行政訴訟中律師代理影響因素與效果的實證考察

律師參與是行政訴訟制度目的實現的重要支點。通過特定範圍裁判資料的定量研究發現，我國行政訴訟律師代理率的局部差異比較顯著。經濟能力、權力壓力、維權意識、權利類型等影響因素的二元回歸分析顯示，各地的律師參與水準受到市場供需和法治環境等因素不同程度的影響，存在一個原告律師代理率的“區域閾值”。律師代理的實效性分析表明，律師的專業服務總體上對行政訴訟制度運行產生了積極作用。基於上述局部差異、影響因素與實效性考察，可提出“黏合功能”理論作為解釋，即行政訴訟中的律師代理實際上有助於行政訴訟制度各項目的均衡實現。為提高行政爭議解決的法治化水準，有必要強化行政訴訟法律援助和政府公職律師的內外部政策激勵，進一步改善行政訴訟律師參與的供需狀況。

The participation of attorneys is an important fulcrum for the realization of the purpose of the administrative litigation system. Through the quantitative study of adjudication data within a specific scope, it is found that the difference of the proportion of attorneys representing in administrative litigation between local areas is obvious. Based on the binary regression analysis of influencing factors such as economic ability, power pressure, awareness of rights protection and rights type, it shows that the participation level of attorneys in various regions is affected by factors such as market supply and demand and the legal environment to varying degrees. There is a’regional threshold’for the attorney representation rate for the plaintiff. The analysis of the effectiveness of attorney’ representation shows that attorney’s professional services have improved the operation of the administrative litigation system. Based on the above-mentioned regional differences, influencing factors and practical effects, the study proposes the theory of’bonding function’as an explanation, which is that attorney representation in administrative litigation is actually beneficial to the balanced realization of various purposes of the administrative litigation system. In order to improve the legalization level of administrative dispute resolution, it is necessary to strengthen the legal aid for administrative litigation and the internal and external policy incentives for government attorneys, and further improve the supply and demand of the participation of administrative litigation attorneys.
