工具（厂商） & 口碑亮点 & 主要吐槽 & 参考价格
TRAE（字节跳动）★ & 基础版永久免费且无调用次数限制；SOLO 模式从需求到部署全流程自主；中文原生；第三方评测代码生成准确率约 98% & 快照回退丢代码仍有新案例（2026-06 论坛）；普通对话模式上下文偏短 & 免费层 + Pro 30 元/月
Qoder（阿里）★ & IDC 口径 47.6% 份额居中国第一；Skill 生态丰富；先列 to-do 规划再执行；仓库 Wiki 自动文档；国内网络与支付友好 & Credits 消耗规律不完全透明，重度任务消耗快 & 个人版免费 + Pro 99 元/月
Cursor（Anysphere，SpaceX 换股收购中） & 全球体验标杆；并行 Agent 能力强；收购后补贴战（凭退订 Claude 凭证送 200 美元顶配） & Token 计费下复杂任务额度消耗快；国内访问需网络加速 & Pro $20/月（顶配 $200/月限时）
GitHub Copilot（微软） & 约 180 万付费用户、42% 全球份额；10 美元/月全场最低；插件化兼容所有主流 IDE & 「最普遍也最不被热爱」（社区权力榜最爱率约 9%）；6 月改 Credits 计费后额度易爆 & $10/月 + Business $19/月
Windsurf（Cognition） & 收购连续剧落幕后趋稳；2.0 版自研 SWE-1.5 模型、Codemaps、与 Devin 云端 Agent 打通 & 创始团队已随谷歌出走，品牌长期不确定性仍存 & 免费层 + Pro $15/月
Kiro（亚马逊 AWS） & Spec 驱动开发（EARS 需求语法）独树一帜，先文档后代码、工程可追溯；初创团队经 AWS Startups 可申请一年免费 Pro+ & 免费档每月仅 50 Credits，复杂任务几次用完 & 免费层 + Pro+ $20/月
CodeBuddy（腾讯） & IDE、插件、CLI 三形态齐全；99 元/年性价比突出；中文理解与腾讯云联动强 & IDC 口径国内份额约 7% 排第四；稳定性口碑分化 & 免费层 + 99 元/年\
★为本手册教学主力。价格为 2026 年 9 月各官网口径，促销活动以官网为准。完整 CLI 类工具口碑（H.3）、风险案例（H.4）见 GitHub 备份。
H.2 经济类专业学生选型建议（一段总结）
教学主线：TRAE + Qoder 双主力混用——前者零成本起步，后者 Skill 生态深化；两者都支持 MCP，本手册全部实操示例均通过此组合验证。
研究主线：VS Code + GitHub Copilot（或 Qoder Pro）——前者开源生态成熟，后者稳定且 $10/月成本可控；正式发表前用 Git 做频繁提交，AI 大改动前必先 commit。
避坑铁律：① 开启 Git 并频繁提交；② AI 改动务必人工 review 后再接受；③ 对删除/卸载类操作保持最高警惕；④ 涉密或对外交付的代码慎用会向输出注入水印的工具（Claude Code 2026-08 上线水印）。

L4|L4|L4|L4
Tool (vendor) & Reputation highlights & Main complaints & Reference price
TRAE (ByteDance) ★ & Basic tier permanently free with no call limits; SOLO mode runs the whole flow from requirement to deployment autonomously; native Chinese; third-party benchmarks put code-generation accuracy near 98% & Snapshot rollback still losing code (new cases on the 2026-06 forum); short context in ordinary chat mode & Free tier + Pro 30 yuan/month
Qoder (Alibaba) ★ & IDC-measured 47.6% share, first in China; rich Skill ecosystem; states a to-do plan before executing; automatic repository Wiki documentation; friendly network access and payment in mainland China & Credits consumption not fully transparent; heavy tasks burn credits quickly & Personal free tier + Pro 99 yuan/month
Cursor (Anysphere, being acquired by SpaceX in a share swap) & Global benchmark for experience; strong parallel-agent capability; post-acquisition subsidy war (200 USD top tier offered against proof of a cancelled Claude subscription) & Under token billing, complex tasks consume quota fast; access from mainland China needs network acceleration & Pro $20/month (top tier $200/month, limited time)
GitHub Copilot (Microsoft) & About 1.8 million paying users, 42% global share; 10 USD/month the lowest of all; plugin architecture compatible with every mainstream IDE & “Most widespread and least loved” (favourite rate about 9% on a community power ranking); credits billing since June makes the quota blow up easily & $10/month + Business $19/month
Windsurf (Cognition) & Stabilised after the acquisition saga; version 2.0 ships the in-house SWE-1.5 model, Codemaps, and integration with Devin cloud agents & Founding team has left for Google; long-run brand uncertainty remains & Free tier + Pro $15/month
Kiro (Amazon AWS) & Spec-driven development (EARS requirements syntax) unique in the field—documentation before code, engineering traceability; startups can apply for a year of free Pro+ through AWS Startups & Only 50 credits per month on the free tier; a few complex tasks exhaust it & Free tier + Pro+ $20/month
CodeBuddy (Tencent) & IDE, plugin, and CLI forms all present; 99 yuan/year outstanding value; strong Chinese comprehension and Tencent Cloud integration & About 7% domestic share by IDC, fourth place; stability reputation divided & Free tier + 99 yuan/year\
★ marks the teaching mainstays of this handbook. Prices follow each vendor’s official site as of September 2026; promotions are subject to those sites. The full reputation review of CLI-type tools (H.3) and risk cases (H.4) are in the GitHub backup.
H.2 Selection advice for economics students (one-paragraph summary)
Teaching track: mix TRAE and Qoder as the two mainstays—the former starts at zero cost, the latter deepens through its Skill ecosystem; both support MCP, and every hands-on example in this handbook was verified with this combination.
Research track: VS Code + GitHub Copilot (or Qoder Pro)—the former has a mature open-source ecosystem, the latter is stable at a controllable $10/month; commit frequently with Git before publication, and always commit before any large AI-driven change.
Iron rules for avoiding pitfalls: (1) enable Git and commit often; (2) review every AI change by hand before accepting it; (3) treat delete/uninstall operations with the highest suspicion; (4) for confidential or externally delivered code, be wary of tools that inject watermarks into output (Claude Code shipped watermarking in 2026-08).
