迈向 充满 希望 的 新 世纪 —— 一九九八年 新年 讲话 ( 附 图片 1 张 ) | |||
中共中央 总书记 、 国家 主席 江 泽民 | |||
( 一九九七年 十二月 三十一日 ) | |||
12月 31日 , 中共中央 总书记 、 国家 主席 江 泽民 发表 1998年 新年 讲话 《 迈向 充满 希望 的 新 世纪 》 。 ( 新华社 记者 兰 红光 摄 ) | |||
同胞 们 、 朋友 们 、 女士 们 、 先生 们 : | |||
在 1998年 来临 之际 , 我 十分 高兴 地 通过 中央 人民 广播 电台 、 中国 国际 广播 电台 和 中央 电视台 , 向 全国 各族 人民 , 向 香港 特别 行政区 同胞 、 澳门 和 台湾 同胞 、 海外 侨胞 , 向 世界 各国 的 朋友 们 , 致以 诚挚 的 问候 和 良好 的 祝愿 ! | |||
1997年 , 是 中国 发展 历史 上 非常 重要 的 很 不 平凡 的 一 年 。 中国 人民 决心 继承 邓 小平 同志 的 遗志 , 继续 把 建设 有 中国 特色 社会主义 事业 推向 前进 。 中国 政府 顺利 恢复 对 香港 行使 主权 , 并 按照 “ 一国两制 ” 、 “ 港人治港 ” 、 高度 自治 的 方针 保持 香港 的 繁荣 稳定 。 中国 共产党 成功 地 召开 了 第十五 次 全国 代表大会 , 高举 邓小平理论 伟大 旗帜 , 总结 百年 历史 , 展望 新 的 世纪 , 制定 了 中国 跨 世纪 发展 的 行动 纲领 。 | |||
在 这 一 年 中 , 中国 的 改革 开放 和 现代化 建设 继续 向前 迈进 。 国民经济 保持 了 “ 高 增长 、 低 通胀 ” 的 良好 发展 态势 。 农业 生产 再次 获得 好 的 收成 , 企业 改革 继续 深化 , 人民 生活 进一步 改善 。 对外 经济 技术 合作 与 交流 不断 扩大 。 民主 法制 建设 、 精神文明 建设 和 其他 各项 事业 都 有 新 的 进展 。 我们 十分 关注 最近 一个 时期 一些 国家 和 地区 发生 的 金融 风波 , 我们 相信 通过 这些 国家 和 地区 的 努力 以及 有关 的 国际 合作 , 情况 会 逐步 得到 缓解 。 总的来说 , 中国 改革 和 发展 的 全局 继续 保持 了 稳定 。 | |||
在 这 一 年 中 , 中国 的 外交 工作 取得 了 重要 成果 。 通过 高层 互访 , 中国 与 美国 、 俄罗斯 、 法国 、 日本 等 大国 确定 了 双方 关系 未来 发展 的 目标 和 指导 方针 。 中国 与 周边 国家 和 广大 发展中国家 的 友好 合作 进一步 加强 。 中国 积极 参与 亚太经合 组织 的 活动 , 参加 了 东盟 — 中 日 韩 和 中国 — 东盟 首脑 非正式 会晤 。 这些 外交 活动 , 符合 和平 与 发展 的 时代 主题 , 顺应 世界 走向 多极化 的 趋势 , 对于 促进 国际 社会 的 友好 合作 和 共同 发展 作出 了 积极 的 贡献 。 | |||
1998年 , 中国 人民 将 满怀信心 地 开创 新 的 业绩 。 尽管 我们 在 经济社会 发展 中 还 面临 不少 困难 , 但 我们 有 邓小平理论 的 指引 , 有 改革 开放 近 20 年 来 取得 的 伟大 成就 和 积累 的 丰富 经验 , 还有 其他 的 各种 有利 条件 , 我们 一定 能够 克服 这些 困难 , 继续 稳步前进 。 只要 我们 进一步 解放思想 , 实事求是 , 抓住 机遇 , 开拓进取 , 建设 有 中国 特色 社会主义 的 道路 就 会 越 走 越 宽广 。 | |||
实现 祖国 的 完全 统一 , 是 海内外 全体 中国 人 的 共同 心愿 。 通过 中 葡 双方 的 合作 和 努力 , 按照 “ 一国两制 ” 方针 和 澳门 《 基本法 》 , 1999年 12月 澳门 的 回归 一定 能够 顺利 实现 。 | |||
