In this paper, I explored the micro-aspects of productivity change in the coal industry using mine-level data compiled from official statistics and the original documents of the Coal Control Association. The coal industry in this period was characterized by dynamic changes in market structure. While a number of mines entered and exited the industry, shares of incumbent mines also changed substantially. These mine dynamics had substantial productivity implications. In the early stage of the war, many low productivity mines entered the industry, which reduced average productivity considerably. On the other hand, the government and the Coal Control Association implemented a policy to concentrate productive resources and production on efficient mines during the war, which helped raise average productivity. In a deteriorating environment, coal production in Japan was maintained fairly well during the war. One of the conditions that made it possible was the policy of resource reallocation.", "subitem_description_type": "Abstract"}]}, "item_8_description_6": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "Revised in November 2012.", "subitem_description_type": "Other"}, {"subitem_description": "\u672c\u6587\u30d5\u30a3\u30eb\u306f\u30ea\u30f3\u30af\u5148\u3092\u53c2\u7167\u306e\u3053\u3068", "subitem_description_type": "Other"}]}, "item_8_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65e5\u672c\u7d4c\u6e08\u56fd\u969b\u5171\u540c\u30bb\u30f3\u30bf\u30fc"}]}, "item_8_relation_25": {"attribute_name": "\u95a2\u4fc2URI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.cirje.e.u-tokyo.ac.jp/research/dp/2012/2012cf851ab.html", "subitem_relation_type_select": "URI"}}]}, "item_8_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11450569", "subitem_source_identifier_type": "NCID"}]}, "item_8_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "335", "subitem_subject_scheme": "NDC"}]}, "item_8_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "Center for International Research on the Japanese Economy"}]}, "item_8_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Discussion Paper"}]}, "item_8_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "The University of Tokyo"}]}, "item_access_right": {"attribute_name": "\u30a2\u30af\u30bb\u30b9\u6a29", "attribute_value_mlt": [{"subitem_access_right": "metadata only access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_14cb"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Okazaki, Tetsuji"}], "nameIdentifiers": [{"nameIdentifier": "98469", "nameIdentifierScheme": "WEKO"}]}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Productivity", "subitem_subject_scheme": "Other"}, {"subitem_subject": "producer dynamics", "subitem_subject_scheme": "Other"}, {"subitem_subject": "war economy", "subitem_subject_scheme": "Other"}, {"subitem_subject": "coal", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Japan", "subitem_subject_scheme": "Other"}, {"subitem_subject": "JEL Classification Numbers: L11, L52, L71, N45, N75, N85", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "technical report", "resourceuri": "http://purl.org/coar/resource_type/c_18gh"}]}, "item_title": "Productivity Change and Mine Dynamics : The Coal Industry in Japan during and after World War II", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Productivity Change and Mine Dynamics : The Coal Industry in Japan during and after World War II"}]}, "item_type_id": "8", "owner": "1", "path": ["9/7435/7436", "62/7433/7434"], "permalink_uri": "http://hdl.handle.net/2261/51837", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2017-01-17"}, "publish_date": "2017-01-17", "publish_status": "0", "recid": "42829", "relation": {}, "relation_version_is_last": true, "title": ["Productivity Change and Mine Dynamics : The Coal Industry in Japan during and after World War II"], "weko_shared_id": null}
