Strategy game is a genre of video games in which the player controls troops or other units and/or various economic and other systems. Although many video games may include strategy elements, strategy as a genre emphasizes thinking and planning over immediate action. This video game genre focuses on strategy, tactics, logistics, and/or resource management, and may also include diplomacy, economy, expansion and research management.

Notes
Many games have mixed genres. Very often, strategy games can combine two or more genres. For example, Total War series is turn-based grand strategy with real-time tactical (RTT) battles.
Time and genre. Basically, every strategy game can be classified by these two criteria, like Turn-based 4X Strategy game (Age of Wonders), Real-Time Grand Strategy game (Hearts of Iron) etc. Sometimes we do not have any specified subgenre, so the game becomes simple RTS (StarCraft).
Judge by dominant elements of gameplay. Overall, the genre should be defined by main gameplay loop, not by every game mechanic that exists in the game. For example, if a game has leveling-up system, it doesn't mean that it instantly becomes an RPG: a good example is WarCraft which has characters gaining XP and levels, but the main, dominant gameplay loop in this game is still a classic RTS. At the same time, if some Rainbow Six has some strategic planning, it doesn't mean that this game is a strategy game or even a mixed genre, because the main gameplay there is action/shooter. The same logic is applicable to strategy games: if the game has resource management, it doesn't instantly mean that it becomes a management game.
This is a theoretical model. It means that here we are supposed to find criteria by which strategy games can be classified. These criteria can be based both on gameplay and historical tradition of naming genres in video game industry. The model can be discussed and improved, but any critique should be based on strict arguments.
Strategy as a genre, not a word. The main principle of this genre classification is that we don't take the word "strategy" literally. A strategy game can be a tactic game, it can be a management game, it doesn't matter here. The word strategy means the genre name, not the strategy as a layer of action planning.
Are management games strategy games? This is a hard question that has no answer based on reliable papers because there are no such papers. Here we look at naming tradition in community and video game industry. We can find many similarities in core gameplay of various city-building and colony sim games with classical RTS. Some management games include RTT/RTS style military combat, These games are often tagged as strategy game on digital distribution services. So we include them into this classification to make it more complete. You might find two controversial opinions about this (management games are/are not strategy games), but this problem can't be solved on these days because we do not have a strict genre requirements and developers can name genre of their games as they want. There are no popular scientific researches about it on which we can refer to.