台湾 是 中国 领土 不可分割 的 一 部分 。 完成 祖国 统一 , 是 大势所趋 , 民心所向 。 任何 企图 制造 “ 两 个 中国 ” 、 “ 一中一台 ” 、 “ 台湾 独立 ” 的 图谋 , 都 注定 要 更 失败 。 希望 台湾 当局 以 民族 大义 为重 , 拿 出 诚意 , 采取 实际 的 行动 , 推动 两岸 经济 文化 交流 和 人员 往来 , 促进 两岸 直接 通邮 、 通航 、 通商 的 早日 实现 , 并 尽早 回应 我们 发出 的 在 一个 中国 的 原则 下 两岸 进行 谈判 的 郑重 呼吁 。 | |||
环顾 全球 , 日益 密切 的 世界 经济 联系 , 日新月异 的 科技 进步 , 正在 为 各国 经济 的 发展 提供 历史 机遇 。 但是 , 世界 还 不 安宁 。 南北 之间 的 贫富 差距 继续 扩大 ; 局部 冲突 时有发生 ; 不 公正 不 合理 的 旧 的 国际 政治经济 秩序 还 没有 根本 改变 ; 发展中国家 在 激烈 的 国际 经济 竞争 中 仍 处于 弱势 地位 ; 人类 的 生存 与 发展 还 面临 种种 威胁 和 挑战 。 和平 与 发展 的 前景 是 光明 的 , 21 世纪 将 是 充满 希望 的 世纪 。 但 前进 的 道路 不 会 也 不 可能 一帆风顺 , 关键 是 世界 各国 人民 要 进一步 团结 起来 , 共同 推动 早日 建立 公正 合理 的 国际 政治经济 新 秩序 。 | |||
中国 政府 将 继续 坚持 奉行 独立自主 的 和平 外交 政策 , 在 和平共处 五 项 原则 的 基础 上 努力 发展 同 世界 各国 的 友好 关系 。 中国 愿意 加强 同 联合国 和 其他 国际 组织 的 协调 , 促进 在 扩大 经贸 科技 交流 、 保护 环境 、 消除 贫困 、 打击 国际 犯罪 等 方面 的 国际 合作 。 中国 永远 是 维护 世界 和平 与 稳定 的 重要 力量 。 中国 人民 愿 与 世界 各国 人民 一道 , 为 开创 持久 和平 、 共同 发展 的 新 世纪 而 不懈努力 ! | |||
在 这 辞旧迎新 的 美好 时刻 , 我 祝 大家 新年 快乐 , 家庭 幸福 ! | |||
谢谢 ! ( 新华社 北京 12月 31日 电 ) | |||
在 十五大 精神 指引 下 胜利 前进 —— 元旦 献辞 | |||
我们 即将 以 丰收 的 喜悦 送 走 牛年 , 以 昂扬 的 斗志 迎来 虎年 。 我们 伟大 祖国 在 新 的 一 年 , 将 是 充满 生机 、 充满 希望 的 一 年 。 | |||
刚刚 过去 的 一 年 , 大气磅礴 , 波澜壮阔 。 在 这 一 年 , 以 江 泽民 同志 为 核心 的 党中央 , 继承 邓 小平 同志 的 遗志 , 高举 邓小平理论 的 伟大 旗帜 , 领导 全党 和 全国 各族 人民 坚定不移 地 沿着 建设 有 中国 特色 社会主义 道路 阔步 前进 , 写 下 了 改革 开放 和 社会主义 现代化 建设 的 辉煌 篇章 。 顺利 地 恢复 对 香港 行使 主权 , 胜利 地 召开 党 的 第十五 次 全国 代表大会 ——— 两 件 大事 办 得 圆满 成功 。 国民经济 稳中求进 , 国家 经济 实力 进一步 增强 , 人民 生活 继续 改善 , 对外 经济 技术 交流 日益 扩大 。 在 国际 金融 危机 的 风浪 波及 许多 国家 的 情况 下 , 我国 保持 了 金融 形势 和 整个 经济 形势 的 稳定 发展 。 社会主义 精神文明 建设 和 民主 法制 建设 取得 新 的 成绩 , 各项 社会 事业 全面 进步 。 外交 工作 取得 可喜 的 突破 , 我国 的 国际 地位 和 国际 威望 进一步 提高 。 实践 使 亿万 人民 对 邓小平理论 更加 信仰 , 对 以 江 泽民 同志 为 核心 的 党中央 更加 信赖 , 对 伟大 祖国 的 光辉 前景 更加 充满 信心 。 | |||
1998年 , 是 全面 贯彻 落实 党 的 十五大 提 出 的 任务 的 第一 年 , 各 条 战线 改革 和 发展 的 任务 都 十分 繁重 , 有 许多 深 层次 的 矛盾 和 问题 有待 克服 和 解决 , 特别 是 国有 企业 改革 已经 进入 攻坚 阶段 。 我们 必须 进一步 深入 学习 和 掌握 党 的 十五大 精神 , 统揽全局 , 精心 部署 , 狠抓 落实 , 团结 一致 , 艰苦奋斗 , 开拓 前进 , 为 夺取 今年 改革 开放 和 社会主义 现代化 建设 的 新 胜利 而 奋斗 。 | |||
