The invention provides a novel combination panel furniture having a connecting structure. The novel combination panel furniture comprises a main frame, wherein the main frame comprises a plurality of frame plate parts; the left end part and the right end part of each frame plate part are combined with the left end part and right end part of the adjacent frame plate part through square strip parts; according to observation from front view direction, the combined part of each square strip part and the left end part and right end part of the corresponding frame plate part takes on the look shown in the description; the frame plate parts have the same thickness; the cross section of each square strip part is square; and the side length of the square is as same as the thickness of the frame plate part. The frame plate part designed according to an AK-H formula has an increasing relationship and is completely universal. The novel combination of panel furniture and the connecting structure thereof break through the combined structure technology using side plates as skeleton, do not have role classification of side plates, laminates and the like in the combination, and solve the contradiction between diversity and humanity as well as standardization and universalization. Infinite variation of combination is realized by utilizing limited basic parts. DIY of products is realized.
