現在社會一切都存在交易，即一切即交易，特別是企業，企業的存在過程就是不同交易重合疊加的過程。也就是交易就是企業存在之根本，而從交易的歷史來看交易，才能弄清楚不同交易的發展史。本文通過交易即交易理論史，發現現代企業的交易是通過制度交易來實現權利自由，企業有了更大的權利自由，企業的存在度就會增長發展，企業的增長發展需要更大的權利自由，相互促進。那麼什麼企業制度交易，是如何影響企業的權利自由的。

本文研究制度交易對企業權利自由，就是通過交易的理論及交易經驗發展歷史過程，推出現代企業權利自由是靠企業的制度交易實現的，而交易的第一個階段，交易由最初的物的交換，其交換的目的主要就是相互彌補交易各方自身缺失的物的使用價值；交易的第二個階段、商品的交換，交換的是商品本身的價值，以商品的使用價值為輔；交易的第三階段，交易的是契約，契約交易的是權利的價值和使用價值，權利成為交易的核心；交易的第四個階段，交易的是制度，制度交易的是權利和自由，這是制度交易的核心；第五個階段，交易的是權利自由，也就是企業通過權利自由的交易實現企業的存在。

通過文獻梳理，發現並推導出現代企業的交易企業的權利自由，已經不是傳統意義上的利益最大化或利潤最大化。同時對交易的概念進行了重新定義，定義交易的是在不可能性中實現可能性的過程。即實現某一權利自由價值在時空上享有或佔有度，而實施或採取限制、控制、排除不可能性，補缺、遞增、增加可能性的行為意識的過程。本文通過企業環境訴訟案例分析並發現要實現的制度交易都是解決制度交易的安全性、確定性、穩定性、完全性的前提下完成的交易。

本文研究還發現，交易的函數公式，即假定制度交易只有A大於0,的前提下才可能實現交易，而A等於小於0都是不可能實現交易的。

本文主要是研究制度交易會對權利自由產生什麼影響，如果制度交易，其影響就是決定企業是否存在的可能性，即沒有制度交易就沒有企業的存在和發展。

本文對制度交易的研究，是通過我國近五年來的環境訴訟3322個真實案例的資料分析，研究企業制度交易對企業權利自由的影響程度。

本文雖然是從環境訴訟資料分析，分析環境訴訟中制度交易，而環境民事訴訟過程就是制度交易的過程研究的各項制度交易程度，發現制度交易度很低，交易量也是很低，也就是從環境訴訟中制度交易看制度交易度是不夠的，這會嚴重影響企業的權利自由，嚴重影響企業的存在發展。

本文研究發現制度交易直接影響企業的權利自由，只有制度交易享有更多更大的權利自由，企業才會實現更高的存在度生存度。即制度交易決定了企業的權利自由，企業的權利自由決定了企業的存在。

In today's society, transactions are ubiquitous, especially for enterprises. The existence process of enterprises is the process of superposition of different transactions. In other words, transaction holds key to the existence of enterprises. Through the lens of transaction history, we can gain a better understanding about how different transactions have developed. Through the transaction theory history, it is found that the transaction of modern enterprise realizes the right freedom through the institutional transaction. As enterprises gain greater right freedom, their presence grows and develops. Therefore, the growth of enterprises cannot be separated from greater right freedom and mutual promotion. So what is the institutional transaction of enterprises and how does it affect the right freedom of enterprises.

This paper studied the influence of institutional transactions on the right freedom of enterprises. To be specific, through the development of transaction theory and experience, it can be concluded that the right freedom of modern enterprises is realized by institutional transactions of enterprises. The first stage of a transaction is the initial exchange of goods, the purpose of which is mainly to make up for each other's lack of the use value of the goods; the second stage of the transaction is mainly the exchange of goods, in which the value of the goods is exchanged, supplemented by the use value of the goods; the third stage of the transaction is the contract transaction, in which the value and use value of rights are exchanged. In this stage, rights become the core of the transaction; the fourth stage of transaction is the institutional transaction, which is the exchange of rights and freedoms and the core of institutional transaction; the last stage of transaction is the transaction of right freedom, in other words, enterprises realize their existence through right freedom transaction.

Through literature review, the author found and deduced that the transaction of modern enterprises is mainly the transaction of right freedom of enterprises, which is no longer the benefit maximization or profit maximization in the traditional sense. At the same time, this paper redefined the concept of transaction, which is the process of realizing possibility in impossibility. That is, the process of realizing the possession degree of a certain right freedom value in time and space, and implementing or adopting the behavioral consciousness of restricting, controlling, eliminating the impossibility, filling the deficiency, increasing and increasing the possibility. Through the analysis of environmental litigation cases of the enterprises, this paper found that institutional transactions to be realized are completed under the premise of solving the security, certainty, stability and completeness of institutional transactions.

In addition, the function formula of the transaction was also found in this paper, that is, the assumed institutional transaction can only be realized on the premise when A is greater than 0, while the transaction cannot be realized when A is equal or less than 0.

This paper mainly studied the influence of institutional transactions on the right freedom, concluding that the institutional transactions determine the existence of enterprises, that is, there is no existence and development of enterprises without institutional transactions.

Through the data analysis of 3322 real cases related to environmental litigation in China in recent five years, this paper studied the degree of influence of institutional transactions on right freedom of enterprises.

This paper analyzed institutional transactions from the data of environmental litigation, and studied the degree of various institutional transactions. It was found that the degree of institutional transactions and the volume of transaction were very low. In other words, it is not enough to analyze the degree of institutional transactions from the perspective of environmental litigation, which will greatly affect the right freedom and existence and development of enterprises.

Through this study, it was found that institutional transactions directly affect the right freedom of enterprises. Only when institutional transactions enjoy more and greater right freedom, enterprises will realize a higher degree of existence. That is, institutional transactions determine the right freedom of enterprises, and the right freedom of enterprises determine the existence of enterprises.
