又有大股东因违规减持被处罚。管理层可以考虑用技术手段直接"锁定"大股东持股，符合条件后解锁相 应数量，从技术上杜绝违规减持，用科技来防范资本违规。 5月23日晚间，证监会官网披露的一则行政处罚决定书显示，田汉、京汉控股集团有限公司、建水泰融 企业管理有限公司等因违反限制性规定转让股票、信息披露违法行为被证监会罚没近2.3亿元。 违规减持不仅损害了中小投资者的利益，更扰乱了市场的正常秩序，侵蚀着资本市场的公信力。在此背 景下，本栏建议管理层运用技术手段直接"锁定"大股东持股，以从技术层面杜绝违规减持，或许将为资 本市场监管带来新的思路。 违规减持乱象偶有发生，根源在于违规成本与收益的严重失衡。对于一些大股东而言，违规减持所带来 的巨额利益诱惑，远超可能面临的处罚成本。这种不对等使得部分大股东心存侥幸，不惜铤而走险。传 统的监管方式，虽在一定程度上能够起到威慑作用，但往往依赖于事后的调查与惩处，存在一定的滞后 性，难以在违规行为发生的第一时间进行有效遏制。而技术手段的引入，则能够弥补这一监管短板，实 现从事后追责到事前预防的转变。 通过技术手段"锁定"大股东持股，并依据减持条件解锁相应数量，这一方法具有显著优势。 ...

Core Viewpoint - The recent increase in terminated share transfer agreements among listed companies highlights a dual nature in the market, where some companies continue to pursue strategic investments while others face regulatory scrutiny and market conditions that hinder transactions [2][5][6]. Group 1: Market Dynamics - In May, 13 listed companies announced the termination of share transfer agreements, a significant increase compared to previous months, which typically saw only three to five cases [5]. - The reasons for termination often include incomplete procedures and market conditions where previously set transfer prices are now below current market values [5][6]. - Despite the rise in terminations, there are still ongoing agreements aimed at introducing strategic investors or changing actual controllers, indicating that the market remains active [7][8]. Group 2: Regulatory Environment - The tightening of regulations following the introduction of new reduction rules has led to increased scrutiny of share transfer agreements, with calls for clearer prohibitions on certain behaviors to prevent gray operations [3][9]. - The market is seeing a trend where parties involved in agreements are extending lock-up periods to enhance compliance and reduce the risk of speculative trading [10][11]. Group 3: Strategic Implications - Protocol transfers serve as an effective tool for major shareholders to meet liquidity needs while avoiding direct impacts on stock prices from secondary market sales [6][8]. - The presence of financial investors as transferees is becoming more challenging, but agreements aimed at strategic partnerships continue to progress normally [8]. - The market's dual characteristics suggest a need for balance between resource allocation functions and risk prevention in the context of share transfers [3][10].