今年 是 党 的 十一 届 三中全会 召开 20 周年 , 是 我们 党 和 国家 实现 伟大 的 历史 转折 、 进入 改革 开放 历史 新 时期 的 20 周年 。 在 新 的 一 年 里 , 大力 发扬 十一 届 三中全会 以来 我们 党 所 恢复 的 优良 传统 和 在 新 的 历史 条件 下 形成 的 优良 作风 , 对于 完成 好 今年 的 各项 任务 具有 十分 重要 的 意义 。 | |||
我们 要 更 好 地 坚持 解放思想 、 实事求是 的 思想 路线 。 解放思想 、 实事求是 , 是 邓小平理论 的 精髓 。 实践 证明 , 只有 解放思想 、 实事求是 , 才 能 冲破 各种 不 切合 实际 的 或者 过时 的 观念 的 束缚 , 真正 做到 尊重 、 认识 和 掌握 客观 规律 , 勇于 突破 , 勇于 创新 , 不断 开创 社会主义 现代化 建设 的 新 局面 。 党 的 十五大 是 我们 党 解放思想 、 实事求是 的 新 的 里程碑 。 进一步 认真 学习 和 掌握 十五大 精神 , 解放思想 、 实事求是 , 我们 的 各项 事业 就 能 结 出 更加 丰硕 的 成果 。 | |||
我们 要 更 好 地 坚持 以 经济 建设 为 中心 。 各项 工作 必须 以 经济 建设 为 中心 , 是 邓小平理论 的 基本 观点 , 是 党 的 基本 路线 的 核心 内容 , 近 20 年 来 的 实践 证明 , 坚持 这个 中心 , 是 完全 正确 的 。 今后 , 我们 能否 把 建设 有 中国 特色 社会主义 伟大 事业 全面 推向 21 世纪 , 关键 仍然 要 看 能否 把 经济 工作 搞 上去 。 各级 领导 干部 要 切实 把 精力 集中 到 贯彻 落实 好 中央 关于 今年 经济 工作 的 总体 要求 和 各项 重要 任务 上 来 , 不断 提高 领导 经济 建设 的 能力 和 水平 。 | |||
我们 要 更 好 地 坚持 “ 两手抓 、 两手 都 要 硬 ” 的 方针 。 在 坚持 以 经济 建设 为 中心 的 同时 , 积极 推进 社会主义 精神文明 建设 和 民主 法制 建设 , 是 建设 富强 、 民主 、 文明 的 社会主义 现代化 国家 的 重要 内容 。 实践 证明 , 经济 建设 的 顺利 进行 , 离 不 开 精神文明 建设 和 民主 法制 建设 的 保证 。 党 的 十五大 依据 邓小平理论 和 党 的 基本 路线 提 出 的 党 在 社会主义 初级阶段 经济 、 政治 、 文化 的 基本 纲领 , 为 “ 两手抓 、 两手 都 要 硬 ” 提供 了 新 的 理论 根据 , 提 出 了 更 高 要求 , 现在 的 关键 是 认真 抓好 落实 。 | |||
我们 要 更 好 地 发扬 求真务实 、 密切 联系 群众 的 作风 。 这 是 把 党 的 方针 、 政策 落到实处 , 使 改革 和 建设 取得 胜利 的 重要 保证 。 在 当前 改革 进一步 深化 , 经济 不断 发展 , 同时 又 出现 一些 新 情况 、 新 问题 和 新 困难 的 形势 下 , 更 要 发扬 这样 的 好 作风 。 要 尊重 群众 的 意愿 , 重视 群众 的 首创 精神 , 关心 群众 的 生活 疾苦 。 江 泽民 同志 最近 强调 指出 , 要 大力 倡导 说实话 、 办 实事 、 鼓 实劲 、 讲 实效 的 作风 , 坚决 制止 追求 表面文章 , 搞 花架子 等 形式主义 , 坚决 杜绝 脱离 群众 、 脱离 实际 、 浮躁 虚夸 等 官僚主义 。 这 是 非常 重要 的 。 因此 , 各级 领导 干部 务必 牢记 全心全意 为 人民 服务 的 宗旨 , 在 勤政廉政 、 艰苦奋斗 方面 以身作则 , 当 好 表率 。 | |||
1998 , 瞩目 中华 。 新 的 机遇 和 挑战 , 催 人 进取 ; 新 的 目标 和 征途 , 催 人 奋发 。 英雄 的 中国 人民 在 以 江 泽民 同志 为 核心 的 党中央 坚强 领导 和 党 的 十五大 精神 指引 下 , 更 高 地 举起 邓小平理论 的 伟大 旗帜 , 团结 一致 , 扎实 工作 , 奋勇前进 , 一定 能够 创造 出 更加 辉煌 的 业绩 ! | |||
