investigated the CPC and their armies on a wide scale regarding the relationship between the CPC and the Soviet Union,the future of the United Front,the anti-Japanese activities of the CPC in North China and so on. However,the Japanese army had the tradition of "Military First,"so they lacked the systematic strategic analysis of information. In particular,the Japanese army selectively used information in order to invade China with force. Therefore,although they discovered the power of the CPC and their political work,and predicted the anti-Japanese fighting led by the CPC would accelerate the development of the Chinese society,the Japanese army as invaders did not understand the CPC and the Chinese society sufficiently,nor realized that the CPC had become more mature during the War of Resistance. The plan of the Japanese army to establish a regime in North China was not suitable for the local reality and incompatible with the progress of the Chinese thought in the modern time. The Japanese army gathered a large amount of information and proposed various reactions to the CPC,but they were doomed to failure.
