日本的小麦生产在世界上所占比重很小。1984年,该国小麦种植面积23.2万公顷,单产3.2吨/公顷(合每亩213.3公斤),总产量75万吨。全部供应国内市场,自给率为12%,尚需进口小麦500万吨。虽然如此,日本的小麦研究却很有成就,在很多方面居于世界领先地位,包括小麦遗传学、细胞学、生物工程(主要是染色体工作)以及种质研
Japan’s wheat production accounts for a very small part of the world. In 1984, the country’s wheat acreage was 232,000 hectares with a yield of 3.2 tons / hectare (213.3 kilograms per acre) and a total output of 750,000 tons. All supply the domestic market, self-sufficiency rate of 12%, still need to import 5 million tons of wheat. Nonetheless, Japan’s wheat research has been very successful and has led the world in many aspects, including wheat genetics, cytology, bioengineering (mainly chromosomal work) and germplasm research

中国商业地产快速发展的背后，是无序的规划与混乱的经营，盲目城市化带来了生态破坏、水土流失。商业地产过热发展已经成为经济领域中的一个隐患。如何才能改变中国商业地产发展的扭曲模式，使商业地产行业走上和谐发展道路？笔者尝试从经济伦理学视角出发．提出中国商业地产走出发展困境、实现和谐发展的新思路。
