Let{xn,n≥0}be a Markov chain with a countable state space S and let f(·)be a measurable function from S to R and consider the functionals of the Markov chain yn:=f(xn).We construct a new type of self-normalized sums based on the random-block scheme and establish a Crame′r-type moderate deviations for self-normalized sums of functionals of the Markov chain.

政府可持续投入老旧小区改造资金有限,居民对自主更新呼声渐长。当前城市更新制度对自主更新定位模糊,已成为制约更新项目推进的重要因素。基于国内案例研究发现,主体权责不清是当前自主更新的困境之一,其本质是对更新改造权利界定不足引起的。探讨建设开发权和规划编制权的内涵、赋权对象、具体形态和效力,参照英国和日本居民自主更新的制度经验,提出通过法律或政策明确自主更新权利主体和组织实施主体的相关权益;规划制度上明晰各类更新改造规划(计划)与法定规划和规划许可的关系;建议政府针对不同类型老旧小区因地施策,激励社会资本投入,调动居民和社会资本的参与积极性。
